Getting Started

  1. Clone the repo

    git clone https://pigweed.googlesource.com/pigweed/gonk
    
  2. Source bootstrap.sh to download all compilers and tooling into the environment directory:

    . ./bootstrap.sh
    

    This should init all git submodules for you.

  3. From here on the Pigweed environment is activated. You can activate the environment in a new shell without re-running bootstrap by sourcing activate.sh

    . ./activate.sh
    

Compile:

Build for the host and device by running:

pw build

This is mostly a shortcut with nice output for running gn gen out/gn and ninja -C out/gn.

The build commands are defined in: //tools/gonk_tools/build_project.py.

Run:

Host

Run the host app and connect to it via pw-system-console:

./out/gn/host_device_simulator.speed_optimized/obj/applications/system_example/bin/system_example & \
  pw-system-console --socket-addr default \
    --proto-globs third_party/pigweed/pw_rpc/echo.proto ; \
  killall system_example

On device

Flashing

openocd -s $PW_PIGWEED_CIPD_INSTALL_DIR/share/openocd/scripts \
  -f $GONK_ROOT/targets/stm32f769i_disc0_stm32cube/openocd_stm32f7xx.cfg \
  -c "program out/gn/stm32f769i_disc0_stm32cube.size_optimized/obj/applications/system_example/bin/system_example.elf reset exit"

Updating STM32Cube

Checkout the desired commits in each of these submodules:

third_party/stm32cube_f7/cmsis_core
third_party/stm32cube_f7/cmsis_device
third_party/stm32cube_f7/hal_driver

Then run from Gonk root:

python -m pw_stm32cube_build gen_file_list third_party/stm32cube_f7
