Do you have a null-modem cable? Did you see anything on the serial console?
I have such cables; maybe not a serial console, but away from university I have some old analog monitors....
Serial console in this context refers to connecting the serial port of the s4882 to another machine's via null modem cable and using a terminal emulator program like minicom, gtkterm, etc. on the other machine to see what the s4882 is writing to the serial port.
[...] if you grep the source for post_code you'll find some.
Good. I will try this weekend.
What size is your coreboot.rom (ls -l)? What size is your chip? That's a frequent problem. If you had to add another ROM, did you prepend it?
The .rom (saved on a WD 24000 that Slackware 10.2 cannot mount) size had '5:' over 512 Kb I guess. The manual says 4 MB. Apparently my ROM is too small... I doubt I need certain grub2 modules, but I know not what others do.
It's important that the size is exact. Flash is sized in megabits, so 4 Mbits = 512KB. This probably isn't the problem, I just wanted to make sure.
There is a lot of valuable information on coreboot.org. I recommend reading through the developer pages.
Thanks, Myles
Would it help Coreboot more if I make a smaller grub2 to test newer coreboot2 on s4882 asap or if wait a while and 'prepend' (if it involves soldering that is alright.) I know It can be specially configured; maybe that needs more ROM.
Have you tried it with a warm reset? It's a bit of a long shot, but it can affect things sometimes.
I think I at least tried or also turned it on later 1 - 3 times.
It is very unlikely that it is reaching the payload. [...] Grub2 from buildrom works well as long as you substitute ata for hd in the grub.cfg.
I may try but would like to try serial consoles:
I neither want to re-flash [old] BIOS nor yet try coreboot on my alternate Slackware system[....]
