0x11 is no hashrate in 5 minutes.
Focus on these two logs ECHU[1 1 1] ECMM[1] it seems the hashboard is detected but it's not communicating properly to the control board.
Would you mind to check the conductive copper sheet if you screw them well or do I think you need to try to remove the copper sheet and clean it with isopropyl alcohol and use sandpaper to clean the terminals reassemble and test it again? Make sure that you fix the screw properly to make sure it powers up these two hashboard.
