Thanks Glen M , Now I am able to use reset pin as gpio. I enabled nrf-connect.flash.softreset. if I want to implement a hard reset from software is it possible? I have tried NVIC_SystemReset() function but it was not resetting. I have also tried sys_reboot(SYS_REBOOT_COLD) but my other peripheral does not restarting.

If you're using VSCode there is a File->Save Workspace As option that will save your project settings in a file with a ".code-workspace" extension that you can put wherever you want (I put it in the root directory of my software project). That's where I made this change.

hi Glen M how can I implement this softreset feature in my application?? I am confused to which setting.json file need to be edit. for build or flash?? I found .vscode/setting.json , which is blank.

Ah - I found a better solution here: https://nrfconnect.github.io/vscode-nrf-connect/guides/build_bind_tasks.html

About halfway down the page it talks about adding a "softreset" option to the build. It says to add it to your settings.json, but the thing I clicked on when I found this info (somewhere in the VSCode settings) opened up my local project .code-workspace file. Maybe that becomes the settings.json file when you've saved off your workspace as a file like I do.

Anyway, there was a part of the file that looked like this:

"settings": {

"nrf-connect.applications": [

I stuck the code in to turn on soft reset between those two lines as follows:

"settings": {

"nrf-connect.applicationOptions": {

"${workspaceFolder}": {

"flash": {

"softreset": true,

}

"nrf-connect.applications": [

Hi Michael - I've been having this same problem with my nRF52840 on its reset pin (0.18). I just found an older ticket that helped me - apparently the tool that VSCode uses when programming (west flash or whatever) ends up turning it back on.

I found that if I use JFlash for programming in the merged.hex file from my \build\zephyr directory that suddenly my pin works.

It's not a great solution, but at least I know my board isn't broken and I can move on. Hope that helps!

Here's the thread I found:
