Thanks for replying. I checked with serial-console.txt, but it seems I was already doing things the way they should be, I think. Having dug around more, I am now getting the impression that my problem is actually NOT getting console tty1 output to my serial ttyS0... Eg. after boot, I login on ttyS0, ok, I get prompt. If I then login from tty1 (the USB HID keyboard), I don't get any output on serial (ttyS0). BUT if I type in a valid command from USB HID, eg. 'reboot', my embedded system indeed reboots. This leads me to think that I am overlooking something in my config to log console output meant for tty1 (or echoed chars from HID keyboard for that matter) to my *actual* system console, ttyS0. => this is because I'm not using any graphics card or frame buffer (console) on my ARM board. (another option I guess would be to create a frame buffer and have that somehow dumped to ttyS0, but dunno about that). Are you aware of any other config so my tty1 console output (and kbd echoes) are always (also) output on serial ttyS0 ??? in inittab I have (excerpt) : ----------------------------- # Set up a couple of getty's tty1::respawn:/sbin/getty 38400 tty1 (-L and -n switches are no help) # Put a getty on the serial port ttyS0::respawn:/sbin/getty -L ttyS0 115200 vt100 ----------------------------- After logging in from HID kbd tty1, the tty1 getty process properly disappears from ps list. Also, changing the order of console statements on kernel command line makes no difference, unlike outlined in the serial-console.txt docs : mem=64M console=ttyS0,115200 console=tty1 root=/dev/mtdblock1 rw rootfstype=jffs2 Any other help ? It would be nice to be able to retain console output on the serial, but be able to input from the HID keyboard (even if I lose console input from serial ttyS0....) -- Best regards, Kris -- To unsubscribe from this list: send an email with "unsubscribe kernelnewbies" to ecartis@xxxxxxxxxxxx Please read the FAQ at http://kernelnewbies.org/FAQ
