Hi!
as boot arg I have console=ttyO2 which works. But I wonder which device names the uarts have in the /dev
directory. There is no ttyO2 , but ttyS0-3 exist:
crw-rw-rw- 1 root root 4, 64 Jan 25 2012 /dev/ttyS0
crw-rw-rw- 1 root root 4, 65 Jan 25 2012 /dev/ttyS1
crw-rw-rw- 1 root root 4, 66 Jan 25 2012 /dev/ttyS2
crw-rw-rw- 1 root root 4, 67 Jan 25 2012 /dev/ttyS3
but it's not possible to cat anything to these:
# cat gfx_check.sh > /dev/ttyS0
-/bin/sh: can't create /dev/ttyS0: No such device or address
should this work at least for the one that represents the console? of course it works with /dev/console.
