nrf52832 with freertos,Use P0.09,P0.10 as GPIO,such as button and power hold

[Coder_hope]

I am using nrf52832,I have Defigned "CONFIG_NFCT_PINS_AS_GPIOS"as below。P0.09 is configed as POWER_HOLD pin, P0.10 is configed as buton.

I found that when I download softdevice,P0.09 is Pulled high, the board is powered ,then I download application,P0.09 is still highand board is powered,but 52832 does not work,I must disconnect battery and reconnect it,then I push the button and the system start to run. then I push buton and power off device ,after this startup, even I push the button again ,or reconnect the batery,the system does not startup.

    this really makes me confused,does anyone can help me?

Hi,

Are you testing this on a custom board, or on a nRF52 DK? If you are testing on a custom board, are you able to reproduce the same behavior on a nRF52 DK? The pins should not be configured by downloading the softdevice to the board.

Can you share your project for us to reproduce and debug this issue?

Best regards,
Jørgen

I am testing this on my own desigened board,using SDK 15.0,I can not share this project for some reason,this is 2nd board ,the designer changed button and power hold pin to PIn 0.09 and Pin 0.10,in 1st board,the button and power hold pin are P0.13 and P0.12,this board works well.

Can you check that the NRF_UICR->NFCPINS register is set correctly? You can read it using "nrfjprog --memrd 0x1000120C".

It would also be great if you can post the values of the GPIO registers.

I tested several boards,some boards are abnormal ，some boards are good and work well， the abnormal boards must have welded problems.  thank you for your replay.
