ARM compiler

You should download it from GNU-RM Downloads. On Ubuntu/Any Linux Distribution

wget https://developer.arm.com/-/media/Files/downloads/gnu-rm/9-2019q4/RC2.1/gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2

tar xjf gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux.tar.bz2

This will create the following directory on your current directory:

gcc-arm-none-eabi-9-2019-q4-major-x86_64-linux

Add /gcc-arm-none-eabi-5_2-2015q4/bin to your $PATH.

Windows

GNU-RM Downloads has a downloadable installer for the GCC ARM compiler, make sure after you install it is on your PATH, if not add it.

Uniflash

Insall TI's Uniflash tool for your operating system. This tool allows you to upload the built firmware to the CC1312R.

You can download Uniflash here.

Building

The build process is very simple, just call make and it will build the firmware and then put it under the build/simplelink/.

make TARGET=simplelink BOARD=launchpad/cc1312r
