Hello,
I am using an FT2232H mini module for flashing an AT25DF321A SPI flash under linux (Ubuntu 10.10, kernel 2.6.35-32-generic), which is supported according to your Supported Hardware list. I have tested several flashrom revisions (v0.9.2 pré-compiled, v0.9.5 and V0.9.6.xx compiled with GCC 4.4.5).
* with rev0.9.2, the device is listed as UNTESTED when reading, writing or erasing. I have multiple errors when accessing the device but I can read, write and erase small amount of data.
* with rev0.9.5, I also have some issues with the device, but with a few retries I am able to fully read, write and erase the chip, which is also listed as UNTESTED.
* with rev0.9.6, however, the device is listed as Unknown SPI chip and I cannot access it.
Have you already noticed this issue ?
Best regards,
