Building From Source

This project is cross-compiled on an x86 Ubuntu Linux system. However other similar Linux-base systems (or a Linux virtual environment on another OS) can likely be made to work quite easily.

The Ubuntu package prerequisites include:

• git
• gcc-arm-none-eabi
• stm32flash
• zip

If the stm32flash package is unavailable on your system then it must be downloaded from Sourceforge and built locally.

To install the prerequisites on Ubuntu:

 # sudo apt install git gcc-arm-none-eabi stm32flash zip

To build the FF OSD firmware:

 # git clone https://github.com/keirf/FF_OSD.git
 # cd FF_OSD
 # make dist
