It was not some weird state of the A6 pin.
It was the fact that VBat has change to a power input. VBat was 3.3v* the suggested power source for sensitive sensors on the core.
Right now Vbat outputs a voltage of .03v where 3.3v* output a steady 3.3v !
Ah, I was hoping I did not have to re wire these PCBs ! Maybe there is a jumper I can solder to get vbat back to 3.3v Does anyone know ?
