GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc.,
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.

This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

bool "Enable compiler cache"
help
This option will enable the use of ccache, a compiler cache.
It will cache the result of previous builds to speed up future
builds. By default, the cache is stored in
$HOME/.buildroot-ccache.
Note that Buildroot does not try to invalidate the cache
contents when the compiler changes in an incompatible way.
Therefore, if you make a change to the compiler version and/or
configuration, you are responsible for purging the ccache
cache by removing the $HOME/.buildroot-ccache directory.

help
Where ccache should store cached files.
config BR2_CCACHE_INITIAL_SETUP
string "Compiler cache initial setup"
help
Initial ccache settings to apply, such as --max-files or
--max-size.
For example, if your project is known to require more space
than the default max cache size, then you might want to
increase the cache size to a suitable amount using the -M
(--max-size) option.
The string you specify here is passed verbatim to ccache.
Refer to ccache documentation for more details.
These initial settings are applied after ccache has been
compiled.
config BR2_CCACHE_USE_BASEDIR
bool "Use relative paths"
default y
help
Allow ccache to convert absolute paths within the output
directory into relative paths.
During the build, many -I include directives are given with an
absolute path. These absolute paths end up in the hashes that
are computed by ccache. Therefore, when you build from a
different directory, the hash will be different and the cached
object will not be used.
To improve cache performance, set this option to y. This
allows ccache to rewrite absolute paths within the output
directory into relative paths. Note that only paths within the
output directory will be rewritten; therefore, if you change
BR2_HOST_DIR to point outside the output directory and
subsequently move it to a different location, this will lead
to cache misses.
This option has as a result that the debug information in the
object files also has only relative paths. Therefore, make
sure you cd to the build directory before starting gdb. See
the section "COMPILING IN DIFFERENT DIRECTORIES" in the ccache
manual for more information.

Optimize. Optimizing compilation takes somewhat more time, and
a lot more memory for a large function. With -O, the compiler
tries to reduce code size and execution time, without
performing any optimizations that take a great deal of
compilation time. -O turns on the following optimization
flags: -fdefer-pop -fdelayed-branch -fguess-branch-probability
-fcprop-registers -floop-optimize -fif-conversion

does not interfere with debugging.
config BR2_OPTIMIZE_2
bool "optimization level 2"
help
Optimize even more. GCC performs nearly all supported
optimizations that do not involve a space-speed tradeoff. The
compiler does not perform loop unrolling or function inlining
when you specify -O2. As compared to -O, this option increases
both compilation time and the performance of the generated
code. -O2 turns on all optimization flags specified by -O. It
also turns on the following optimization flags:
-fthread-jumps -fcrossjumping -foptimize-sibling-calls
-fcse-follow-jumps -fcse-skip-blocks -fgcse -fgcse-lm

note the warning under -fgcse about invoking -O2 on programs
that use computed gotos.

a reasonable level of optimization while maintaining fast
compilation and a good debugging experience.

Optimize for size. -Os enables all -O2 optimizations that do
not typically increase code size. It also performs further
optimizations designed to reduce code size. -Os disables the

take more time and more disk space, having static libraries
may be useful to link some of the applications statically.

help
A package override file is a short makefile that contains
variable definitions of the form <pkg>_OVERRIDE_SRCDIR, which
allows to tell Buildroot to use an existing directory as the
source directory for a particular package. See the Buildroot
documentation for more details on this feature.
config BR2_GLOBAL_PATCH_DIR
string "global patch directories"
help
You may specify a space separated list of one or more
directories containing global package patches. For a specific
version <packageversion> of a specific package <packagename>,
patches are applied as follows:
First, the default Buildroot patch set for the package is
applied from the package's directory in Buildroot.
Then for every directory - <global-patch-dir> - that exists in
BR2_GLOBAL_PATCH_DIR, if the directory
<global-patch-dir>/<packagename>/<packageversion>/ exists,
then all *.patch files in this directory will be applied.
Otherwise, if the directory <global-patch-dir>/<packagename>
exists, then all *.patch files in the directory will be
applied.

