## Flashing an ODROID-N2+
|
||
|
||
Home Assistant can be flashed to an ODROID-N2+ by connecting the device directly to your computer via the USB-OTG connection on the front of the board. The device contains the Petitboot bootloader, which allows the ODROID-N2+ storage to show up as it were a USB drive.
|
||
|
||
_All these instructions work the same for the ODROID-N2 (non-plus version)._
|
||
|
||
### What you will need
|
||
|
||
To flash your eMMC using Petitboot and OTG-USB, you will need the following items:
|
||
|
||
- HDMI cable and monitor
|
||
- USB keyboard
|
||
- USB 2.0 to micro-USB cable
|
||
- If your board came in a Home Assistant Blue: No.2 hex key to open the case
|
||
|
||
### Enabling SPI boot mode
|
||
|
||
To enable the SPI boot mode:
|
||
|
||
1. Power off the ODROID-N2+ by unplugging the power cable.
|
||
2. Remove the case.
|
||
|
||
|
||
|
||
3. Locate the toggle for boot mode and switch it from MMC to SPI.
|
||
|
||
|
||
|
||
4. Connect the ODROID-N2+ directly to your computer via the USB-OTG port located on the front of the board.
|
||
5. Connect a USB keyboard and a monitor (using HDMI) to your ODROID-N2+.
|
||
6. Plug in the power cable to power on the ODROID-N2+.
|
||
|
||
### Enabling USB drive mode
|
||
|
||
After The ODROID-N2+ is set to SPI boot mode and powered on, it boots into a terminal. To enable the USB drive mode:
|
||
|
||
1. Select `Exit to shell` from the menu.
|
||
|
||
|
||
|
||
{% note %}
|
||
When using the command line, it may return the following message:
|
||
`can't access tty; job control turned off.`
|
||
You can safely ignore this message and proceed with the installation
|
||
{% endnote %}
|
||
|
||
1. Use the following command at the console to confirm the storage device node:
|
||
|
||
```bash
|
||
ls /dev/mmc*
|
||
```
|
||
|
||
2. Set the storage device on the ODROID-N2+ as a mass storage device using the `ums` command (USB Mass storage mode).
|
||
This will configure the ODROID-N2+ and OTG to act as a memory card reader:
|
||
|
||
```bash
|
||
ums /dev/mmcblk0
|
||
```
|
||
|
||
### Flashing Home Assistant
|
||
|
||
1. Connect the ODROID-N2+ to your PC via the micro-USB port at the front of the ODROID-N2+.
|
||
2. When the ODROID-N2 is recognized as a USB connected storage device, you can flash the eMMC with [Etcher](https://www.balena.io/etcher/).
|
||
- Use the latest stable version of Home Assistant OS for the [ODROID-N2+](https://github.com/home-assistant/operating-system/releases/download/{{site.data.version_data.hassos['odroid-n2']}}/haos_odroid-n2-{{site.data.version_data.hassos['odroid-n2']}}.img.xz) (haos_odroid-n2-{{site.data.version_data.hassos['odroid-n2']}}.img.xz).
|
||
- In Balena, use **Flash from file**. **Flash from URL** does not work on all systems.
|
||
|
||
3. When the flash process is complete, disconnect the ODROID-N2+ from your PC.
|
||
- Remove the power cable.
|
||
- Remove the USB and HDMI cables.
|
||
- Make sure to toggle the boot mode switch back to MMC.
|
||
|
||
4. Put the ODROID back in its case.
|
||
5. Connect your ODROID-N2+ to your network with an Ethernet cable, make sure there is internet access, and plug in power.
|
||
|
||
6. If your router supports mDNS, you can reach your installation at `http://homeassistant.local:8123`.
|
||
- If your network doesn’t support mDNS, you’ll have to use the IP address of your ODROID-N2+ instead of `homeassistant.local`. For example, `http://192.168.0.9:8123`.
|
||
- You should be able to find the IP address of your ODROID-N2+ from the admin interface of your router.
|
||
7. Continue with [onboarding](/getting-started/onboarding/). |
