RE: How do I enable p0.21 to use the reset button..?

Hi,

The nRF52 DK (with nRF52832) does not have the reset button connected to the reset pin (P0.21) on the nRF. You can short SB17 to get the reset pin out on a pin header to make it easy to hook up a button or a jumper wire, though.

I am using the nRF52DK board, and later I will use the system reset on the nrf52832 custom board.

I modified the pin a little at pca10040.h.
Is it related to this?

Are you working on nRF52840-DK or your own custom board?

Hello, Eugene.
There is no problem using reset button when connecting board via USB However, if you remove the USB and operate it with a coin battery, the reset button will not be available.
Can you tell me why and how to solve this?

Thank you.

Hello,

All the SDK examples are supporting reset pin(P0.21) by default.
