I fnot, can you tell me how to generate it? no, it will not work without one. there is apparently no way to flash beyond the regions defined by the flash descriptor. the layout file can limit the address range accessed (to make it work). depending on how fine-grained you wanna use it you can define in the layout file ranges for each region as defined by the flash descriptor on your board (from this output of flashrom:) 0x54: 0x00000000 (FREG0: Flash Descriptor) 0x00000000-0x00000fff is read-write 0x58: 0x03ff0200 (FREG1: BIOS) 0x00200000-0x003fffff is read-write 0x5C: 0x01ff0001 (FREG2: Management Engine) 0x00001000-0x001fffff is read-write or just define one range for the whole accessible area (that would be something like 0x0 - 0x003fffff i would say) i think you will probably need to set the read_all_first variable in flashrom.c to 0 (and maybe also use the -w parameter) to be able to write without errors printed, else flashrom will try to read the whole flash before and after writing to verify its contents. i have told you already at least twice to look into our documentation. you know that this is my spare time and i am not here to do your work... if you have concrete questions about layout files or their usage we are happy to answer that, but "how do we do that?" makes me kinda angry, if it is already documented. -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Hi all, Sending initial patches, which reduce memory usage for flashrom in coreboot. Look 0-9 patches. To get some laugh at my stupidity look for 10-21 :) Thanks, Tadas

[PATCH] spi25: get rid of unneccessary line breaks (on failed probes)

I thought ramdisks make fine temporary storage? No need to mount harddisk then. It seems a bit strange to claim FreeDOS (or DJGPP-compiled flashrom) ruined your flash image. I guess file hashes would give a definitive answer to what's the issue. I have to admit though that sometimes that FreeDOS kernel has had some FAT-related issues, no guarantee they're all solved. goodluck with CoreBoot as well! So far the Asrock E350 board seems best to experiment with, though I'd like the fanless/passive Asus E350 board instead.

I may have to wait for a while (thankfully I still have a > Windows laptop so I could write up the report on progresses of the firmware > ROM.) the 4 byte RDID warnings should not matter. the chip you have does not need it. it is just printed for other chips that are probed for by flashrom. you can use the -c <chipname> parameter to probe for the correct chip only. regarding the lockup i can't say much without a log, but that it should not happen. :) does it reliably happen while probing for the same chip or is it (seemingly) random? could you also please define "froze" precisely? is it flashrom alone or the whole OS etc? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner
