GEX Firmware for STM32F072

This is the STM32F072 GEX firmware, supporting all STM32F072 GEX boards (including the F072 Discovery).

Links

GEX repositories are mirrored on GitHub to make it easier to submit issues and propose improvements via "pull requests". Please use the upstream repository when cloning to ensure you have the latest version of the code. The mirrors are kept up-to-date, but they may fall behind.

git.ondrovo.com/gex/gex-f072 - upstream (F072)
git.ondrovo.com/gex/gex-core - upstream (GexCore submodule)
github.com/gexpander/gex-f072 - GitHub mirror (F072)
github.com/gexpander/gex-core - GitHub mirror (GexCore submodule)

Building the Firmware

Make sure you clone the repository recursively (git clone --recursive ...), or run git submodule update --init afterwards, to initialize the GexCore submodule.

In order to build the firmware, first copy the configuration file template build.mk.example to build.mk, modify as desired, then run make to build the binary image (see the Make Targets section below for more options).

Individual GEX units can be enabled or disabled in build.mk, and the target platform (your GEX board model) is selected here as well. The config file is excluded from version control.

Requirements

Listed versions were used during development. Other (particularly newer) versions may work too, but without a guarantee. Please submit patches needed to fix incompatibilities, or at least let me know.

arm-none-eabi-gcc (v8.1)
arm-none-eabi-binutils (v2.30)
arm-none-eabi-newlib (v3.0)
make (GNU, v4.2)
tr (GNU coreutils 8.29 - but any version should work)
dfu-util (v0.9) for DFU flashing
stlink (texane, v1.5) for ST-Link flashing

Make Targets

make - basic build (recommended to use with -j for faster builds)
make flash - flash using st-flash
make dfu - flash using dfu-convert and dfu-util
make clean - clean files generated during build

All make targets depend on all Makefiles, meaning any modification triggers a full (-B) rebuild the next time you try to build or flash the firmware.
