Gonk

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.

Gonk Verilog:

The Verilog build requires the following to be installed on Linux:

sudo apt install fpga-icestorm nextpnr-ice40 yosys

Run this to compile:

pw build

The bitstream files will be written with the .bin extenson under ./out/gn/obj/fpga/*/*.bin along with log output files.

For example:

$ ls ./out/gn/obj/fpga/toplevel/
nextpnr-log.txt
toplevel.asc
toplevel.bin
toplevel.json
toplevel_timing_report.json
toplevel_timing_report.txt
yosys-log.txt

Gonk fpga config Example

Flash the stm32f7 and launch the write_fpga.py script on a bitstream file.

Flash with dfu-util

  1. Unplug gonk from USB and replug with MODE button held down.

  2. Run pw flash on the MCU binary.

    pw flash ./out/gn/arduino_size_optimized/obj/applications/fpga_config/fpga_config.bin

Write the FPGA bitstream

  1. Write an FPGA bitstream with the write_fpga.py script:

    python ./tools/gonk_tools/write_fpga.py \
  --bitstream-file ./out/gn/obj/fpga/toplevel/toplevel.bin
  --database ./out/gn/arduino_size_optimized/obj/applications/fpga_config/bin/fpga_config.elf \
  --log-to-stderr

    You can redirect host and device logs to separate files with:

    python ./tools/gonk_tools/write_fpga.py \
  --bitstream-file ./out/gn/obj/fpga/toplevel/toplevel.bin
  --database ./out/gn/arduino_size_optimized/obj/applications/fpga_config/bin/fpga_config.elf \
  --host-logfile gonk-host-logs.txt \
  --device-logfile gonk-device-logs.txt

Alternative: Flash with BlackMagic Probe

./scripts/flash-with-blackmagic-probe.sh ./out/gn/arduino_size_optimized/obj/applications/spi_flash_test/bin/spi_flash_test.elf

Generating the Gonk Python Bundle

On Linux with the FPGA toolchain available run:

pw build

The zip file containing all the dependencies for the gonk python tooling is located in:

out/gn/obj/gonk_bundle.zip

Inside are the Python wheels for gonk_dist, gonk_firmware, and all third_party dependencies.

pw_system Example

Run on 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

Run 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