config BR2_COMPILER_PARANOID_UNSAFE_PATH
bool "paranoid check of library/header paths"
default y
help
By default, when this option is disabled, when the Buildroot
cross-compiler will encounter an unsafe library or header path
(such as /usr/include, or /usr/lib), the compiler will display
a warning.
By enabling this option, this warning is turned into an error,
which will completely abort the build when such unsafe paths
are encountered.
Note that this mechanism is available for both the internal
toolchain (through the toolchain wrapper and binutils patches)
and external toolchain backends (through the toolchain wrapper).
config BR2_REPRODUCIBLE
bool "Make the build reproducible (experimental)"
# SOURCE_DATE_EPOCH support in toolchain-wrapper requires GCC 4.4
depends on BR2_TOOLCHAIN_GCC_AT_LEAST_4_4
help
This option will remove all sources of non-reproducibility
from the build process. For a given Buildroot configuration,
this allows to generate exactly identical binaries from one
build to the other, including on different machines.
The current implementation is restricted to builds with the
same output directory. Many (absolute) paths are recorded in
intermediary files, and it is very likely that some of these
paths leak into the target rootfs. If you build with the
same O=... path, however, the result is identical.
This is labeled as an experimental feature, as not all
packages behave properly to ensure reproducibility.

Enable stack smashing protection support using GCC's
-fstack-protector option family.
See

Note that this requires the toolchain to have SSP support.
This is always the case for glibc and eglibc toolchain, but is
optional in uClibc toolchains.

help
Emit extra code to check for buffer overflows, such as stack
smashing attacks. This is done by adding a guard variable to
functions with vulnerable objects. This includes functions
that call alloca, and functions with buffers larger than 8
bytes. The guards are initialized when a function is entered
and then checked when the function exits. If a guard check
fails, an error message is printed and the program exits.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded
Linux systems through cross-compilation.
The documentation can be found in docs/manual. You can generate a text
document with 'make manual-text' and read output/docs/manual/manual.text.
Online documentation can be found at http://buildroot.org/docs.html
To build and use the buildroot stuff, do the following:
1) run 'make menuconfig'
2) select the target architecture and the packages you wish to compile
3) run 'make'
4) wait while it compiles
5) find the kernel, bootloader, root filesystem, etc. in output/images
You do not need to be root to build or run buildroot. Have fun!
Buildroot comes with a basic configuration for a number of boards. Run
'make list-defconfigs' to view the list of provided configurations.
Please feed suggestions, bug reports, insults, and bribes back to the
buildroot mailing list: buildroot@buildroot.org
You can also find us on #buildroot on Freenode IRC.
If you would like to contribute patches, please read

help
Application Binary Interface to use. The Application Binary
Interface describes the calling conventions (how arguments
are passed to functions, how the return value is passed, how
system calls are made, etc.).
config BR2_ARM_EABI
bool "EABI"
help
The EABI is currently the standard ARM ABI, which is used in
most projects. It supports both the 'soft' floating point
model (in which floating point instructions are emulated in
software) and the 'softfp' floating point model (in which
floating point instructions are executed using an hardware
floating point unit, but floating point arguments to
functions are passed in integer registers).
The 'softfp' floating point model is link-compatible with
the 'soft' floating point model, i.e you can link a library
built 'soft' with some other code built 'softfp'.
However, passing the floating point arguments in integer
registers is a bit inefficient, so if your ARM processor has
a floating point unit, and you don't have pre-compiled
'soft' or 'softfp' code, using the EABIhf ABI will provide
better floating point performances.
If your processor does not have a floating point unit, then
you must use this ABI.
config BR2_ARM_EABIHF
bool "EABIhf"
depends on BR2_ARM_CPU_HAS_VFPV2
help
The EABIhf is an extension of EABI which supports the 'hard'
floating point model. This model uses the floating point
unit to execute floating point instructions, and passes
floating point arguments in floating point registers.
It is more efficient than EABI for floating point related
workload. However, it does not allow to link against code
that has been pre-built for the 'soft' or 'softfp' floating
point models.
If your processor has a floating point unit, and you don't
depend on existing pre-compiled code, this option is most
likely the best choice.

based on Cortex-A{8, 9}. If you're unsure, use VFPv3-D16
instead, which is guaranteed to work on all Cortex-A{8, 9}.
Note that this option is also safe to use for newer cores

Cortex-A{8, 9}, even though VFPv3 is technically optional on
Cortex-A9. This is the safest option for those cores.

