Hello,

My chip is indeed not reacting at all. The interface is working, I see the SPI signals moving on my scope (as expected).
After studying the datasheet of AT25080B, the development guide and the code. I found out that the device is not supporting RDID. In the datasheet there is no ID available. I have seen in the code of flashchips.h there are several device with comments like "/* No ID available */". And from what I understand there is no support of device with no RDID support in flashrom. Hopefully I'm wrong!
How can I add support for this chip in flashrom? Are there examples of device like the AT25080B in flashrom?
Oh, yes that makes sense... I don't think we are prepared for chips without any ID commands yet actually... but you can add and use a fake probing function that simply always returns 1 as a workaround.
