Ok this was a vendor board and he is trying to take 1.8V power from pocket beagle PIN 21, this is AN0 which I think is analog input at 1.8V. he is doing it wrong. I dont think he should look for 1.8V supply from the pocket beagle, rather derive it from 3.3V.I gave my feedback thanks for the help!!!!
