Hello,
finally I have time to play with my OPI5, first thing I tried is to install on USB-C, but the port doesn't seem to work. Then I tried to install using USB3 port, on a ssd drive. The armbian-install utility seems to do the job and after installing the bootloader on mtdblock0 I powered off.
At reboot everything is like before: if I remove the sd card the systen won't boot. If I boot with the sd card inserted the root partition is on /dev/mmcblk0p2
First thing that came into my mind is to mount SPI and check if bootloader is ok, but I'm unable to mount it:
~# mount /dev/mtdblock0 /mnt/spi
mount: /mnt/spi: wrong fs type, bad option, bad superblock on /dev/mtdblock0, missing codepage or helper program, or other error.
How can I debug the whole process?
