STM32MP157A ethernet MAC address not setting?

[Sindhu Vadde]

Hi,

We are using stm32mp157a processor in my custom board. I need to change MAC address because in uboot log it is showing it is showing invalid MAC address. I am setting MAC address using setenv ethaddr 11:22:33: 44:55:66 command. But when i set ethaddr i am getting following error messages in uboot log. you can see my log below. i have followed stm32mp1 trouble shooting guide.

STM32MP1 bring-up troubleshooting guide

How can i come out of this issue. Please help us.

Hello @Sindhu Vadde​ ,

I think this is a protection for different variable of U-boot that are read-only. The config that allow you to modify this ethaddr variable in u-boot console by setenv command is CONFIG_ENV_OVERWRITE and is disabled by default by ST. Can you try to enable it and try again your change ?

Kind regards,

Erwan.
