Hello Ocean, At the moment we do not support updating the Intel ME region. You may target other regions described by the flash descriptor using the --ifd option, for example `flashrom -p internal --ifd -i bios --noverify-all -w CBR.1.00.01.bin`. Depending on your use case, another option is to modify the flash descriptor to allow the host to write to the ME region. However Intel recommends locking the ME region so that reads and writes to the ME region from the host are not allowed. Please also see https://flashrom.org/ME#Suggested_workarounds for additional guidance. ________________________________ From: Ocean Huang via flashrom <flashrom@flashrom.org> Sent: Wednesday, February 26, 2020 5:20 AM To: flashrom@flashrom.org <flashrom@flashrom.org> Subject: [flashrom] Flashrom tool failed on the Intel Bakerville platform(CPU:SKY-D) Hi Vendor: We have some issue when using flashrom tool update BIOS & ME firmware on the Intel Bakeville platform, you can refer to the below error log, could you please help give some comments or suggestions about this issue?
