[flashrom] BIOS. Read failed. Transaction error.

[thirumalai kumar]

Hi,

I am trying to update BIOS using flashrom in linux. This is Intel haswell
board. i am trying to read the chipset name and download the existing BIOS
image to verify whether flashrom is supported on this board or not. After
this i am planning to use flashrom to upgrade BIOS on this. But the read
operation itself is failing. Attached the log.


*./flashrom -p internal*


*Calibrating delay loop... OK.*

*Found chipset "Intel C610/X99 (Wellsburg)".*

Is the read operation failing due to the presence of ME region? Do i need
to use vendor provided flasher utility to upgrade BIOS?

Thanks in advance.
