Hi! I'm after a little help. Any idea how to make up an SD card image which has a mainline linux (Armbian) U-boot and just a FAT partition which U-boot can see? I need to be able to load arbitrary binaries using the U-boot console via serial. I'd appreciate any input on this. Something in recent linux versions has broken CuteCom pretty badly so I can't seem to manage X/Y/ZMODEM transfers to RAM easily any more.
If there's any info on using the OTG port or ethernet for the same thing, please point me in the right direction?
