Hi,

I am getting issue in installing nrfutil in windows.

the PATH is not properly installed.

is there any solution for it.

[bjorn-spockeli]

Can you elaborate? If you've downloaded the .exe from https://github.com/NordicSemiconductor/pc-nrfutil/releases, then you need to add the path where you placed the .exe file to the windows path. 

[Sunil vignesh]

Yes,

Can you tell me exactly how to set the PATH.

I am not well in python.

[Carl Richard]

You can either write export <path_to_executable> in your terminal or follow the instructions for editing environment variables(including PATH) found(for example) here.

Good luck!

[Sunil vignesh]

My Query is have i Windows 10. I have download the nrfutil.exe from here.

While i run the exe file, within a few seconds the exe file closed.

During this i have not installed any version of Python.

After that I have installed Python 2.7.12

but running the CMD and enter python it when to store to install Python 3.7

I am not understanding.

Is that DFU secure bootloader need

Ubuntu / Linux OS support?
