Sabrelite UBOOT has invalid MAC address

[vasant1234]

Hi,

I just got a i.MX6Q SabreLite Board. The problem is that UBOOT shows a MAC address off 00:00:00:00:00:00.

Below is the output of serial console.

I am able to boot Ubuntu but ifconfig shows the same 0 MAC address.

Regards

Vasant

Hello, do you find a solution for your problem?

I've got the same issue, and by google i find only your post here.

When i start the standard linux from sdcard (which was supplied) and execute ifconfig, i don't get any network device.

Hello guys,

You can use fuse index 22 and 23 to set MAC address. Use command "imxotp blow --force <index> <value>.

Fuse index 22 correspond to the 4 lower bytes of MAC and fuse index 23 to the 2 higher bytes.

Let say that we want a  MAC addres of 11:22:33:44:55:66 then we need to type the following commands in u-boot:

u-boot> imxotp blow --force 22 0x33445566

u-boot> imxotp blow --force 23 0x1122

You can also read fuses using command:

u-boot> imxotp read <index>

Reset board after fuses have been blew.
