Downgrading Jlink to 6.54c version did the magic!

Thank you very much, Martin Lesund!

Setting up working environment can kill a man!

Cheers,

Bojan.

Hi Bojan,

Could you maybe check the "nrfjprog --version" on your old laptop as well?

I would suggest trying to downgrade the Jlink version to the one I have.

Hello, Martin Lesund.

nrjprog version: 10.5.0

JlinkARM.dll version: 6.60d

I was able to successfully open Programmer App and update the modem on nRF9160-DK board but from my laptop that is quite older compared to my main desktop computer I am currently using. On my desktop, I am unable to use Programmer app. When I select PCA 10090 device I have the issue I described above (white screen and app freezing).

I agree that nRF9160-DK is OK. However, I still have an issue with using Programmer App on my desktop computer. For your info, unlike Programmer app, LTE Link Monitor app is working properly.

Could the problem be in my computer ? What should I do in that sense to resolve the issue?

Sincerely,

Bojan.

Hi Bojan,

There is most likely nothing wrong with the version of the nRF91 DK you have.

Let us check out which version of "nrfjprog" you have. Please open the Command Line and type "nrfjprog --version":

If you have another version, I would suggest that you update it.

Connect the nRF91DK to your computer and make sure that the Serial port is not opened in another application like Segger emb. studio or the Programmer app.

Then open up command prompt and type: (doc reference)

nrfjprog --recover -f nrf91

Then I want you to open the Programmer App and try to update the modem. (if not successful please send the output log)

If that is successful you can flash the default Asset Tracker sample: devzone.nordicsemi.com/.../nrf9160dk_5F00_asset_5F00_tracker.hex

Either use the Programmer app or open the command line inside the folder you downloaded the .hex file:

nrfjprog --program nrf9160dk_asset_tracker.hex -f nrf91 --sectorerase -r --verify

Best regards,

Martin L.
