Honored ContributorEthernet MAC Address
Which file has the ethernet MAC address? What is the variable name? Any suggestions for making this changable for production?

Altera_ForumI have a script that should allow you to change your MAC address fairly easily. It writes to the last sector of flash which is where the Linux kernel looks for the MAC address.
Which board are you using? I'll test it out on that board for you to make sure it works and then I'll post the script that I use online later- Altera_Forum
I use the Altera Cyclone NIOS board, but I also need to implement it on a custom board. Which source file retrieves/specifies where the MAC address is stored?

The file that reads the MAC address from flash is setup.c and it can be found in <linux eclipse plugin directory>/linux-2.6.x/arch/nios2nommu/kernel.

Hi Ken:
Did you ever post the script? I'm interested in using it with a custom board.

The format of the sector is listed in:
nios2\examples\software\simple_socket_server\network_utilities.c This is actually part of the MicroC/OS-II example, but you should be able to strip out the stuff you need to make your own programming utility.
