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

Hi Jared,

The following is the nrfjprog results. I have 5 JTAGs.

51001235    -> J-Link Debugger 1 connected to custom board
685090243   -> nRF52833 DK board 1
685720715   -> nRF52833 DK board 2
483060254   -> Other vendors BLE DK board
50128807    -> J-Link Debugger 2 connected to custom board

The above boards are shown, and it is the same result with SEGGER JLink configurator.

In addition, I have one 52840 dongle for using with Bluetooth LE app, and one PPK2 for power profiler, but it is not shown in J-Link list, which is also not shown when they works correctly with nRFConnect 3.7.0.

Hi Jared,

To make sure understanding the problem, I add some comment.

52840 dongle & PPK2 is not correctly recognized as Nordic devices, which is the same symptom as version 3.8.0, but different error messages in log.

Another observation...

In the above, both J-Link is connected to unpowered target board.

Now I powered one target board (not nRF), and got the following error message.

2021-11-11T05:51:56.374Z ERROR Error while probing devices, more details in the debug log: WRONG_FAMILY_FOR_DEVICE
