Raoul is a prior Nordic employee, so that is the Nordic response on this ticket. If you have a related question, please create a new ticket as this is rather old at this point.

Best regards,

Has Nordic commented on this? I don't see any responses from them.

This is a poor work-around. The right way to do it is to check if the firmware has changed and ONLY erase//flash when it has. This is the expected behavior for such a tool.

Raoul Thank you for the suggestions.

This is definitely preferable to the default behavior, thank you for pointing this out.

It might still be good to have a mode that would reflash if there was a binary mismatch to avoid debugging with incorrect symbols if you forgot to reflash manually. But this definitely solves the bigger issue.

Hi everyone!

There are two options for this:

- Create a custom debug configuration, and set the flash property to false. See docs here: https://nrfconnect.github.io/vscode-nrf-connect/connect/advanced_features.html#custom-launch-and-debug-configurations

- Set nrf-connect.debugging.flash to false in your VS Code settings

Best regards,

Raoul

Agreed, it should check first like Ozone. For large applications especially the delay is not insignificant.
