I was curious if it was possible to boot from a file of the armbian image in the SD card (not flashed there, but as a normal file in a normal filesystem).
That is not a very simple task. I know I would have to mount the file, chroot to the system, exec init.
In the best scenario, I would have kexec'd the kernel inside the armbian image before exec'ing init.
But kexec'ing (or booting) newer kernels doesn't work here if I booted from the SD card, from a modified multitool image.
I'll provide some when I get a chance this week.
Sadly, I cannot do that. They are government property.
I'll still try to provide pictures of the internals of the devices.
Sorry, I did not read it carefully. Instructions clearly say to erase the eMMC.
They boot from SD if the eMMC is erased.
I was trying to avoid doing that, because restoring the internal storage takes a while.
Because multitool boots from the SD card, I thought there must be a way to boot armbian from the SD card without modifying the internal storage.
I'll avoid talking about brand names from now on. Boards only, got it.
Thank you for your patience.
Sorry for all the confusion you had to deal with.
