Ethernet Static MAC id allocation on yocto zeus kernel or u-boot

[nikhil_sahu2]

Hi All,

I have the Ethernet MAC id stored in QSPI NOR Flash under Partition Name /dev/mtdblock0 in a file. I want to read this file and assign this MAC id permanently to my ethernet port.

This assignment can be done on u-boot or kernel time.

which will be the best way to do this activity also please explain how can we achieve this.

I am using the Imx6 sabresd board and yocto zeus.

Thanks,

Nikhil

Hi Nikhil

one can try to define uboot CONFIG_ENV_IS_IN_SPI_FLASH in

https://source.codeaurora.org/external/imx/uboot-imx/tree/include/configs/mx6sabre_common.h?h=imx_v2...

and use ethaddr uboot environment variable.
