Buttons and LED's does not work

[Jenzo]

I have developed software for a custom board (#1) with the nrf52832-CIAA (QFN packet) with LED's and buttons. It works.

I use the same software for another custom board (#2) with the nrf52832-CIAA (BGA packet) with LED's and buttons. It does NOT work. No LED or Button is working. The #2 board is advertising - I can connect, etc. 

I have changed the corresponding logical I/O's to match #2 in my custom_boards.h file.

I am using the same Softdevice for both boards.

Could you please advice me on what to look.

Hello,

Since the radio seem to work, then I suggest to just run some simple blinky to verify that all GPIOs work as intended. If I were to guess, then you may check if you have some debugging enabled, which may block/assert if for instance UART have hardware flow control enabled, for instance on pins now also configured as led or button.

Best regards,

Kenneth

Hi Kenneth,

How do I configure the PIN input if I have button and Vbatt power? Meaning when I push the button the NRF52 receives Vbatt directly on the PIN input. I have tried PULLUP, etc. but nothing works.
