Stellaris microcontroller MAC address
Does anybody know how to reprogram ones programmed and committed
MAC address on the Stellaris microcontroller
Thanks, Darko B.
Under the "Other Utilities" tab of LM Flash Programmer, select "MAC Address Mode" under "User Register Programming". Here, you can type in your MAC Address and select "Program MAC Address". You can also select "Commit MAC Address" to commit it to the MCU.
You can retrieve your current MAC address here as well by clicking "Get Current MAC Address". You should write this down for future reference. If you've performed a "Debug Port Unlock" and you have not documented the MAC address, there is no way to retrieve this MAC address; you will have to program a new one.
I am using LM3S8962 and have committed an incorrect MAC address. I tried Debug port unlock in LM flash programmer build 1381, but it did not reset the mac address. Do you know if the LM flash programmer is supposed to work with LM3S8962.
I have used the same procedure successfully before on LM3S9B96 processor with the same debugger board.
The 8962 is an earlier generation part, and once the USER registers are committed (which is where the MAC address is normally stored), they cannot be altered.
Thank you. I confirmed in the datasheet from TI that user reg0 and reg1 cannot be resetted. It is interesting that the preliminary Luminary datasheet indicated that the factory reset would be possible and I was relying on that one.
