Hi, I have two customs boards and on the one with the QFABA0 I can go to system off and see 0.6uA of consunption but on another board with the QFABB0 I go into system off but the consunption still 4mA. I'm saying the board went into system off because when I push the button it reset. The radio part on the boards are very similar and on the board with the QFABB0 I don't have the swdclk external pull-down (I tried with that too, same result).
I'm using the following code to test:
