Hello,
Sorry if this is an obvious question. Does each Concerto device have a unique MAC address programmed by TI?
The technical reference manual talks about how to change the eMAC individual address registers, and it talks about the default ID stored in OTP, but I don't understand. If I don't change the address myself, will each device already have a unique address or not?
Thanks,
Joel
Joel,
There is no MAC address programmed into the OTP on factory fresh devices coming from TI. The user (e.g. you) have to program the MAC address.
