You might also try this technique, though I am not sure if the current version of the 3.2 kernel has this command lin... Michael Williamson
11:26 AM Software Development: RE: Alter Ethernet MAC
Mostafa,
We store the mac address on a eeprom on the SoM. The settings stored on this can be accessed using the f...
