Hello,
here is a patch to support EN29LV800BB flash devices via CFI. I have
successfully tested ist in openocd 0.5.0 with the hardware described here:
http://www.bettyhacks.com
It was posted by telek...@gmx.de in the bettyhacks forum for openocd
0.4.0 and integrated into 0.5.0 by me.
Kind regards,
Gunnar Henne
