Hi,

If you do not have nrfjprog set up you can follow these steps.

Download and install the command line tools executable.

Open the command line and type:

nrfjprog --help

This will list the different input parameters and other help documentation. If the command line reports that it cannot find the program follow the instructions below in Adding PATH Variables.

Adding PATH Variables

Sometimes nrfjprog.exe will not be added to PATH by default, this is how to do it manually. If you are looking for more information on what the PATH variable is, please consult this answer at Superuser.

In windows 7 (for other systems consult the link above) navigate to environment variables by:

Pressing: Win+Break

Then click on Advanced system settings
Click on Environment Variables...

Add the variable to path by clicking the Edit... button

Then add nrfjprog by adding ´;C:\Program Files (x86)\Nordic Semiconductor\nrf5x\bin´ to the end of the variable value for PATH. Make sure that you add a ; between entries in PATH values, i.e. path1;path2.

Then press OK. Now you will be able to see the help dialog when you type nrfjprog --help in a new command line.

Best regards,

Øyvind

You can do this with

nrfjprog --family nrf52 --recover
