Nice work so far!
Payload is uncompressed since i had problems with error in decompression from lzma,
What errors did you get?
just decompression error and then hang or reboot, it was some days ago, i can recheck in next hours i think
Machine reboots at point indicated in log but only difference between next loops is like that one below, diff between two restarts from same log.
Jumping to image. coreboot-2.3 Thu Dec 3 00:30:36 CET 2009 booting... Calibrating delay loop... -end 1ee10434f, start 1c570413d +end 2c5cfc8a0, start 29d2fc6b1 32-bit delta 650 calibrate_tsc 32-bit result is 650 clocks_per_usec: 650
This difference makes sense if it is using something like RDTSC to calibrate. It runs from power on, so will be higher after a reset.
I am aware that this change is harmless, but its only change diff found.
Anyone has idea how to debug why it restarts?
I think the problem may be that RAM is not completely functional. Decompression needs RAM, and the payload also needs RAM.
Did you try calling the very simple ram_check() function to test your RAM configuration? And how does the RAM configuration done by coreboot compare with that done by the factory BIOS?
yep, both low 1M, and 1M->memsize, even few times in rows (few times added in C code)
Mostly configuration (register contents) is similar or very, only thing i can't change is APBASE register thus i disabled AGP interface.
