Finding and Changing the MAC Address
The MAC address on the T4240MFCS is set by the
ethaddr
environment variable in U-Boot.
If ethaddr is not set, it can be set using the
setenv
command.
Example
setenv ethaddr 00:11:22:33:44:55
The MAC Address can be found using the
printenv
command in U-Boot.
Example
printenv

bootargs=root=/dev/ram rw console=ttyS0, 115200 rio-scan.scan=0
fsl_fm_max_frm=9600
