It looks like the code tries 12MHz by default but can be set to 24MHz which is worth a try.

I think the syntax would just be "-p dediprog:speed=24"

I got the Chromium version of flashrom to work, but it takes 20 minutes to flash/verify the 8 MB device.  So, while "working" is far better than "not working", it is a bit sluggish.  :-)

Any thoughts on speeding it up?

I have a DediProg SF100 programmer that I want to use with flashrom under Linux.  Unfortunately, the SF100 has firmware version 6.5.03 and I can't use flashrom with it.

I'm looking for a solution.  Does anyone have (or know where/how I can get):
1) A version of SF100 firmware that will work with flashrom?
2) A version of flashrom that will work with SF100 6.5.3?
3) A Linux tool -- other than flashrom -- that will work with the SF100 with its current firmware?

Thanks for any help you can provide!

Hi Steve,

There is a patch in the chromium flashrom tree that add support for firmware 6.0+ (which may or may not include 6.5.3) that does not seem to be in the upstream flashrom:

I suspect the chromium flashrom tree has diverged enough from upstream that it will not apply cleanly there but it is only a 130 line patch so it shouldn't be too bad to integrate if needed.
