My apologies. I had an out-of-date SRM (A4) I have what I think is the newest SRM (C1), and I do see that it has the table of addresses/lengths that I was missing. I'm talking about the EEPROM onboard the BBB, not the cape's EEPROMs.
I didn't expect that anyone is enforcing valid EEPROM's as it is an open design after all, but I just don't see any provision to avoid serial number duplicates for those who wish to do so. Am I still missing something? I don't see anywhere to encode the manufacturer's name in the EEPROM. Is there some other way for manufacturer's to co-operatively assign unique numbers?
