Try to do a full erase before flashing the fw. You can use nRF Command Line Tools:

nrfjprog -e

Hi Jared,

Thanks for the reply!

As I attached an image in that there is no any preprocessor declare for reset.

" If you want to use the reset pin as a normal GPIO then you have to remove the pre-processor definition CONFIG_GPIO_AS_PINRESET which is defined in the makefile or project options if you use gcc or SES respectively. You also have to do a full erase, as the PSELRESET register is in the UICR. "

Please guide me how to full erase PSELRESET register ?

Hi,

[ I have placed #define CONFIG_GPIO_AS_PINRESET in sdk_config.h ]
