I’m trying the 3.0.1 image on the PYNQ Z-2 board, and it seems that it does not get a proper MAC address.
For example, I am getting
00:00:05:6b:00:b8, which doesn’t seem correct. I have also tried several boards and have encountered a MAC address collision.
Also, on one of my PYNQ boards with the v2.6 image, the MAC address is 00:05:6b:00:b8:a3. It looks like in the v3.0.1 image this is somehow getting shifted right by one byte, dropping the least significant byte (which is unfortunately the most important byte to distinguish between multiple boards)
