flashrom status for GA-MA790X-UD4

[Yann Droneaud]

Hi,

Flashrom seems to not support Gigabyte GA-MA790X-UD4.

I've only tested read operation, which failed, so I did try the write
operation.

Here are messages from flashrom:

flashrom v0.9.0-r643
No coreboot table found.
Found chipset "AMD SB700", enabling flash write... OK.
This chipset supports the following protocols: LPC,FWH,SPI.
Found board "GIGABYTE GA-MA78GM-S2H", enabling flash write... FAILED!
Calibrating delay loop... OK.
Found chip "SST unknown SST SPI chip" (0 KB, SPI) at physical address
 0x100000000.

If you need details, you can downloads flashrom -V, dmidecode, lspci
outputs at:

  output_flashrom_V.txt.gz
  output_flashrom_rV.txt.gz
  output_lspci.txt.gz
  output_lspci_vvvxxx.txt.gz

Hi Yann,

thanks for your report. I have looked at the log and the "FAILED"
message is harmless. I will try to improve the wording a bit so users
are not scared anymore.

The verbose flashrom log you provided helped me track down the problem.
Sometimes, the SB700 SPI controller only retrieves 2 bytes of flash chip
ID instead of 3 bytes.
Please keep the logs available so others can analyze them as well. Thanks.

I know someone who can reproduce the bug. Once the bug is fixed, I'll
send you another mail.

This will be done.

Feel free to send me patches to test (for probing and read operations only :)

Hi Yann,

the SB700 SPI bug should be fixed in latest flashrom svn (since r661).
Please retest with
# flashrom -V
and report back. Thanks!

Seems to work, thanks.

Here is the report:

flashrom v0.9.0-r664
No coreboot table found.
Found chipset "AMD SB700", enabling flash write... OK.
This chipset supports the following protocols: LPC,FWH,SPI.
Found board "GIGABYTE GA-MA78GM-S2H", enabling flash write... FAILED!
Calibrating delay loop... OK.
Found chip "SST SST25VF080B" (1024 KB, SPI) at physical address 0xfff00000.
No operations were specified.

I tried a read operation

You could have a look at the logs here:

https://mais.quest-ce.net/flashrom/ga-ma790x-ud4/r664/

output_flashrom_V.txt.gz
  output_flashrom_Vr.txt.gz

As "enabling flash write" is reported as FAILED, is it possible to write a
BIOS image ?
BTW, i not ready to try it, but i'm willing to try it by the end of august.

Thanks a lot.

Regards.

Thanks, it seems like my bugfix works as expected.

Thanks! Looks good.

Yes, it should work fine. Only the board write enable is failing, and
that is due to a too generic match which was designed for other boards.
Your board should work fine despite that error message.

Your tests already helped me a lot.
