Random MAC Addresses with i.MX93 Linux

[dpearson]

In our development/automated test environment we assign fixed IP Addresses based on the target hardware MAC address. Unfortunately I've just discovered that the i.MX93 FRDM boards are randomizing their MAC addresses with each boot. 

Is there a way to configure the board to come up with a consistent MAC Address on every boot?

In u-boot. You can use

$setenv ethaddr xx:xx:xx:xx:xx:xx

$saveenv

Hi @dpearson :

Just add xiaochong's good comments,   the other option to set FRDM-IMX93 with fixed MAC address is to program i.MX93 Fusemap BankNum 39  word 3, word 4, and word 5.   i.MX93 Fusemap located at reference manual attachments  named  <i.MX93_Fusemap.xlsx>.
