ARM provides .exe installers for Windows. Grab one from here, and follow the instructions. Just before the installation process finishes tick/select the "Add path to environment variable" option. Then verify that the tools are in your %PATH%:

$ arm-none-eabi-gdb -v
GNU gdb (GNU Tools for Arm Embedded Processors 7-2018-q2-update)


There's no official binary release of OpenOCD for Windows but if you're not in the mood to compile it yourself, the xPack project provides a binary distribution, here. Follow the provided installation instructions. Then update your %PATH% environment variable to include the path where the binaries were installed. (C:\Users\USERNAME\AppData\Roaming\xPacks\@xpack-dev-tools\openocd\0.10.0-13.1\.content\bin\, if you've been using the easy install)

Verify that OpenOCD is in your %PATH% with:

$ openocd -v
Open On-Chip Debugger 0.10.0


Grab QEMU from the official website.

ST-LINK USB driver

You'll also need to install this USB driver or OpenOCD won't work. Follow the installer instructions and make sure you install the right version (32-bit or 64-bit) of the driver.

That's all! Go to the next section.
