nRF52840-DK not detected

xhr0428

I just bought a new nRF52840-DK. But it cannot be detected when connecting to the computer. In nRF Connect Programmer, it shows "Unsupported device. The detected device could not be recognized as neither JLink device nor Nordic USB device. "

I tried nrfjprog commands

nrfjprog —family nRF52 —eraseall returned

JLinkARM DLL reported an error

nrfjprog —family nRF52 —recover returned

Recover failed. Please make sure that the correct device family is given and try again

I also tried to follow the steps in the below thread, but after copying the file to JLink folder, only a FAIL text file appeared in the folder. The text file has this line inside "The currently active SWD interface does not support MSD drag and drop"

 nRF52840 dev board not detecting 

How should I get this to work? Thanks

    Hi,

    What version of the nRF52840 DK is this?

    The version should be printed on a sticker on the DK, with the code for the nRF52840 DK (PCA10056) followed by a version number and a date on the format YYYY.WW (where YYYY is year and WW is week number.) Recent DK versions are not necessarily supported by old nRF Command Line Tools versions or older J-Link drivers.

    The latest version of nRF Command Line Tools is version 10.16.0. You can check what version you have through the command nrfjprog --version. If you have an older version, please upgrade to the newest version and try again. Remember to accept the J-Link install as well, for the latest J-Link drivers. The latest nRF Command Line Tools and J-Link driver support the latest DK revisions.

    Let me know if the above does not work, so we can look further into the issue.

    Regards,
    Terje
