Hi,

Any idea of what algorithm and bytes to use to update the CRC/Checksum in the flash image?

The mac address is stored in the image.  I have written a script to update the mac address and know where the CRC/Checksum is.  I have tried various algorithms (those supported by Hex Workshop- Checksum-8 and -16, CRC-8 and -16, etc. w/1’s and 2’s complements) but am unable to duplicate a known checksum.

Hardware is a  Kontron ETX Express module,  flashrom reports:   ‘Found Chipset “Intel ICH8M-E”  …’,   ‘Found chip “SST SST25VF016B”  …’

Thanks in advance,

Bill Flanders
