So, I connected WP to ground (instead of leaving it unconnected),
and reduced the speed (spispeed=8000). Looking at a binary
comparison of the original file versus what was actually written, it
seems that it was writing parts of it successfully, but corrupting
data every few bytes.<br>
<br>
I'm guessing either the raspberry pi can't handle the higher speeds,
or I'm getting interference from something.<br>
<br>
Either way, I've done a couple erase, write, read cycles and it's
been working fine.<br>

after realizing that the MX25L256 was the wrong chip, I've
obtained a few of the correct chips (MX25L12845EMI-10G). These

Erase/write done.

Your flash chip is in an unknown state.

This is using a raspberry pi as a programmer, and:
<br>
<br>
./flashrom -p linux_spi:dev=/dev/spidev0.0,spispeed=32000 -w
../flashrom/ipmi/SMT_313.bin -o debug1
<br>
<br>
-rw-r--r-- 1 root root 16777216 Jan 2 19:10
../flashrom/ipmi/SMT_313.bin
<br>
<br>
<br>
Any suggestions here? -o debug1 is attached
