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,
