I am working on nrf52832 and i designing the custom board for the same for my application , which all pins i need to select as programming pins to dump the code on my chip??
Since the MCU is an ARM Cortex you need to use SWDIO/SWDCLK to program it, along with a VCC and GND connection. The pins for SWDIO and SWDCLK are fixed, so you need to use those.
As a side note. The SWD pins can't be used for anything else (unlike on some MCU's where SWD pins can be reconfigured by the Application to become GPIO)
