[Techtoolslist] 9100 ROM Signature Algorithm

[Martin White]

Hi all,

I'm pretty sure the answer to this is no, but did anyone ever work this one out? Ie how to calculate the sigs from ROMs?

It's never really been a show stopper for me since I check against the CRC32 sigs first thanks to a script that Andy Welburn posted up some years back (with assistance from Chris Hardy I believe?) and then when I know a ROM matches and the fluke can read it in-circuit ok I then use the 9100 to get the 9100 sig.

It's a bit of a drag though as the CRC32 calculation is kinda slow (even on the FT) so it would be nice to have the 9100 sig up front.

Martin.
