I've played with EPIA-M tree recently. Interesting facts:
Which tree is this? From your output it looks a little like mine?
Exactly.
What changes did you make for jmp_to_elf_entry?
void jmp_to_elf_entry(void *entry, unsigned long buffer) { void (*kernel_entry)(void); kernel_entry = entry; kernel_entry(); }
Code is from PPC part. I removed flush_dcache();
How much memory is on your board? I think the RAM detection stuff is
256 MB of RAM.
wrong and that's possibly causing FILO problems; from your minicom.capped2.bz2:
I would set ram size to 0x3fc000 Kbytes
Should I learn about a new option inside Config.filo.lb?
and then later, in FILO:
collect_sys_info: RAM 4032 MB
P.S. Booting in cold restart loading "Normal" image. "Normal" image don't boot - it stops at enable_smbus().
Adam Talbot and I have been looking at this; it doesn't seem to be a specific piece of code that's crashing, as we've seen it hang at various points around the initialisation code. My current guess is that some interrupt that we're not handling yet is occurring, or that we need to do some further chipset initialisation before trying to enable the SMBUS.
I've got a list of chipset registers the Award BIOS seems to twiddle, so I might add those to the enable_mainboard function to see if that at least gets us further.
Well, this could help. Can you attach it? I don't remember but it seems to me I've seen somewhere the CMOS map according to each LB decides which image to load "Normal" or "Fallback". Am I right?
