Debian: MAC address keeps changing on every reboot

[rhille]

I do have the same issue with the stock debian image but there is no mtd3 device found

linaro@therock:~$ cd /dev
linaro@therock:/dev$ pwd
/dev
linaro@therock:/dev$ ls -l m*
crw-rw-rw- 1 root video  10, 56 Aug 27 12:31 mali
crw-r----- 1 root kmem    1,  1 Aug 27 12:31 mem

mapper:

crw------- 1 root root 10, 236 Aug 27 12:31 control

Could it be that it has been already removed as mentioned by ayufan?
If so, it doesn't seem that new solution works as every boot creates a new mac.

Thank you
