Glad to hear that!

Closing this case again then!

Best regards,

Hi Simonr,

The issue has been finally resolved here:

the last version 2023.4.148 of nRF Connect for VS Code can't found JLink devices

Sorry about the late reply. I've been out of office for travel this last week. This case is more than a year old at this point, so I'd recommend creating a new ticket where you describe your issue in detail and potentially link to this case if you find it relevant. Please specify what this board that doesn't show up as a connected device is. Is it a custom board connected to a J-Link or another DK of some sort?

Best regards,

Simon

Hi,

Out of blue sky, I have a similar issue today (everything was working 1h ago):

(I tried to restart mac/reconnect Jlink/update FW of the Jlink)

I don't see the Jlink in "connected devices", but I'm able to manually program the board... I can use nrfjprog, I can use Segger Embedded Studio... But I can't see the Jlink in VSC (therefore I can't debug) :/

If I connect, for example, Nordic DK (PCA10056), It shows immediately under the "connected devices".

Any ideas?

Thank you

RE: nRF Connect for VS Code does not detect JLink Device even though it is listed

Simonr — Mon, 21 Mar 2022 12:30:09 GMT

Okay, there should be a "erase" and "recover" option under "Connected Devices" as well you see, do you see those? We're looking into it but haven't been able to reproduce it yet.

Best regards,

Simon

dstarling — Thu, 17 Mar 2022 18:04:45 GMT

I think it is odd too, looks like it should be working, but it doesn't and it was at some time in the past. The failure is when pressing flash under actions.

Under Connected devices I only see icons for RTT terminal, Erase Board, Recover Board and Reset Board. These seem to not apply to the chip, but the Segger (or dev board), so I am hesitant to try these items.

So if my understanding is correct, then there is not an equivalent command under "Devices"?

RE: nRF Connect for VS Code does not detect JLink Device even though it is listed

Simonr — Thu, 17 Mar 2022 12:41:17 GMT

This issue is still being looked into, but I have an update:

The No devices connected error message seems to come when there are no devices to pick from on the computer, which is odd, since we clearly see the same information on the CONNECTED DEVICES sidebar. I assume you aren't disconnecting the device before trying to flash? We also have a mechanism to filter down devices to pick from but I don't see why that would be in effect here.

It would be nice to know if you're clicking flash in the "Devices" panel or the "Actions" panel, and whether either works or if they both fail.

dstarling — Mon, 14 Mar 2022 19:19:42 GMT

I have tried both a Segger JLink Pro and Segger JLink Plus Compact. Same results, they appear in the list of devices, but every time I press flash, it says "no device available"

RE: nRF Connect for VS Code does not detect JLink Device even though it is listed

Simonr — Mon, 14 Mar 2022 14:41:55 GMT

Hmm, okay, can you provide some information on what this J-Link device you use for flashing the external board is? A Development Kit or a J-Link from SEGGER?

Best regards,

Simon

RE: nRF Connect for VS Code does not detect JLink Device even though it is listed

dstarling — Fri, 11 Mar 2022 17:32:05 GMT

As for the latest VS Code update, it means no change, the original issue is still present.

Yes, if I press the debug button the same device will erase/program the flash and go into debug mode, but when selecting either flash option, it reports no device is available despite it being listed.

Shown above is the device drop down selected, it shows the processor attached as expected

Simonr — Fri, 11 Mar 2022 13:06:13 GMT

[quote user="dstarling"]Retesting just now, still now working.[/quote]

I assume you mean still not working here?

Is the J-Link device used for programming an nRF Development KIt or some other J-Link device? Can you also open the dropdown menu of the connected device?

Best regards,

Simon

Retesting just now, still not working. This is a custom board, but it was working previously.

RE: nRF Connect for VS Code does not detect JLink Device even though it is listed

Simonr — Thu, 10 Mar 2022 13:54:45 GMT

What version of VS code do you have, there was an issue quite recently with a VS code hindering users from flashing devices using J-Link. Can you try going to Help ->Check for Updates... in the dropdown menu in VS code? Version 1.65.1 should be fine. Is the J-Link device an nRF Development KIt or some other J-Link device connected to a custom board with an nRF?

Best regards,

Simon
