nRF52832 DK board not visible in nRFgo Studio

Hello,

I have been using nRF development boards for a while, but recently I am currently unable to program my nRF52 development board, due to driver issues. The following command gives me an error.

nrfjprog --program _build/nrf52832_xxaa.hex -f nrf52 --sectorerase

ERROR: There is no debugger connected to the PC.

When opening nRFgo Studio, the board is not visible. My problem seems very similar to this issue (but on the 832):

Using the device manager I uninstall the BULK interface and turn the board off/on.

However when I turn on the board again, it is unable to install the BULK interface, but there is a detected JLINK as seen in the images below.

I have also tried different development boards on my PC and they do not work either. I have also verified that the development boards that do not work on my PC, do work on different PCs just fine. I have also tried reinstalling the SEGGER tool set.

Any thoughts on how this might be fixed would be greatly appreciated.

Thanks,

Mike

Could you try holding in the IF/RESET button on the DK, turn the device off & then turn it on again. Then, the DK should appear in Bootloader mode in File Explorer. Then, you can download the latest version of the OB-JLink-IF file. You can then drag and drop the file to the bootloader folder, which will reset the J-Link interface MCU. After a restart of the DK, the DK should work normally.

Thanks for the fast response.

After updating the OB-JLink-IF as described I still see the same behavior as originally described. I am also seeing this across other Nordic products (the nRF51 Dongle also has this issue where BULK interface is unable to install on my PC)

I have also verified that the development board (and dongle) works on another computer.

Thanks

Are you using Windows 7? Have you tried multiple usb ports on your computer? Seems very weird that it works on another computer, but not on your computer. Seems like there might be an issue with one of your usb ports maybe...

Yes I am currently on Windows 7. I have also tried multiple usb ports and see the same thing. I will be upgrading to windows 10 soon with a fresh install so hopefully that solves this issue.

If you can think of anything else that might help let me know.

Thanks

Will hopefully work better on windows 10 with a fresh install. Good idea. Are you by any chance using a docking station if you have a laptop? Another customer had an issue with an HP laptop & docking station, which led to a similar issue. As soon as he undocked the laptop, he could see the dev kits again & could program using nrfjprog.What kind of a PC are you using?

You might want to update your usb drivers & bios? Might help, but it's probably a better idea to upgrade to Windows 10 & do a fresh install. That tends to help.

One easy tip: have you tried restarting your computer yet?
