nanobsd open /dev/ttyv0: No such file or directory

[eyebone]

hej folks,

after some time, i looked again into building some devices with the neat nanobsd code.
images are building fine now, configurations - seem - to work so far, but running in the following issue which prohibits me to get a shell onto the system:

Jun 17 19:07:02 forum getty[1574]: open /dev/ttyv0: No such file or directory

this of course happens with all the other virtual ttys as well, for some reason i do not get a login through serial console even if:

ttyu0   "/usr/libexec/getty std.9600"   dialup  off secure

is defined i guess it is the same problem, as a virtual /dev/tty has to get assignend.

the hardware i am talking about is a soekris 5501, src tree is uptodate with a stamp this morning for 8-STABLE

thanks and best regards,

Generally you won't have syscons(4) compiled in on a nanobsd kernel, so ttyv* shouldn't exist and must be disabled in /etc/ttys.

Not sure why your serial port isn't working. Check baud rate settings? Is it working with the Soekris BIOS? At what point in the boot sequence does it stop working?

ah ok. makes sense.

well, serial port is working perfectly for soekris bios and freebsd bootup. so i can track the whole process.

now as i think about it i observed different kind of behavior.
usually i am not able through the serial port to get a newline(pressing enter gives no result), sometimes this is working during the boot process but usually not. now ended up at the point where usually the login/password is presented, nothing happens.
i just thought ok thats it, yesterday night i just let it run by accident for >30min. and observed some IRQ error messages. now as i think about it, i will try to reproduce them. and putting them here.

UPDATE

after a timeframe of 30min the serial console was able to send "carriage return" to the device resulted in the following output:

 Jun 17 22:34:38 forum kernel: stray irq7

i recognized, when i wait long enough(the timeframe above) i can use the network interface as well. so for me it seems like that for some odd reason the device is staling somehow ...

best regards,
