nRF52 Reset

[Abhi]

Hi, I have been trying to figure out how to get the IF BOOT/RESET button on the nRF52 micro-controller working. I have defined "CONFIG_GPIO_AS_PINRESET" under C/C++ in the target options as suggested here: infocenter.nordicsemi.com/index.jsp, I am running the Blinky example. However after I flash onto the board and the LEDs blink as expected, I try pushing the reset button but nothing happens. Is that intended or have I missed a step in enabling the reset functionality? I expect it to revert to the state before anything was flashed onto it, hence "reset" but maybe I have the wrong idea of what this button does. Could someone clarify that as well?

Thank you very much!

A [system] reset is basically just switching the power off and on again. You'd need to erase the chip with a tool or boot into some sorta bootloader mode and erase the chip in a program to do what you figured the reset button would do.

See POWER — Power management in the Product Specification for more information about Pin reset.
