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

Thu Dec 14 00:32:24 CET 2017

I've checked voltages on write protect and hold pins and searched through
the code hoping for some extra bit of insight.  I've now changed to the
Microchip SST26VF016B flash chip that I wanted originally and have added
the part to the flashrom flashchips.h and .c. Flashrom now recognizes the
SST26VF016B flash chip and tries to program it but can't verify the code.
The SST26VF016B doesn't have the block protection that the others do and
programs once the write enable command is sent.  Flashrom looks like its
sending the right enable code so I'm not sure what's going on.

Thanks,

LaMont