This option allows to use the NEON SIMD unit, as available
in some ARMv7 processors, as a floating-point unit. It
should however be noted that using NEON for floating point
operations doesn't provide a complete compatibility with the

Acme Systems Aria G25
Build instructions
==================
To build an image for the Aria G25 choose the configuration
corresponding to the Aria variant.
For 128MB RAM variant type:
$ make acmesystems_aria_g25_128mb_defconfig
else for 256MB RAM variant type:
$ make acmesystems_aria_g25_256mb_defconfig
To customize the configuration choosed type:
$ make menuconfig
When you are ready to start building Buildroot type:
$ make
How to write the microSD card
=============================
Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.
Write the bootable SD card image "sdcard.img" onto an SD card with
"dd" command:
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Assuming your Aria G25 baseboard has a MicroSD socket, for example
with the Terra baseboard, insert the microSD card into the baseboard
slot and power it.
To get the kernel log messages you can use a DPI cable
(http://www.acmesystems.it/DPI)
You can find additional informations, tutorials and a very
comprehensive documentation on http://www.acmesystems.it/aria.

Acme Systems Arietta G25
Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Arietta G25. With the current configuration
it will bring-up the board, and allow access through the serial console.
You can find additional informations, tutorials and a very comprehensive
documentation on http://www.acmesystems.it/arietta.
Build instructions
==================
To build an image for the Arietta G25 choose the configuration
corresponding to the Arietta variant.
For 128MB RAM variant type:
$ make acmesystems_arietta_g25_128mb_defconfig
else for 256MB RAM variant type:
$ make acmesystems_arietta_g25_256mb_defconfig
To customize the configuration chosen type:
$ make menuconfig
When you are ready to start building Buildroot type:
$ make
How to write the microSD card
=============================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Insert the microSD card into the Arietta slot and power it.
The image just built is fairly basic and the only output
you will get is on serial console, please consider to use a DPI
cable (http://www.acmesystems.it/DPI)

make socrates_cyclone5_defconfig
Build everything
make
Following files will be generated in output/images
.
├── boot.vfat
├── rootfs.ext2
├── rootfs.ext4 -> rootfs.ext2
├── rootfs.tar
├── sdcard.img
├── socfpga_cyclone5_socrates.dtb

Creating bootable SD card
=========================
Simply invoke
dd if=output/images/sdcard.img of=/dev/sdX
Where X is your SD card device (not partition)
Booting
=======
Pins 6:8 on P18 selector is used to determine boot device. To boot socrates from
sdcard set these pins to value 0x5 (101b). Remaining pins are used to determine
how to configure FPGA and are not associated with booting into Linux kernel.

Arcturus uCP1020 SoM
====================
This tutorial describes how to use the predefined Buildroot
configuration for the Arcturus uCP1020 SoM platform.
Additional information about this module can be found at
<www.arcturusnetworks.com/products/ucp1020>
Building
--------
make arcturus_ucp1020_defconfig
make
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- rootfs.jffs2
+-- rootfs.tar
+-- u-boot.bin
+-- ucp1020.dtb
+-- uImage
Flashing
--------
You'll need to program the files created by buildroot into the NOR flash.
1. Program the new U-Boot binary (optional)
If you don't feel confident upgrading your bootloader then don't do it,
it's unnecessary most of the time.
B$ tftp u-boot.bin
B$ protect off 0xeff80000 +$filesize
B$ erase 0xeff80000 +$filesize
B$ cp.b $loadaddr 0xeff80000 $filesize
2. Program the kernel
B$ tftp uImage
B$ erase 0xec140000 +$filesize
B$ cp.b $loadaddr 0xec140000 $filesize
3. Program the DTB
B$ tftp ucp1020.dtb
B$ erase 0xec100000 +$filesize
B$ cp.b $loadaddr 0xec100000 $filesize
4. Program the jffs2 root filesystem
B$ tftp rootfs.jffs2
B$ erase 0xec800000 0xee8fffff
B$ cp.b $loadaddr 0xec800000 $filesize
5. Booting your new system
B$ setenv norboot 'setenv bootargs root=/dev/mtdblock1 rootfstype=jffs2 console=$consoledev,$baudrate;bootm 0xec140000 - 0xec100000'
If you want to set this boot option as default:
B$ setenv bootcmd 'run norboot'
B$ saveenv
...or for a single boot:
B$ run norboot
Good Luck !

This is the support for the ARM Foundation v8 machine emulated by the
ARM software simulator of the AArch64 architecture.
First, one has to download the AArch64 software simulator from:
https://silver.arm.com/download/download.tm?pv=2663527
Then, use the arm_foundationv8_defconfig configuration to build your
Buildroot system.
Finally, boot your system with:
${LOCATION_OF_FOUNDATIONV8_SIMULATOR}/models/Linux64_GCC-4.7/Foundation_Platform \
--image output/images/linux-system.axf \
--block-device output/images/rootfs.ext2 \
--network=nat
You can get network access from within the simulated environment
by requesting an IP address using DHCP (run the command 'udhcpc').

