    Hi,

     

    Its recommended to use nRF connect programmer for programming nRF5-series devices, as nRFgo Studio isn't maintained anymore.

    Q1: Is this a problem on one specific device, or does this occur on all devices that you try to program?

    Q2: Have you tried to use JLink Commander, and what was the output from that?

    Q3: Have you ever been able to program this device, or did this happen "after some time" while developing?

    Kind regards,

    Håkon

    JLink Commander seems to be able to connect successfully, you can try to read out the memory using "mem32 0,100", which will read the first 100 words in flash.

    What version of nrfjprog are you using? If it is old, then that might be the problem.

     

    Kind regards,

    Håkon
