Hi Ivan, Hi Nico,
thank you very much for your help!
Using the raspberry for BIOS flashing is an overkill IMHO. You could use a much simpler USB programmer CH341A, which is supported by flashrom and costs peanuts ( $2-$3 )
I ordered that device and will give it a try as soon as it arrives.
if I understand the datasheet of that chip correctly, flashrom should at least detect a related chip (that might even be compatible for your pur- pose).
Do you have a link to that datasheet? I could not find it on their homepage.
Please send a verbose log of your flashrom run (preferably taken with `-o logfile.txt` appended to your flashrom command). If you use a Rasp- berry Pi, most common problem is an unknown clock. The linux_spi pro- grammer has a `spispeed` setting that you should set to a reasonable value (it's in kHz, so try values between 100 and 10,000).
Thanks for the hint, I will try that as well soon.
Fabian
