nrf52 USB isnt detected

Raz_k

I'm getting started with nrf52840DK.

But when i connect my USB i get this error message:

i saw in this topic that when i press on the boot/reset long press when turning the DK on i should help.
However i still get the same error message.

    Hello,

    Make sure you are connecting to right USB port, see the picture below (marked with red). Please make sure all the switches marked with green are in correct position. See this page.

    Are you able to see your device inside the device manager(Device Manger-->Ports-->Jlink).

    Kind  Regards,

    i changed the switch's as describe in the picture.
    However, i cant connect to the device. nef connect programmer sees a jlink and isnt able to erase or flash. 
    Led 5 is on and i'm getting this note:

    No operations possible for device.

    If the device is a MCUBoot device make sure it is in the bootloader mode
    i found this issus: No connection with nRF52840 DK from PC via USB (J2)? and tried uploading the bin file in to the bootloader, but after it is uploaded the driver is disconnected from my pc. then i turn it on (no boot press) and it has the same problem as before.

    Hello,

    To narrow down the issue, I recommend following the below steps:

    • Try connecting the DK to another PC and see if the device is getting detected properly. If it's working fine on another PC, then we can confirm that there is no issue with the hardware (nRF52840DK).
    • Use a different USB cable. Make sure that your USB cable supports both power and data. Some of the USB cables are built only to provide power.
    • If you are using a USB hub, I recommend connecting it directly to the PC port.
    • See this page from the Segger article about the incorrect J-Link driver. Try to follow this and see if it resolves your issue.

    Kind Regards,

    Abhijith
