Re: Programming BIOS with Flash Programming Tool from UEFI shell

Hi Matt,

I have modified the MRC_SETTINGS_PROTECT and SOC_INTEL_COMMON_PCH_LOCKDOWN
options, still the same issue.

In some cases, "Error 28: Cannot find ME client" error is observed.

But with flashrom, i am able to update the flash from OS.

Whether the coreboot supports programming with FPT? or it only supports
flashrom?

Thanks & Best Regards,
Moorthi S
