MAC Address EEPROM (not from eFUSE)

[dnsry]

Hi,

We have a custom IMX6DL board. It has an I2C EEPROM with MAC address in it. We want to use this MAC address instead of the eFUSE option of the imx6. We are able to read the MAC address from I2C EEPROM at the u-boot, but do not know how to pass this address to kernel to so that the card's MAC address is taken from the EEPROM. Can you help?

Thanks

Hi V B

one can look at function fec_get_mac_addr() in ..linux/arc/ar/mach-mx6/mx6_fec.c

Since "eth=" command line argument is depreciated from the standard Linux kernel,

one can add it himself using example in sect.18.4.5 "Adding BSP Support for a

New Boot Command to Select CLAA057VA01CT LCD" MX53UG

Best regards

igor

Hi igor,

Thank you.

As suggested by you I looked mx6_fec.c and took the MAC address from eth= parameter passed from u-boot..
