Erase works (I compared the chip content before and after), but the write process fails. I can easily test if you need, because I have a backup BIOS chip.
hi and thanks for your report!
to me it looks like erase is also failing. your -VE log shows:
Erasing and writing flash chip... Trying erase function 0... 0x000000-0x01ffff:E, 0x020000-0x037fff:E, 0x038000-0x039fff:E, 0x03a000-0x03bfff:EERASE FAILED at 0x0003a705!

Looking for another erase function. No usable erase functions left. FAILED!
then writing will fail too of course...

Sorry, I didn't notice that. It's strange, because I ran the following sequence: flashrom -r before.bin, flashrom -VE, flashrom -r after.bin. The chip had a previous BIOS from another board (before.bin) and after flashrom -VE the file after.bin is empty. I checked both in a hex editor.
