There is actually a patch to read the whole flash which speeds things up a lot on Dediprog: https://chromium-review.googlesource.com/#/c/240543/ Since that patch touches common code, though, the ME gremlin rears its ugly head and we need to be careful not to read into a read-protected region. So there's still a bit of work to be done (I started on that here: https://chromium-review.googlesource.com/#/c/257191/). If either/both of those patches help, feel free to hijack them and so we can make progress on this. > Thanks! > > -- Steve G. > > On Tue, Jun 2, 2015 at 1:14 PM, Duncan Laurie <[email protected]> > wrote: > >> 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" >> >> -duncan >> >> >> On Tue, Jun 2, 2015 at 11:38 AM, Steve Goodrich < >> [email protected]> wrote: >> >>> I got the Chromium version of flashrom to work, but it takes 20 minutes >>> to flash/verify the 8 MB device.
