Error: Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device, when plugging in my nrf52840 dk board.

Overnight I was running my nrf52 dk board with my stm32 board. I have a spi interface between the two boards that is working properly. When I went to switch out and switch back in the same board, the board does not get recognized anymore. It only shows up as j-link, and displays the error message: Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device. Any thoughts to what may be causing this?

Hi Andew, Since you have a revision 3 nRF52840DK, it's also not possible to reflash the JLink fw for this. I'm afraid you have a faulty DK and might need to replace it then. Regards, Priyanka

Hi Andrew,

Is the nRF52DK being recognized by your PC? Does it get recognized when you connect the DK alone after removing all the connections to it?

Regards,

Priyanka

Hey Priyanka,

When I load device manager with no boards connected to my computer, I have com3 and com4 already taken. When I plug in this board with no wires connected, my computer recognizes it and places assigns it to com8 and com9. I have also attached screenshots of my board, and how programmer on nrf connect looks before and after I plug in my device in question.

NRF Connect Before Plugged In:

NRF Connect After Plugged In:

Device Manager Before Plugged In:

Device Manager After Plugged In:

Picture of Board While Doing all this:

Hi,

Could you try putting the device in bootloader mode? Does this show up in the Programmer?

Priyanka

Hey,

Unfortunately it does not look like I can put the device in bootloader mode. I was able to put my other nrf52840 dk board into bootloader mode, but it does not look like I can do it for the board in question.
