No CONNECTED DEVICES on VISUAL STUDIO + nRF CONNECT

[Miguel]

Sir, 

I am using a U-BLOX NINA B302 (nrf52840) connected to a SEGGER J-LINK to program it!

Using the J-LINK flash i can program the NINA B302

But, on VISUAL STUDIO + nRF CONNECT i can't see the CONNECTED DEVICES to make the programming.

How can i solve that  and make it find the SEGGER J-LINK ?

It appears that the nRF52840 dongle is not recognized by nrfjprog or the VCS plugin. The DK board works fine. Is there a how-to for using the dongle? I can not connect a J-Link to the dongle.

The nRFConnect for Desktop programmer recognizes the dongle.

The dongle doesn't have the JLINK OB interface hence it is not supported. Currently there is no plan to support devices without JLINK interface. These type of devices are supported by nRF programmer.

Hello. I have the same problem with Visual Studio Code. The Desktop Programmer recognizes the dongle but no the VSC. I understand that I have to use Desktop Porgrammer to flash the code into the board, but I have build the program in VSC and I am not able to find the .hex to flash it with Desktop programmer. Do yoy have any idea where is this file inside the project tree?

Thanks for your time.

Hi,

 

The .hex file will be present in your build-folder/zephyr directory. See this page for more info on how to program the nRF52840 dongle:

Kind regards,
