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 noticed 3.9.1 has been released, and release note says that something has been modified about this issue, but no changes.

Still my nRF devices are not correctly detected, even if I updated nRF command-line tools, too.

Hi,

What J-link and nrfjprog version are you using now? 

nrfjprog -v

What revision is the PPK2 and the nRF52840 Dongle that doesn't get listed?

regards

PS C:\Users\firebird\Documents\nRFConnect> nrfjprog -v
nrfjprog version: 10.15.1 external
JLinkARM.dll version: 7.58c

I'm not sure how to check b'd revision, but serial numbers of each board are as following.

PPK2 : D176D0DB9DA2

52840 Dongle : F757CDFEDD83

Sorry, I was out of office for a while.

Now I can physically access those devices, and the board revision printed in label is as follows.

PPK2 : D176D0DB9DA2 (PCA63100 1.0.1 2020.47)

Dongle : F757CDFEDD83 (PCA10059 1.2.0 2019.41)

Hi,

I've reported the issue to our developers. In the meantime you could do as suggested earlier to downgrade the J-link driver.
