yields no errors but the LED does not blink.
Same for
```
/opt/nrfjprog/nrfjprog family NRF52 program ./BUILD/NRF52_DK/GCC_ARM/mbed-os-example-blinky.hex
```
It does not matter if I do a power cycle, press any of the buttons.
Flashing via the filesystem does work.
So I assume that either I am missing a commandline switch which must be not obvious or something different I am not aware of.
Can anyone shed some light on this?
