  • Dear Pig,

    Could you let us know which board you are testing with ? Which Jlink version is installed on your PC ? have you installed the lastest one (and make sure the firmware on the JLink programmer is updated) ?

    If you flash simple application such as blinky example (without softdevice), would it work ?

    Could you try to use nrfjprog tool to program (and recover if needed) ?
