nRF Connect Programmer v3.0.4 - Unable to Connect to any devices

[portheng-rath]

I'm having issues with the latest v3.0.4 nRF Connect Programmer. This issue never happens with the previous version.

The Programmer cannot discover any J-link devices, except the Development Kit such as nRF52840DK. 

However, even with the DK, it cannot connect to the device's J-link. 


Here is what the UI displays. I expected 000600110060 and 000051017929. The log says it is discovered, but somehow those aren't listed. 



Here is the debug log for J-link.

Hi,

What is you nRF Connect for Desktop version? When you connect a device to the PC, is this being detected?

-Priyanka

[portheng-rath]

It's v3.12.0. 

Yes it is definitely detected. I still can use J-Flash, J-Flash Lite tool and nfjprog.exe with those J-links. 

It's definitely the nRF Programmer application in nRF Desktop App.

Hi,

I have conveyed this to the team and am awaiting a response.

Hi,

Could you remove all the JLink drivers, reboot and install the JLink_V7.66a again?

Does it work now?

-Priyanka

Hi Priyanka, 

I've tried removing the existing J-link driver, removing nRF Programmer, rebooting my PC, reinstalling J-link v7.66a, and reinstalling nRF Programmer, and it's still not working. See attached image for proof.

Hi,

Sorry for the delayed response as I was on sick leave for a week. I have conveyed this to the team and will get back to you soon with a response.

Have you tried this on another windows pc ? Are you able to replicate this? It's strange that even after reinstalling the software you get this issue.
