 If your single-board computer uses a current generation SoC listed on http://opensource.rock-chips.com/wiki_Main_Page the odds are in your favor.

+**My Android device is not listed, will it be added in the future?**<br>
 You may have luck if your device vendor is open source friendly, otherwise keep using Android for best support.
 
+**My device does not boot and I don't understand why.**<br>
+If your device has Android or any sort of vendor u-boot preinstalled in EMMC or SPI, make sure to add `ROCKCHIP_LEGACY_BOOT=1` when building an image.
+This is done automatically for supported devices, which are known to come with Android preinstalled.