ARM Juno r1/r0
Intro
=====
These instructions apply to all models of the ARM Juno:
- Juno r0 (does not support PCIe)
- Juno r1 (supports PCIe)
- Juno r2 (Big Cluster with A72)
Buildroot will generate the kernel image, device tree blob, bootloader binaries
and a minimal root filesystem.
How to build it
===============
Configure Buildroot
-------------------
Configuring Buildroot is pretty simple, just execute:
$ make arm_juno_defconfig
Build the rootfs, kernel and DTB
--------------------------------
Note: you will need to have access to the network, since Buildroot will
download the packages' sources.
You may now build your rootfs with:
$ make
(This may take a while)
Result of the build
-------------------
After building, you should obtain this tree:
output/images/
+-- rootfs.tar
+-- juno.dtb (if Juno r0 is used)
+-- juno-r1.dtb (if Juno r1 is used)
+-- juno-r2.dtb (if Juno r2 is used)
+-- Image
+-- bl1.bin
+-- bl2.bin
+-- bl2u.bin
+-- bl31.bin
+-- fip.bin
+-- scp-fw.bin
+-- u-boot.bin
Preparing your rootfs
======================
Format your pen drive as a ext3 filesystem by executing:
$ mkfs.ext3 /dev/<your device>
Preparing your rootfs
======================
Format your pen drive as a ext3 filesystem by executing:
$ mkfs.ext3 /dev/<your device>
Installing your rootfs
======================
After mounting the pen drive please execute the following:
$ sudo tar -xvf output/images/rootfs.tar -C <pen drive mount path>
When completed make sure to unmount the device:
$ umount <pen drive mount path>
Insert the pen drive in one of the ARM Juno' USB type A connectors.
Configure *.dtb in the boot configuration for Juno r0
=====================================================
SITE1/HBI0262B/images.txt
.....
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x00C00000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify Image name to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Configure *.dtb in the boot configuration for Juno r1
=====================================================
SITE1/HBI0262C/images.txt
......
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x00C00000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno-r1.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify target filename to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Configure *.dtb in the boot configuration for Juno r2
=====================================================
SITE1/HBI0262D/images.txt
......
NOR3UPDATE: AUTO ;Image Update:NONE/AUTO/FORCE
NOR3ADDRESS: 0x02000000 ;Image Flash Address
NOR3FILE: \SOFTWARE\juno-r2.dtb ;Image File Name
NOR3NAME: board.dtb ;Specify target filename to preserve file extension
NOR3LOAD: 00000000 ;Image Load Address
NOR3ENTRY: 00000000 ;Image Entry Point
......
Installing kernel image and DTB
===============================
1. Connect to the ARM Juno UART0 and execute USB_ON in the terminal
2. Connect a USB cable between your PC and ARM Juno USB type B connector
A mass storage device should appear in your desktop.
3. Open the software/ folder
4. Copy the 'Image' file to software/
5. Copy the 'juno-r1.dtb' (r1), 'juno.dtb' (r0) or juno-r2.dtb (r2) file to software/
6. Copy the bootloader binaries (bl1.bin and fip.bin) to software/
7. Press the red button in the front pannel of ARM Juno
At this time, the board will erase the Flash entry for each new item and
replace it with the lastest ones.

