Custom Button in DFU

[Dev1]

Hello, 
I am using dfu in custom board and physically we have other button. 

I have changed NRF_BL_DFU_ENTER_METHOD_BUTTON_PIN in DFU app , but after update-ing the application doesn't start. 
When I am using dfu without this modification, application is starts  but after reset dfu not shown. 

What I am missing, in which file I need do modifications? Maybe in boards.h?

Hi Syuzanna

I believe this is because Pin P0.10 (and P0.09 for that matter) is configured as an NFC pin by default. When using SEGGER Embedded Studio, go to Project > Edit Options > Code > Preprocessor > Preprocessor Definitions and add the CONFIG_NFCT_PINS_AS_GPIOS variable in order to use the NFC pins as GPIOs.

Best regards,

Simon

Hi Simon, 
The result is same, when I am done some modification in dfu. 

Even I only add varaible in Preprocessor Definitions without changing the PIN the result is same. 
Maybe I need to change some parts in Linker part too?

Hi

You'll have to configure the NFCT pins as GPIOs in both the application and DFU projects.

 What do you mean here? Does the DFU not work even if you leave the pin config to the state it was originally in? Also, please tell me if you see any errors when compiling/flashing your application.

Best regards,

It is works now. Seems I had problems with power.

Thank you for your help.
