Some posts are already written about this, but no answer has been given yet, so I’ll give it another go.
We are currently looking into the Rock Pi X as a small workstation system. For our use case, users need to be able to boot from USB, or from the eMMC where a Xubuntu distribution has been installed on. The boot priority in the BIOS however will be forgotten when power is removed. I’m therefore looking into a way to flash a new image where we hard-code the boot priority to be USB > eMMC > other devices.
I didn’t find an answer yet. Does anyone know if there is a possiblity to do so?
