Where can i get any documentations for this (more detailed then just -h) Error code descriptions and so on?
Currently the help info is all that is available. However we have put together detailed documentation for nrfjprog, pynrfjprog, mergehex, that is in the process of being released currently.
Please see in Infocenter (infocenter.nordicsemi.com/index.jsp), nRF Tools section, nRF5x Command Line Tools subsection.