Introduction
============
Armadeus APFxx are Systems On Module (SOM) based on Freescale/NXP i.MX
processors associated with an FPGA (except on APF28). Non volatile
data are stored in on-module NOR or NAND Flash, depending on the
model. These SOM can be used on Armadeus development boards or with
custom docking boards.
Supported platforms
===================
Buildroot currently supports the following Armadeus platforms with the
associated defconfigs:
* APF27 SOM + devt board -> armadeus_apf27_defconfig
* APF51 SOM + devt board -> armadeus_apf51_defconfig
* APF28 SOM + devt board -> armadeus_apf28_defconfig
Vanilla Linux versions are preferred to Freescale's one in these
configurations.
How to build it
===============
Configure Buildroot
-------------------
Let's say you own an APFxx SOM with it's corresponding development
board, all you have to do is:
$ make armadeus_apfxx_defconfig
where "apfxx" is the version of your SOM.
Launch build
------------
$ make
Result of the build
-------------------
When the build is finished, you will end up with:
output/images/
├── imx**-apfxxdev.dtb [1]
├── rootfs.tar
├── rootfs.ubi
├── rootfs.ubifs
└── uImage
[1] Only if the kernel version used uses a Device Tree.
Building U-Boot is currently not supported in these configurations.
Installation
============
You will require a serial connection to the board and a TFTP server on
your Host PC. Assuming your server is configured for exporting
/tftpboot/ directory, you will have to copy the generated images to
it:
$ cp output/images/uImage /tftpboot/apfxx-linux.bin
$ cp output/images/*.dtb /tftpboot/
$ cp output/images/rootfs.ubi /tftpboot/apfxx-rootfs.ubi
where "apfxx" is the version of your SOM, as used with _defconfigs.
Then on your serial terminal, all you have to do is:
* interrupt the boot process and access U-Boot console by pressing any
key when booting,
* configure board and server IP addresses with "ipaddr" and "serverip"
environment variables,
* if you want to update kernel:
BIOS > run update_kernel
* if you want to update device tree:
BIOS > run update_dtb
* if you want to update rootfs:
BIOS > run update_rootfs
That's it !

This document explains how to set up a basic Buildroot system on various
Atmel boards. Additional details can also be found on the Linux4SAM website:
http://www.at91.com/linux4sam/bin/view/Linux4SAM/
This guide covers the following configurations:
- at91sam9g45m10ek_defconfig
- at91sam9rlek_defconfig
- at91sam9x5ek_defconfig (at91sam9g15, at91sam9g25, at91sam9x25,
at91sam9g35 and at91sam9x35)
- atmel_sama5d3xek_defconfig (sama5d31, sama5d33, sama5d34, sama5d35,
sama5d36)
- atmel_sama5d3_xplained_defconfig
- atmel_sama5d3_xplained_dev_defconfig
- atmel_sama5d3_xplained_mmc_defconfig
- atmel_sama5d3_xplained_mmc_dev_defconfig
- atmel_sama5d4_xplained_defconfig
- atmel_sama5d4_xplained_dev_defconfig
- atmel_sama5d4_xplained_mmc_defconfig
- atmel_sama5d4_xplained_mmc_dev_defconfig
- atmel_sama5d2_xplained_mmc_defconfig
- atmel_sama5d2_xplained_mmc_dev_defconfig
These configurations will use AT91Bootstrap, u-boot and a linux kernel from
the git trees maintained by Atmel.
The configurations labeled as 'dev' provide a development rootfs with tools to
tests the features of the SoC:
- ALSA tools to test audio
- FFMPEG to record video from the ISI/ISC
- I2C, SPI, CAN, etc. tools
- modetest for LCD screens, HDMI
- Wilc1000 firmware for the Atmel Wireless sdio module
- SSH for convenience
- GDB/GDB server for debug
Configuring and building Buildroot
==================================
For most configurations listed above, the Buildroot configuration
assumes the system will be flashed on NAND. In this case, after
building Buildroot, follow the instructions in the "Flashing the NAND
using SAM-BA" section below.
For the Xplained boards, an alternative Buildroot configuration is
provided to boot from an SD card. Those configurations are labeled as
'mmc'. In this case, after building Buildroot, follow the instructions
in the "Preparing the SD card" section.
To configure and build Buildroot, run:
make <board>_defconfig
make
Flashing the NAND using SAM-BA
==============================
Flashing the board
------------------
Connect the board:
o at91sam9g45m10ek: DBGU: J10, USB sam-ba: J14
o at91sam9rlek: DBGU: J19, USB sam-ba: J21
o at91sam9x5ek: DBGU: J11, USB sam-ba: J20
o sama5d3xek: DBGU: J14, USB sam-ba: J20
o sama5d3 Xplained: DBGU: J23, USB sam-ba: J6
o sama5d4ek: DBGU: J22 or J24, USB sam-ba: J1
o sama5d4 Xplained: DBGU: J1, USB sam-ba: J11
Start the board in RomBOOT:
o at91sam9g45m10ek:
1. open JP8, JP10 and JP12
2. start the board
3. close JP8, JP10 and JP12
o at91sam9rlek:
1. J11 on 1-2 (BMS=1), open J12 and J13
2. start the board
3. close J12 and J13
o at91sam9x5ek:
1. open JP9 and:
- Cogent: open *NCS jumper
- Embest: open SW1
- Ronetix: open J1 and J2
2. start the board
3. close JP9 and:
- Cogent: close *NCS jumper
- Embest: close SW1 (ON position)
- Ronetix: close J1 and J2
o sama5d3xek:
1. start the board
2. push BP4 and BP1
3. release BP1
4. release BP4
o sama5d3 Xplained:
1. open JP5 (NANDCS) and JP6 (SPICS)
2. start the board
3. close JP5 ans JP6
o sama5d4ek:
1. start the board
2. push BP3 and BP4
3. release BP4
4. release BP3
o sama5d4 Xplained:
1. close JP7 (BOOT_DIS)
2. start the board
3. open JP7
"RomBOOT" should appear on your console (this should be ttyUSBx or ttyACMx)
Now locate the USB sam-ba interface it should be ttyACMx, usually ttyACM0
dmesg on your machine should give:
usb 1-2.1.4: New USB device found, idVendor=03eb, idProduct=6124
usb 1-2.1.4: New USB device strings: Mfr=0, Product=0, SerialNumber=0
cdc_acm 1-2.1.4:1.0: ttyACM0: USB ACM device
Look for idVendor=03eb, idProduct=6124, this is the interface you want to use.
You can then flash the board using the provided flasher.sh script in board/atmel:
board/atmel/flasher.sh <builddir_path> <interface> <board>
For example, for an out of tree build made in
/tmp/atmel_sama5d3_xplained/ for the sama5d3 Xplained, you would use:
board/atmel/flasher.sh /tmp/atmel_sama5d3_xplained/ /dev/ttyACM0 sama5d3_xplained
Reboot, the system should boot up to the buildroot login invite.
Preparing the SD card
=====================
An image named sdcard.img is automatically generated. With this image,
you no longer have to care about the creation of the partition and
copying files to the SD card.
You need at least a 1GB SD card. All the data on the SD card will be
lost. To copy the image on the SD card:
/!\ Caution be sure to do it on the right mmcblk device /!\
dd if=output/images/sdcard.img of=/dev/mmcblk0
Insert your SD card in your Xplained board, and enjoy. The default
U-Boot environment will load properly the kernel and Device Tree blob
from the first partition of the SD card, so everything works
automatically.
By default a 16MB FAT partition is created. It contains at91bootstrap,
u-boot, the kernel image and all dtb variants for your board. The dtb
used is the basic one:
U-Boot> print
[...]
bootcmd=fatload mmc 1:1 0x21000000 at91-sama5d2_xplained.dtb; fatload mmc 1:1 0x22000000 zImage; bootz 0x22000000 - 0x21000000
[...]
If you want to use a variant such as the _pda7 one, you will have to
update your u-boot environment:
U-Boot> setenv bootcmd 'fatload mmc 1:1 0x21000000 at91-sama5d2_xplained_pda7.dtb; fatload mmc 1:1 0x22000000 zImage; bootz 0x22000000 - 0x21000000'
U-Boot> save
Saving Environment to FAT...
writing uboot.env
done
A 512MB ext4 partition is also created to store the rootfs generated.
If you want to customize the size of the partitions and their content,
take a look at the the genimage.cfg file in the board directory.

