Hello, I have a strange thing happening on the i810 port I am working on. When
I
power the board on i do not get any serial console from coreboot. VGA
turns
on and works fine, but no serial output. The strange part is if I push
the
reset button, serial console comes up and works fine until the next
power
off. The SuperIO is SMSC LPC47M102 and I am using
superio/smsc/smscsuperio.
Just wondering if anyone else has encountered this before. Any help / thoughts would be appreciated.
Your Super IO chip is not initialized correctly. Compare the register output after reset and from cold start.
You mean with superiotool?
That might already be too late
Did you run the same coreboot image already when you pressed the reset button, or did you initially boot with the BIOS?
Yes, same coreboot image.
So booting Linux fixes the issue? Does serial console in linux work on a cold boot?
