https://devzone.nordicsemi.com/f/nordic-q-a/21336/nrf52840-pdk-reset-issueHi, I have disabled the reset functionality of SW5 on nrf52840 PDK by giving the following command &quot; ./nrfjprog --recover -f&quot; as it is mentioned in PDK document. Now I have to make it reset functional. How can I do?
