Hi,

you are trying to write the original image while running coreboot,
right?

You are using a very old version of flashrom. Please verify that the
content of the flash is untouched (by using the -v option with the
image you have written successfully last). If it was modified try to
rewrite that image. If that still does not work, please report back,
else update and retry.

Flashrom erase failure

[Racine, Michel]

Thank you for the quick reply.

I have upgraded flashrom. I did a verify, and flashrom indicated a difference. I tried to re-flash coreboot, but I think I'm missing something:

root@debian:~/flashrom/flashrom-0.9.6.1# ./flashrom -p internal -w ~/coreboot.rom
flashrom v0.9.6.1-r1564 on Linux 2.6.32-5-686 (i686)
flashrom is free software, get the source code at http://www.flashrom.org

Calibrating delay loop... OK.
coreboot table found at 0xc717d000.
Found chipset "AMD SB7x0/SB8x0/SB9x0". Enabling flash write... The SB700 IMC is active and may interfere with SPI commands. Disabling write.
OK.
Found SST flash chip "SST25VF032B" (4096 kB, SPI) at physical address 0xffc00000.
Write/erase is not working yet on your programmer in its current configuration.
Aborting

Thoughts?

Cheers,
Michel Racine
