what could be the problem?
My 1c has the serial port on a superio chip. I recognize this problem from other boards. I also have a 3c3 where I saw this before I fried the 5536 ATA driver.
Sorry didn't understand what you actually mean here... that I have fried my hardware?
The serial port on alix1c is on the Winbond superio chip. The alix2 and 3 boards do not have this superio chip and their serial port is connected directly to the 5536 - and this is probably the reason that serial doesn't work anymore.
that's interesting.. but seems like kernel correctly detects ttyS0 and spits it's messages to it
.... console [tty0] enabled console [ttyS0] enabled .... Serial: 8250/16550 driver $Revision: 1.90 $ 2 ports, IRQ sharing disabled serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A ....
but after init starts it doesn't work anymore :( devise is present: ls -la /dev/ttyS0 crw-rw-rw- 1 root root 4, 64 Oct 9 21:06 /dev/ttyS0
any clue how I can get it working?
What coreboot have (or does not have) so that serial console in linux (busybox particularly) stops working? Or is it busybox's fault? (don't think so as it works with native bios)
