hi,
if you are using an sf100 with a firmware version between 2.1.1 and 5.1.2 (non-inclusive), I would like to know from you if flashrom version r1649 or newer works for you or not. Probing for a chip (even if there is none attached) suffices as a test. Apparently earlier versions do not support setting the spi clock rate, but we always do that (since r1649) and fail programmer initialization on those versions. I try to find out which versions support setting the speed.
BTW did anybody try to contact dediprog and request any information that would help flashrom to support their programmers better?
I would also like to know if any dediprog sf300 or sf600 users are reading this and would like to see support for it in flashrom.
