[AMD Official Use Only - Internal Distribution Only] Thanks David. I tried flashrom1.2 , W25Q128FW and W25Q256.W are not in the support list. I want use Raspberry only to flash W25Q128FW and W25Q256.W. Hi Yulia, Can you add W25Q128FW and W25Q256.W to flashrom support list to use Raspberry only? Thanks for your responding.

Hi Amin, Please note that the W25Q128FW is a 1.8V chip, while Raspberry PI IOs are 3.3V. For Dediprog, pass in the `voltage` parameter, e.g. `flashrom -p dediprog:voltage=1.8 -r foo.bin` Also, as Mike mentioned it will help if we know the version of flashrom which you are trying to use. Some distributions provide very old versions.