This is the buildroot board support for the Avnet Spartan6 LX9 MicroBoard.
The Avnet S6LX9 Microboard is a small USB-Stick sized module containing
a Spartan6 FPGA capable of running the Microblaze softcore processor
together with RAM and FLASH memory.
The board can be bought from Avnet (avnet.com) or from Trenz Electronic
(www.trenz-electronic.de) for a low price.
To run the Linux built with buildroot you have to install the FPGA bitfile
and u-boot as described in the tutorial AvtS6LX9MicroBoard_SW302_PetaLinux
available on http://www.em.avnet.com/s6microboard
On this site also is a forum containing information on how to build your own
Microblaze processor for the Microboard.
The image file (default name is simpleImage.lx9_mmu.ub) has to be copied
to your tftp folder (often /tftpboot/) or can be programmed into the
board's SPI flash.
Sample session:
$ make s6lx9_microboard_defconfig
$ make
$ cp build/linux-<version>/arch/microblaze/boot/simpleImage.lx9_mmu.ub /tftpboot/br12.2a.ub
$ minicom

Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Bananapi M1. With the current configuration
it will bring-up the board, and allow access through the serial console.
Bananapi M1 link:
http://www.banana-pi.org/m1.html
Wiki link:
https://openedev.amarulasolutions.com/display/ODWIKI/Bananapi+M1
This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make bananapi_m1_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
$ sudo sync
Insert the micro SDcard in your Bananapi M1 and power it up. The console
is on the serial line, 115200 8N1.

