MAC Address
Thanks, Alec. I was aware of buying numbers from IEEE. Your answer implies that STM has no small lots of numbers available for low volume designs. Is that true?
The other part of my question is, how does each board get its MAC at manufacture/configuration time?
Do I have to set up a patch system to inject the MAC into the loadable firmware at load time? That would be bad for post-ship updates.
Does the HAL have any provision for storing MAC and other config in a small Flash segment that is not wiped in a firmware load?
Or does each developer have to come up with their own scheme? It’s not that hard, we’ve all done it, but I don’t want to do it myself if a standard mechanism exists for STM32.
