Transmit MAC address from BOOTARGS to 3.10.17 linux kernel

Discussion created by Gabriel GRANGE on Dec 9, 2014

We use a RMII in our hardware iMX6 design. We don't have a PHY with EEPROM to store MAC address and we read it from SPI-FLASH in uboot program.

We notice that if we want to transmit MAC address to fec_main.c part of freescale ethernet driver we need to declare “fec_mac=<mac address value>” in bootargs parameters to have a good management. ‘iMX6 SABRE-SD Linux Release Notes’ document and comment in fec_main.c contain some mistake about this point.


I hope this feedback can be useful for other users.


Best regards,
