Hi everybody,

Just wanted to let you know that flashrom is working successfully on X399 Designware motherboard which has an SPI flash for the Bios / Firmware MX25U12835F ( 16 MB ). I flashed, read back the firmware and rebooted to check if the firmware is successfully running. All good...

Below the logs !

Best Regards,

Aymen.
