uboot setenv ethaddr

shiyiheng — Thu, 27 Feb 2025 02:29:59 GMT

Hello I want to fix the mac address of the S32G gmac, I execute the following command under uboot

setenv ethaddr d6:20:eb:40:75:d8

saveenv

The mac address obtained when running ifconfig eth0 to the kernel is different from ethaddr. Does the current s32g support mac address passing from uboot to the kernel.

hi,shiyiheng

Are you using S32G2 or S32G3? Which version of BSP are you using?

hi,shiyiheng

Sorry for the reply late.

You can try modifying the u-boot env variable as shown in the picture.

Hope it can help you.
