Hello,

Stefanct on freenode:#flashrom requested I email this to you.

I've successfully reprogrammed a M25PE40 device, which was listed as
untested by SVN flashrom.  Setup info and related TTY log follows.

http://pix.jbevren.net/e/LTV/leaptv-debrick

The ROM is left in-circuit, and the LeapTV is powered up after the
Raspberry Pi boots.  Power is provided by the LeapTV system board.  More
relevant information is available on the page linked above, including an
image of the setup.
