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

Okay, I'm seeing it better now and it isn't removing the block protection.

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. I'm new to Linux and things so we'll see how it goes.

Any help you can offer would be greatly appreciated.

Thanks,
