I'm not so familiar with these logs but can you try any of these below.

- Change pool to test
- Reset the miner by holding the reset/IP button for 15 seconds then release
- Replug all PSU cable and ribbon cable

If it still doesn't work try to flash the miner there is someone here who share love core a1 firmware you can check it from this link below.
