Ethernet MAC ID can be set in 3 ways.

  1. MAC ID can be set dynamically while booting in uboot. Use the below command:

    setenv ethaddr <MAC_ID>
    saveenv; boot

  2. The same MAC ID can be set in Uboot source code in file “include/configs/imx8qm_.h”. Set the MAC under the env variable “ethaddr” and “eth1addr”
  3. Last method is to write the MAC ID to OTP. This procedure in on-time programmable. Cannot be reverted. Set the MAC ID in uboot env to “0” or null. The OTP programmed MAC ID will be automatically read during the boot.
