Re: Baytrail issue to communicate with superios.

Hi,

Dne 01. 12. 23 v 16:04 Jose Trujillo via coreboot napsal(a):
> Using "superiotool" to scan for SIO devices finds Winbond W83627DHG and dumped all its registries but doesn't show Fintek f81803 because of lack of support, so, data exchange between the processor and the SIO chips via LPC port seems to be fine, maybe just need to fix the interrupt issues.

Sorry I don't know much about your particular system. Can you get coreboot serial console on your fintek superio?
If yes, then likely something is wrong with interrupts.

You can use isadump to try to obtain UART1 and UART2 configurations (LDN 1 / LDN 2)

isadump -k 0x87,0x87 0x4e 0x4f 1
isadump -k 0x87,0x87 0x4e 0x4f 2

Says what?

You can also try to setup UART in linux as if those were working, like setting up baudrate / minicom
but then doing:

isaset -f 0x3f8 0x42

Should print "B" on the other side on COM1 (check address where your fintek uart is)

Thanks,
Rudolf