Intro
=====
This default configuration will allow you to start experimenting with the
buildroot environment for the Bananapi M64. With the current configuration
it will bring-up the board, and allow access through the serial console.
Bananapi M64 link:
http://www.banana-pi.org/m64.html
Wiki link:
https://openedev.amarulasolutions.com/display/ODWIKI/Bananapi+M64
This configuration uses U-Boot mainline and kernel mainline.
How to build
============
$ make bananapi_m64_defconfig
$ make
Note: you will need access to the internet to download the required
sources.
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
$ sudo sync
Insert the micro SDcard in your Bananapi M64 and power it up. The console
is on the serial line, 115200 8N1.

BeagleBoard X15
Intro
=====
This config currently supports the beagleboard x15,
and generates a barebone image.
The image must be flashed to a SD card to be used.
How to build it
===============
$ make beagleboardx15_defconfig
Then you can edit the build options using
$ make menuconfig
Compile all and build a sdcard image:
$ make
Result of the build
-------------------
After building, you should get a tree like this:
output/images/
├── am57xx-beagle-x15.dtb
├── am57xx-beagle-x15-revb1.dtb
├── boot.vfat
├── MLO
├── rootfs.ext2
├── rootfs.ext4
├── rootfs.tar
├── sdcard.img
├── u-boot.img
├── u-boot-spl.bin
└── zImage
How to write the microSD card
=============================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX

CircuitCo BeagleBone
Texas Instuments AM335x Evaluation Module (TMDXEVM3358)
Description
===========
This configuration will build a complete image for the beaglebone and
the TI AM335x-EVM, the board type is identified by the on-board
EEPROM. The configuration is based on the
ti-processor-sdk-02.00.00.00. Device tree blobs for beaglebone
variants and the evm-sk are built too.
For Qt5 support support use the beaglebone_qt5_defconfig.
How to build it
===============
Select the default configuration for the target:
$ make beaglebone_defconfig
Optional: modify the configuration:
$ make menuconfig
Build:
$ make
Result of the build

Some versions of u-boot for this Chromebook check for tpm node
in the device tree and fail badly (reboot) if it is not found.
While not exactly correct, it is much easier to patch the mainline
device tree to match u-boot expectations than to fix u-boot on
this device.

Samsung XE303C12 aka Chromebook Snow
====================================
This file describes booting the Chromebook from an SD card containing
Buildroot kernel and rootfs, using the original bootloader. This is
the least invasive way to get Buildroot onto the devices and a good
starting point.
The bootloader will only boot a kernel from a GPT partition marked
bootable with cgpt tool from vboot-utils package.
The kernel image must be signed using futility from the same package.
The signing part is done by sign.sh script in this directory.
It does not really matter where rootfs is as long as the kernel is able
to find it, but this particular configuration assumes the kernel is on
partition 1 and rootfs is on partition 2 of the SD card.
Make sure to check kernel.args if you change this.
Making the boot media
---------------------
Start by configuring and building the images.
make chromebook_snow_defconfig
make menuconfig # if necessary
make
The important files are:
uImage.kpart (kernel and device tree, signed)
rootfs.tar
bootsd.img (SD card image containing both kernel and rootfs)
Write the image directly to some SD card.
WARNING: make sure there is nothing important on that card,
and double-check the device name!
SD=/dev/mmcblk1 # may be /dev/sdX on some hosts
dd if=output/images/bootsd.img of=$SD
Switching to developer mode and booting from SD
-----------------------------------------------
Power Chromebook down, then power it up while holding Esc+F3.
BEWARE: switching to developer mode deletes all user data.
Create backups if you need them.
While in developer mode, Chromebook will boot into a white screen saying
"OS verification is off".
Press Ctrl-D at this screen to boot Chromium OS from eMMC.
Press Ctrl-U at this screen to boot from SD (or USB)
Press Power to power it off.
Do NOT press Space unless you mean it.
This will switch it back to normal mode.
The is no way to get rid of the white screen without re-flashing the bootloader.
Troubleshooting
---------------
Loud *BEEP* after pressing Ctrl-U means there's no valid partition to boot from.
Which in turn means either bad GPT or improperly signed kernel.
Return to the OS verification screen without any sounds means the code managed
to reboot the board. May indicate properly signed but invalid image.
Blank screen means the image is valid and properly signed but cannot boot
for some reason, like missing or incorrect DT.
In case the board becomes unresponsive:
* Press Esc+F3+Power. The board should reboot instantly.
Remove SD card to prevent it from attempting a system recovery.
* Hold Power button for around 10s. The board should shut down into
its soft-off mode. Press Power button again or open the lid to turn in on.
* If that does not work, disconnect the charger and push a hidden
button on the underside with a pin of some sort. The board should shut
down completely. Opening the lid and pressing Power button will not work.
To turn it back on, connect the charger.
Partitioning SD card manually
-----------------------------
Check mksd.sh for partitioning commands.
Use parted and cgpt on a real device, and calculate the partition
sizes properly. The kernel partition may be as small as 4MB, but
you will probably want the rootfs to occupy the whole remaining space.
cgpt may be used to check current layout:
output/host/bin/cgpt show $SD
All sizes and all offsets are in 512-byte blocks.
Writing kernel and rootfs to a partitioned SD card
--------------------------------------------------
Write .kpart directly to the bootable partition:
dd if=output/images/uImage.kpart of=${SD}1
Make a new filesystem on the rootfs partition, and unpack rootfs.tar there:
mkfs.ext4 ${SD}2
mount ${SD2} /mnt/<ROOTFS-PARTITION>
tar -xvf output/images/rootfs.tar -C /mnt/<ROOTFS-PARTITION>
umount /mnt/<ROOTFS-PARTITION>
This will require root permissions even if you can write to $SD.
Kernel command line
-------------------
The command line is taken from board/chromebook/snow/kernel.args and stored
in the vboot header (which also holds the signature).
The original bootloader prepends "cros_secure console= " to the supplied
command line. The only way to suppress this is to enable CMDLINE_FORCE
in the kernel config, disabling external command line completely.
That's not necessary however. The mainline kernel ignores cros_secure,
and supplying console=tty1 in kernel.args undoes the effect of console=
Booting with console= suppresses all kernel output.
As a side effect, it makes /dev/console unusable, which the init in use must
be able to handle.
WiFi card
---------
Run modprobe mwifiex_sdio to load the driver.
The name of the device should be mlan0.

