Hmmm, I didn't (because it was so slow), but I can do if you think there were issues. I only had a quick look through the image but it looked to be what I was expecting. I'll dump the image using some other software/hardware and make sure that matches too. Unfortunately I think I've only got the buspirate as flashrom-supported hardware. I can't guarantee any FTDI chips I have are legit (ebay...)
