Excuse me, I am currently working on the BIOS of the Intel idaville platform, and the BIOS chip used is a 64M WINBOND W25Q512JVFIQ.
After the machine boots into CentOS, I use the command "flashrom -w BIOS.ROM -p linux-spi" and it will return "No spi device given", and the BIOS update fails.
May I ask what method can be used to solve this problem or update the BIOS with flashrom in the OS successfully, or how can I successfully mount the flash?

Waiting for your reply.
