Re: [flashrom] BIOS doesn't change

[Wells, Jay]

Hi Carl-Daniel,

Here is the output you asked for. Actually, I did install the 0.9.2
version on the compact flash for the system we are building. I used the
Live CD though to get these files since all I loaded on the CF was the
flashrom application anyway. I already had the Live CD so it was
probably even less trouble. I'm also attaching the datasheet for the
SBC.

Thanks,
Jay

Hi Jay,

thanks for your report. It seems the flashrom version you're using is
ancient, and you might be hit by a few bugs which were present in
versions before 0.9.0.
Could you try flashrom 0.9.2 or even latest svn and send the output (as
root) of
flashrom -V
lspci -nnvvvxxx
superiotool -deV
so we can take a look at your configuration and figure out what's going
on? You can skip the superiotool step if superiotool is not installed
and/or won't compile.

Absolutely, but this might be an artifact of the old flashrom version
which didn't have the paranoid checks modern flashrom has.

Our goal is to have flashrom run fine everywhere, and reports like yours
are crucial for this. Once we have the requested info from you, we can
guide you further and/or directly give you a fix.

Yes, this is very odd. I definitely want to know what happened there,
and if this also happens with latest flashrom.
