Varification trouble - flashrom v0.9.9-r1954, Intel I210 NIC over SPI, Microchip SST25VF040B

[Lamont Dean]

Hello,

Flashrom can find the Intel I210 NIC SPI connected to the SST25VF040B flash
chip and seems to program but fails to verify and gave me this email to
write to about it.  The output is included below.  Before and after a power
cycle the Intel I210 still says its in its unprogrammed state.

I'd like to program a Microchip SST26VF016B flash in place of the
...25VF040... but its not on the list so I'm going through the comments I
found on the wedsite Design Guide
https://www.flashrom.org/Development_Guidelines.  I'm new to Linux and
things so we'll see how it goes.

Any help you can offer would be greatly appreciated.

Thanks,
