Where the MAC Address is stored in Nitrogen 6Lite boards?.

[andresgonzalez]

Hi.r

We are creating an Ethernet Driver for the Nitrogen 6Lite boards which uses a i.MX6 Solo processor and we want to obtain the MAC address that was assigned by the vendor to the board.

However we don't know where the MAC address is stored. When we read PAUR and PALR we always get 0x00 in all bytes, so we are supposing the MAC address is assigned in other place.

Thanks for your help.

This is from their blog : http://boundarydevices.com/fuse-command/

Does that help ?

That's exactly right. The mac address is stored in OTP fuses reserved for this purpose (Bank 4, registers 2 and 3 in U-Boot addressing).
