nRF52832 is it possible to clear CONFIG_GPIO_AS_PINRESET via software?

[Philip]

I have CONFIG_GPIO_AS_PINRESET defined in my project (both bootloader DFU and main program), so pin 21 is setup as hardware reset.

I would like to disable this function for a test, so would any of the following be possible;

1 - Is it possible to turn it of in software by modifying NRF_UICR->PSELRESET ?

2 - If not would it be possible to remove the define from just the main program and rebuild?

3 - Would the chip need a full erase, and the define removed from the DFU project before re-build / re-programme?

Thanks

Hi,

I would use option 2 and remove the define perform a full rebuild (clean/build). Then I would fully erase the nRF and upload the SoftDevice if required and then your app.
