so I have this board which can turn on with battery, but if i plug charger, it doesnt show any amperage or voltage, if I unplug the battery, i get only 5v but its not turning on, and I see that I don't have ppbus without battery..but its not shorted.
I have tried replacing both cd3215 chip with the chicken wing chip I bought from ali..
