Hi,
I just checked out the trunk from svn, since it supports the Kabini SPI bus, but I'm unable to flash the BIOS. I see the following message when I run it as:
'flashrom -p internal:laptop=force_I_want_a_brick -w myimage.bin'
"Warning: Chip content is identical to the requested image."
Well... above is pretty much everything to say unless you know your image differs from the chip contents. Why do you think there is anything wrong? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Reading the contents back, I get a different binary than what I flash in, about 192k into the image. - Justin

Hm... the code that produces the warning above does almost the same as a manual read and compare... does the read work reliably (e.g. do files read always have the same md5sum)? -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Yeah, I tried twice, before and after flashing the new image, and both reads are identical. I could chock it up to a potentially bad read if the files differed from the flashed rom on a block boundary, but they differ at 192k+89 bytes, so I'm pretty sure it's just not writing the image. - Justin

Yes, it is definitely not even trying to write because it reads the flash contents, compares it to the file you give it and thinks they are equal. Can you please create a log with maximum verbosity (-VVV) while you try to write and send it to the list, thanks. It might also be interesting to look at the binaries at some point. You can upload them to http://paste.flashrom.org/ (posting them here wont work). -- Kind regards/Mit freundlichen Grüßen, Stefan Tauner

Thanks for your quick replies. The next log will have to wait for Monday, since the machine's at work. Unfortunately I can't provide the BIOS binaries as they contain proprietary code for internal use. - Justin

After trying a local setup, apparently with an older version of this board, it appears to be a write protection change in newer spins of this board, so I'll need to find more information from the hardware group about what has changed. The older board revision that I just tried does flash and verify. - Justin
