Hi,

 

I have a little question. How can I lock the MAC address fuses?

I have set the MAC address with

 

U-Boot > fuse prog 4 3 0x000000aa

U-Boot > fuse prog 4 2 0x11223346

 

and I get the MAC address 00:aa:11:22:33:46. But then I can do

 

U-Boot > fuse prog 4 2 0x11223347

 

and now I get the MAC address 00:aa:11:22:33:47

 

Is there any fuse prog x y z to lock the MAC address writing?

 

Regards
