Very strange behavior, but glad to hear that you are able to continue! Let us know if you start seeing strange behavior again

Below you will find the output of those two. After seeing this I tried again to program and use the cellular monitor and a few other things. All of it works now. This makes no sense as I have not made changes for two days. Im just very glad it works now and c an carry on with the Dev Academy course. Thank you very much for all the help.

Detected SEGGER J-Link version: JLink_V8.60

The device command version you are currently using was tested with a different J-Link version (JLink_V8.66) than the one you have installed (JLink_V8.60). The tested version is not required, and your J-Link version will most likely work fine. If you get issues related to J-Link with your devices, use the tested version.

Are you using our VS Code extension? If so, can you please provide the output from nRF Connect:Generate Support information?

Hello, I've tried installing SEGGER J-Link (8.72) and reproducing your issue, but with no success.

[quote user="Plakkies"], It was not the firmware, I downgraded SEGGER J-Link to v8.6 and here is the log file again after I tried programming the asset tracker again:[/quote]

From what application are you collecting your logs? We will need more verbose logging in order to pinpoint the issue.

What output do you get if you run both the following commands from command line:

nrfutil device --version

and

nrfutil device reset --json-pretty

Kind regards,
Øyvind

Looking at doing the downgrade is scary, It looks like that refers to the firmware on the board. I dont understand when It was changed from the origional. Im concerened to try mess with that. Can you send a link on doing the downgrade properly before I make things worse.

Hello, Thank you for the response.
I followed a guide from Nordic on youtube, I have watched many videos from nordic now and cannot find the exact one I used. I did install the VScode extension, the Segger Jtag something, the sdk and toolchain in vscode.
I ran the blinky pwm example without any problems. I also got the gnss example working. The problem started when I tried to change settings in the vscode gui to try get debug working, I did not change any files directly, so I did not remove any headrs as far as Im aware. when trying nrfutil device list I get:
nrfutil device list
1051282951
Product J-Link
Board version PCA10171
Traits seggerUsb, usb, jlink, modem, devkit

Hello,

How did you install the environment in linux i.e. VS Code extension, SDK and Toolchain?

[quote user="Plakkies"]I get the same error when trying the celular monitor as well. [/quote]

What errors do you see? Can you please provide the log file, and more on the steps you took so that I can try to reproduce?

In command line, what output do you get when running nrfutil device list? Have you removed any headers from the DK e.g. nrf current measurement header?

Kind regards,
Øyvind
