nrfjprog error code 9

[Cyril Hruscak]

Hi,

during programming, we receive error as in this question. The hex files do not overlap.

It seems to happen only when the board has already been programmed before (but also here not always, just sometimes).

What could cause the error?

which version of nrfjrpog are you using? in command prompt type "nrfjprog -v" (without the quotes).

If it is not 8.3.0 then update it and see if this problem still exists?
