    • J-link EDU mini DLL ERROR

      New

      Hello everyone,
      I just bought a J-link EDU mini in order to train myself to bootload an Adafruit Feather nRF52840 Express because I want to put the nRF shield on a card to learn how to use BLE. So I downloaded the J-link Software and documentation pack and also the commands line tools from nordicsemi.com, but I can't erase the bootloader on the card, I always have the same error about DLL.



      I uninstall and reinstall softwares and drivers at least 3 times and I tryed on my Linux PC too, same issue.
