'Recovery Failed. Unknown error' nRF52 DK

Ignacio Lopez

I have open a brand new nRF52 Development Kit. It is not recognise by the nRFgo Studio. I have tried the trick you mention on this thread:

https://devzone.nordicsemi.com/f/nordic-q-a/27216/nrf52832-can-not-be-recovered

without lack. I did flash the lastest nRF5x-OB-JLink-IF version 170724. After this trick the dev kit is updated to the latest segger firmware v22g but the recovery still gives an error. 'Recovery Failed. Unknown error'.

Any help most welcome

    Martin Lesund said:
    I find it very strange that you get the error "invalid argument provided --log". Could you screenshot the result of the command "nrfjprog -v" in cmd?

    Next iteration of the question requires of you coming into my office to check it. This argument does not appear on the help list neither on the infocenter http://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.tools%2Fdita%2Ftools%2Fnrf5x_command_line_tools%2Fnrf5x_nrfjprogexe_reference.html

    Second test as suggested. The only difference is the compilation of the j-link firmware although the version is the same

    That is an old version of nrfjprog. Newest version is 9.7.3. You should install a new version from here: infocenter.nordicsemi.com/index.jsp

    Have you read the line where it says 9.7.3 form windows programs?

    From the image, I can see that 5.2.0 is the active version. Try uninstalling, and install it again to see if it helps. nrfjprog -v must return 9.7.3 for it to be active.

    Ok so it was a System Variable issue where both nrf51 and nrf5x were included so it was using the old version of nrfjprog

    C:\Program Files (x86)\Nordic Semiconductor\nrf51\bin\

    C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin\

    After deleting the duplicated line:

    Error. Please see log attached
