Hi there,
I've just acquired a RPI5 and I'm looking to set it up via buildroot.
Having flashed my OS image I'd like to view the console so that I can debug my build. I note that there is a 3-pin uart connector, but I don't have the pi debug probe (yet). I then hoped that connecting my existing USB serial device to pins 14 and 15 on the hat gpio interface, along with ground, might be sufficient to view the console as an alternative to the uart connector. I believe these pins were used on previous devices for the console (I may have that wrong).
My kernel command line is set to:
Should I just buy the pi debug probe, or should something like the above approach be viable to obtain a console?
Thanks.
