Build RIOT on Windows OS

This page documents a brief description about building RIOT on Windows OS. There is no special build trick for RIOT so default build system settings for arm cross compilers will be described for Windows Operating Systems.

1- Installing ARM GCC Toolchain

• Download installer from here and start the installation.

• Please select a path (Destination Folder) without spaces: e.g. "C:/armgcc"

  

• Select "Add path to environment variable"

2- Installing MinGW and MSYS

• Download MINGW from here and start installation. Please select short paths without spaces for MinGW directory: e.g. c:\MinGW

and now click "Apply Changes" under "Installation" Menu.

• Find mintty under "C:\MinGW\msys\1.0\bin" and create a Desktop shortcut. And right click on the desktop shortcut, select "Properties" and change target to "C:\MinGW\msys\1.0\bin\mintty.exe /bin/bash -l"

3- Build environment is ready now. Build your RIOT application.

**4- Flashing On some platforms RIOT uses OpenOCD for flashing the nodes. Although, OpenOCD does not support Windows officially, they do provide a link to some Windows binaries of their flashing tool. You can find the link at the OpenOCD homepage.
