i just had some boot issues with my classic MNT Reform and realized i already have motherboard 3.0 with serial debugging over the new USB-C port, so i was able to inspect the boot process by just connecting my Pocket Reform to it and attaching to ttyACM1
@gkrnours it's just "tio" (serial terminal program) running on the pocket, showing the uboot and linux kernel output of the rk3588 soc in the big (classic) reform while it boots, so i can see what's going on there
