Hi All,

We are trying to update the BIOS using the flashrom utility on the Elkhart Lake (LEC-EL) x86 platform, but we are facing the issue: "linux_mtd_erase: MEMERASE ioctl call returned -1, error: Input/output error" when running the flashrom tool. Please see below the attached error log for your reference.

 System Configuration:

NOTE: We have previously used this tool to upgrade and downgrade the BIOS without issues, but we are currently encountering this error.

ERROR MESSAGE:

Good, writing to the flash chip apparently didn't do anything.
Please check the connections (especially those to write protection pins) between
the programmer and the flash chip. If you think the error is caused by flashrom
please report this to the mailing list at flashrom@flashrom.org or on IRC (see
https://www.flashrom.org/Contact for details), thanks!

Could you please suggest if any kernel configuration needs to be changed?

We would appreciate your input.

Thanks & Regards,
