hmm that doesn't look like the usual --readhmid output.
Pncconf can try to piece together internal data from a --readhmid --sserial output.

That's the hm2 driver startup output

If the OP doesn't post a pinout file, I can do it tomorrow

(don't have a 7C81 or RPI at home, and stopping by work
this close to dinner time was vetoed by the boss)

If you update mesaflash to the latest, it should print out the DB25 pin numbers in the first column.

Ok, checked out the repo and built it, then it produces this output:

Which looks very much like what I expect. I suppose I will need to generate the configuration, and then besides changing the board name and the command, I will need to also change the pin mappings after I run through pncconf. Still not really sure what I need to enter and where in pncconf.

Thanks,
Brian
