Hi,
Dne 03. 10. 20 v 16:16 Paul Menzel napsal(a):
I’ll try to figure out, what is wrong with the Super I/O settings in the devicetree. Removing the devicetree Super I/O configuration already gets rid of the hang, but causes other problems. Help is appreciated.
Please can you check how the LPC decode registers are setup? The 14.3 device has some registers to setup what is going to be sent to LPC bus. There are bits for fixed legacy regions like COM1 etc, and then there are bigger 3? programmable ranges.
Maybe this is in conflict with legacy I/O which causes the hang.
I don't know the right file, maybe it is in
src/southbridge/amd/agesa/hudson/lpc.c see hudson_lpc_enable_childrens_resources() Maybe booting with debug verbosity would tell.
"hudson lpc decode:%s, base=0x%08x, end=0x%08x\n",
Thanks, Rudolf
Kind regards,
Paul
