Tried to load the LimeSDR-Mini image and it completely locked up the Micro (does not even boot). I hoped that the FPGA image is the same, i was wrong. Needs investigation.

Restored the old FPGA image and board is alive again.

Looks like the FPGA design is heavily modified. Unexpected, i assumed they just slam the LimeSDR-Mini design in there and be done with it. OTOH new code structure looks much cleaner.

There are alot of changes to the PIN planning, not only to placement but also some PIN names have changed: https://www.diffchecker.com/b2E4XW03

So..fixing this will be alot of work, i have to go over each PIN manually, make no mistakes and even then there is no guarantee that it actually works.

Good attack plan would be to go over the working Mini design and keep only the pins that are absolutely needed, verify that stuff still works. Then migrate the pins to Micro.

Tried to port the pins, did not work... too many changes in the design. Will not support.
