Re: [flashrom] AMD - SP5100 - take SPI ownership (1/2)

[Racine, Michel]

Hello Rudolf,

With your patch, I had a small compile issue (imc.c, function mbox_wait_ack, commented call to msg_pwarn).

I attempted to use the exe, but it cannot turn off IMC. Not sure what you need from here. I can change the code, or gather any data you want.

Output of flashrom execution:

./flashrom_imcpatch -p internal

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.
Found chipset "AMD SB7x0/SB8x0/SB9x0". Enabling flash write... (Shutting down IMC failed!)
FAILED!
FATAL ERROR!
Error: Programmer initialization failed.

Please let me know what you suggest we do next.

Thanks,
Michel.

Hello Rudolf,

I'm assuming I only need to apply the a.patch you sent (not the imc.patch) to the source for 0.9.6.1. I will test this on an AMD Persimmon board (it won't boot currently, I need a dediProg because I bricked it).

I'll update soon,
Cheers,
Michel.

Hi all

I tried with IMC activated on coreboot (Hudson chipset) and it works as expected. Attached patch only tweaks messages and removes now redundant check from sb600 SPI. If IMC is active and firmware handoff fails, then it exits with fatal error.

Signed-off-by: Rudolf Marek

It would be nice if someone else could test this (and dont forget to be able to recover from bad flash)

Thanks
Rudolf