*********************
* MIPS Creator CI20 *
*********************
Introduction
============
The 'ci20_defconfig' will create a root filesystem and a kernel image
under the 'output/images/' directory. This document will try to explain how
to use them in order to run Buildroot in the MIPS Creator CI20 board.
How to build it
===============
Configure Buildroot
-------------------
$ make ci20_defconfig
Build the rootfs
----------------
Note: you will need to have access to the network, since Buildroot will
download the packages' sources.
You may now build your rootfs with:
$ make
(This may take a while, consider getting yourself a coffee ;-) )
How to write the SD card
========================
Once the build process is finished you will have an image called
"sdcard.img" in the output/images/ directory.
Make sure the SD card is not mounted then copy the bootable "sdcard.img" onto
it with "dd":
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
Insert the SDcard into your ci20, and power it up. Your new system
should come up now and start a console on the UART HEADER.

*********************
* MIPS Creator CI40 *
*********************
This document details how to build and run a Buildroot system on the
MIPS Creator CI40 platform. For more details about the CI40, see
https://creatordev.io/ci40-iot-hub.html.
How to build
------------
$ make ci40_defconfig
$ make
Prepare USB/MMC for boot
------------------------
On successful build, "sdcard.img" file will be created in 'output/images'
folder.
Use following command to write image to bootable device
$ sudo dd if=./output/images/sdcard.img of=/dev/<your-microsd-or-usb-device>
Booting from USB/MMC
--------------------
The boot loader is already present in NOR flash. To boot your newly generated
Linux and root filesystem, you need to interrupt U-Boot autoboot. Current
U-Boot is configured with 2 seconds of boot-delay, after expiry of this
boot-delay timeout U-Boot starts booting the default image. To interrupt
autoboot, press any key before the boot-delay time expires, U-Boot will
stop the autoboot process and give a U-Boot prompt. You can now boot to
your preferred boot method as describe below:
From USB
pistachio # run usbboot
From SD-Card
pistachio # run mmcboot
Persistent boot command
-----------------------
To boot automatically to your preferred boot method, use following command to
make it persistent, for example to automatically boot to usb:
pistachio # setenv bootcmd run usbboot
pistachio # saveenv
Flash new bootloader
--------------------
The bootloader image will be available in the 'output/images' folder. To flash
the new bootloader, copy it to the device and use the following command on the
device:
# flashcp -v u-boot-pistachio_marduk-<version>.img /dev/mtd0
