Hi folks,
Ok, ive had a play around with the code for LB to see if i can find where its failing and have found the following :-
in file : src/northbridge/via/vt8623/raminit.c
I added a couple of line to show were in the file its crashing :-
/* setup cpu */ pci_write_config8(north,0x50,0xc8); pci_write_config8(north,0x51,0xde); pci_write_config8(north,0x52,0xcf); pci_write_config8(north,0x53,0x88); pci_write_config8(north,0x55,0x04); print_debug("vt8623 init step 2\r\n");
well, you are becoming a linuxbios hacker, I think :-)
b = smbus_read_byte(0xa0,17);
this is kinda weird. On a via chip the lockups always occur on the northbridge, not on spd ...
Ok, after finding this line, i hunted for the source for smbus_read_byte which i belive is in : src/southbridge/via/vt8231/vt8231_early_smbus.c (am i corect in thinking this??????)
probably ... I think so.
look in the generated auto.inc in the build directory and you'll see where that function came from. This is the best I can do right now, worry. The ctags stuff does not extend to the romcc files.
One last thing, am i correct in thinking that simply going into src/targets/via/epia-m/epia-m/ and running 'make clean', 'make' is enough to recompile all the routines (including the southbridge stuff)?
yes.
