SOLVED: RPI5 armtix; cannot login on the debug uart 16 February 2024, 16:38:07 The new raspberry pi 5 has a dedicated serial header.I can see the early messages and if console=ttyAMA10 is added to the cmdline I can also see the kernel boot messages.If I add agetty-ttyAMA10 to services with bps adjusted to 115200 then I also can see a login prompt. However, I cannot seem to get this 'console' to see a keyboard. I'm using elogind and seatd. The normal monitor logins work fine.Is there some configuration I need to do to allow keyboard access? /dev/ttyAMA10 seems to have the same permissions/ownership as other ttys.EDIT: turns out aliexpress debug leads are not all good. Changed to another and keyboard works fine. Last Edit: 17 February 2024, 08:14:30 by replabrobin

I'm using the same setup (except for speed) as I use on the rpi4 where it's connected via gpio to /dev/ttyAMA0.
