How to replace OrangePi PC Plus firmware

[Matthai]

I tried to boot my brand new OrangePi PC Plus without SD card, and it boots to some Chinese OS. However, if I boot it with Armbian, it boots to Armbian.

 

So my question is, is there some kind of "BIOS" or similar firmware preloaded on these devices? And if yes - is it possible to remove it with something else?

After having booted Armbian from SD, you can use nand_sata_install.sh to copy the Armbian over the current Android image present in the eMMC.

Then, shutdown, remove the SD, and re-power the board, it will boot Armbian from eMMC.
