i can't get any u-boot serial output from miniroot67.fs on a raspberry
pi 3. i'm using a 'FTDI232' which cost ~$4 - USB to 3.3V jumper
cables, connecting TX to RX and vice versa on GPIO header.
my serial console setup works without issue with a pi 1 and a pi 3,
running raspbian, with:
$ screen /dev/ttyUSB0 115200
i had to add 'enable_uart=1' to /boot/config.txt before with console
became accessible, on the pi 3.
i tried mounting the partitions after dd'ing miniroot67.fs and
looking for some text files to edit, but there were only binaries
any ideas? i can only think of trying older miniroots or snapshots
