nRFConnect for Desktop 3.9.0 still has problem with JLink

[choehyunho]

Hi teams,

I noticed nRFConnect v3.9.0 is released.

After upgrading it, I got different errors as following, while detecting my nRF dongle & PPK during BLE app & Power profiler app.

2021-11-10T04:47:51.051Z ERROR Error while probing devices, more details in the debug log: JLINKARM_DLL_ERROR
2021-11-10T04:47:51.051Z DEBUG "Error when running nrfdl_enumerate"

As it says, I tried to find debug.log, but don't know where to find. Let me know if further problem details required.

I am using two J-Link devices and several nRF52833 DKs on my desktop, and using another BLE vendor's board, too.

I can roll back to 3.6.1, and continue to use nRFConnect, but it is quite inconvenient and hope this problem solved.

Is this problem only for my case? I searched forum but no one reported this isssue yet.

Hi,

Could you try using the nrfjprog command:

nrfjprog --ids --log

Does the serial number of the PPKs get listed? 

For the dongle, are you using a stand alone debugger? 

Is the development boards connected directly to the computer, or are you using a hub?

I am using two J-Link devices and several nRF52833 DKs on my desktop, and using another BLE vendor's board, too.

Are you seeing the same issues with the nRF5833s DKs?

regards

I have read https://devzone.nordicsemi.com/f/nordic-q-a/81690/nrf-connect-not-showing-dev-kits-j-links.

My JLink version is v7.58, the latest, but hegitate to downgrade because almost every JLink software upgrades also update JLink internal firmware.

Is there any news about fixing problem about JLink?

Before upgrading to the last version of JLink, I had the JLink version 6.54 (so, way below 7.20a) and was having the problem... Apparently you have to be lucky to have the correct JLink version
