Hi all,
After doing a quick search on the forums, I could not finding much information regarding unique serial numbers for the TM4C129x chips (specifically TM4C129NCPDT).
I have a custom board utilizing the ethernet capabilities of the TM4C129NCPDT chips. I am looking for an "automatic" way of programming the MAC addresses into the board. I understand that this could be done through LM Flash Programmer, however our company intends to creates hundreds of this custom board. Suffice to say, manually programming each MAC address is inefficient.
The first 3 bytes are set (intending to use the first three bytes used by TI), however I am intending on using unique serial number to calculate the next 3 bytes of the MAC address. In short, is there a unique identifier PER chip that I can access through my application? If not, is there another way to program a MAC address automatically without user interaction?
I did read something about the DID0 register, but from what I have read and understand in the datasheet, the value inside will be similar for every chip in the same family.
A quick note - these boards will ONLY be used in-house.
Thank you,
Stephen
