Part Number: AM4378

i see reference in [u-boot]/board/ti/[board]/board.c to an efuse to get the MAC address in addition to the preloaded MAC address in the EEPROM.  is that efuse loaded by TI in the factory to provide every am437x with a unique MAC address or is that for us to load during our manufacturing process using our own MAC address block?

    Hi,

    The MAC addresses are owned by TI and efused into the part during testing and are unique. These efused MAC addresses will show up as owned by TI on searches. If you prefer your MAC addresses then you would need to modify the u-boot code to set the u-boot environment Ethernet address to ones that your have secured and stored either on eeprom or some other storage device and ignore the ones efused by TI.

    Best Regards,
