Cable issue? Flashrom doesn't detect F2A-85M's flash chip (25Q64F)

[Daniel Kulesz]

Hi folks,

for backup purposes, I am trying to do some flashing of the BIOS chip from my Asus F2A-85M (Winbond 25Q64F) by connecting it to a RPi2. In the past, I used the RPi2 setup successfully to flash the Macronix chip in the X200 using a 3M test clip and 15cm jumper cables, but I don't have a clip for Winbond chip on the F2A-85M so I am using the connectors which came bundled with a Buspirate (making the wires a little longer in total).

Unfortunately, Flashrom does not detect the chip even when supplying the -c parameter. Here are some pictures of my setup:

I tried several times, checked the pinout and tried attaching the connectors to different areas of the flash chip's heads. Is there anything I am doing obviously wrong?

Cheers, Daniel

Hi Daniel

I had some issues with Buspirate firmware not being updated.
Take a look at this post. Maybe it can help.
