Re: [coreboot] Flashrom won't work with DediProg SF100 fw 6.5.03
Thank you all (David, Duncan, Vadim, and others in private messages) for your help. Just to speed things up, I'm going to avoid the VERIFY pass (-n parameter). This takes it from 18-20 minutes to under a minute. This is workable for my short-term need, and I'll have time to look at in when I'm on the plane. -- Steve G.

I'll give that a shot (thank you). I notice that the VERIFY is requesting 256 bytes at a time for all 8 MB... wouldn't it be better to use a page size from the flash chip (like 4 KB)?

Re: [coreboot] Flashrom won't work with DediProg SF100 fw 6.5.03
It looks like the code tries 12MHz by default but can be set to 24MHz which is worth a try.
