Some how when I use the audio hat extension board it causes issues, If I plug audio hat direct into main board no boot issues.?
I ohmed out the traces on on extension board and all seem fine, so not sure but I can go on with calibration and working on optimizing rf cable lengths and ends.
Odd thing is I never had issue with previous builds, I tried previous build and got same result so I suspected hardware.
Good thing is I have plenty of room for audio hat extension is not needed.?
