Cool, something like that is on my long-term todo list... (with some
additional test stand hardware).
I don't have time to look at the code right now so just some quick
question: the primary/secondary programmer scheme is used to verify one
while the other is used as kind of golden sample, right?
It might make sense to not limit this to two programmers but have one
golden sample and an unlimited programmers to actually test.
(The hardware i was talking about above would be a PCB that can be
remotely cross-switched between any of the attached programmers and
multiple flash chips (e.g. one at45db, several ordinary *25*, some
newer *25* with 4B addressing etc.)
