Hi,
just tried it- this Board uses a Winbond 25Q64FV (64Mbit) and after reading there is an 8MB file, but it is empty. Anything else I should try?
Same here, thanks for the log though :) Your flash controller seems pretty unlocked. That feeds my suspicion that it's not the controller's state that is causing trouble. I guess, I have to go back to the data- sheet.
Btw, flashrom has an option `-o logfile` that makes it easier to catch the output (e.g. you never miss the stderr messages).

Hi,
I added PCI ID for my chipset, but I can't access/ read FLash chip. Any idea how to proceed?
if you compare the datasheets, you'll see that it's incompatible with the 9series PCH.
I'm currently working on upstream support for the Sunrise Point PCH [1]. It's not working yet on my system. But if you want to try it out / help me debugging remaining issues, here's how you can fetch the code:
$ git clone https://review.coreboot.org/flashrom $ cd flashrom $ git fetch https://review.coreboot.org/flashrom refs/changes/40/18940/1 && git checkout FETCH_HEAD
You'd still have to set your chipset to NT instead of BAD in chipset_enable.c.
Nico
PS. You can also try the chromiumos fork of flashrom (can't give you build instructions though).
