Is there anyone know how to change mac address am3352?

My design uses external phy. And when I check register and wireshark, source mac address is TI's default value.

(in control module, mac_id0_lo, mac_id0_hi)

I was trying to change mac in mac_id0_lo/hi. but its impossible. I know it is only readable.

Please give me idea. How can I change mac address.

The OS in my application is VxWorks.

    Hi,

    We do not support VxWorks, but the MAC address is read from the e-fuse mac_id[1:0]_hi and mac_id[1:0]_lo registers and copied somewhere in the Ethernet driver initialization. You can do your changes at the point where it's read from the e-fuse registers (rewrite code to read it from another location, like an external EEPROM or just hardcode it if you want).
