Butttonless DFU issue with CONFIG_NFCT_PINS_AS_GPIOS

[chandan]

I am using nrf52832 for button less DFU. DFU is working fine when  CONFIG_NFCT_PINS_AS_GPIOS is not added in applicaton. When added seems like code is getting reset at bootloader level. Is any connection with CONFIG_NFCT_PINS_AS_GPIOS ? Please suggest.

Thanks

Can you provide more details on what the issue is? When exactly does the reset occur?

In order to capture logs from the bootloader you will have to flash the debug version, i.e. nRF5_SDK_15.3.0_59ac345\examples\dfu\secure_bootloader\pca10040_ble_debug. The example uses UART logging by default and you can view it using Putty with the following Terminal settings. 

Best regards

It looks like nrf_dfu_settings_init() is returning a non-zero error code, i.e. not NRF_SUCCESS. Can you set a breakpoint at the if statment after nrf_dfu_settings_write_and_backup() call in nrf_dfu_settings_init() in nrf_dfu_settings.c and see if you hit it? If it does, then please set a breakpoint in on_error() in main.c and provide a screenshot of the call stack.
