Problem with Flash and Debug in VS code

[Thomas]

Has anyone experienced the following error when Flashing (and debugging) from within VS Code. I have no idea what has happened, but it has hit several projects.

Even though it claims that flash has been programmed in last line, this is not true. Using Debug with Ozone will program the flash correctly.

-- west flash: using runner nrfutil
-- runners.nrfutil: reset after flashing requested
-- runners.nrfutil: Flashing file: D:\Workspaces\azure_iot_hub_8\build\merged.hex

Hi, 

Could you run "nrfutil self-upgrade" and "nrfutil upgrade", and then try again? 

If it doesn't help, please generate the support information by the top right of the Welcome view and upload the support information via toolbar -> Insert -> file. 

Also, provide the return after running "nrfutil list".

Regards,
Amanda H.

Hmmm

PS D:\ncs> nrfutil self-upgrade
Usage: nrfutil [OPTIONS] COMMAND [ARGS]...
Try 'nrfutil --help' for help.

Error: No such command 'self-upgrade'.

PS D:\ncs> nrfutil upgrade
Usage: nrfutil [OPTIONS] COMMAND [ARGS]...
Try 'nrfutil --help' for help.

Error: No such command 'upgrade'.

PS D:\ncs> nrfutil version
nrfutil version 6.1.0

nrfutil version 6.1.0

It's quite old, so it doesn't have the upgrade function. 

Please refer to Installing nRF Util and downloading the nrfutil executable file from the nRF Util product page.

[Thomas]

I installed latest SDK and latest toolchain from the VS code menu. It was working... It check your link...
Where would it normally be placed?

[Thomas]

Latest version is installed and old version removed. 

But still unable to debug.

Symptoms have changed, I do not get trace in the output window anymore. Now I just have unexpected GDB output in the DEBUG console.

I can still program with Ozone but sometimes build fails so I need to run it two times before I have a HEX file.
