Gonk

Getting Started

  1. Clone the repo

    git clone https://pigweed.googlesource.com/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
    

Capture ADC samples and plot

  1. First bootstrap, run pw build and flash gonk using DFU.

    . ./bootstrap.sh
    
    pw build
    

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

    Run gonk-flash on the MCU binary. This uses pyfu-usb.

    gonk-flash ./out/gn/arduino_size_optimized/obj/applications/gonk/gonk.bin
    
  2. Start capturing ADC samples with:

    gonk \
      --bitstream-file DEFAULT \
      --log-to-stderr
    
    • Press Enter to stop or start ADC continuous updates. It will begin automatically on startup.
    • Press ctrl-c to quit.
  3. Plot the logs from gonk-csv-log.txt with:

    python tools/gonk_tools/plot.py -i gonk-csv-log.txt -o plot.svg
    

Compilation Details

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 Build

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

sudo apt install fpga-icestorm nextpnr-ice40 yosys

Running pw build will run the FPGA toolchain if these commands are available on the $PATH:

  • icepack
  • icetime
  • nextpnr-ice40
  • yosys

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 Firmware Build

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

Flash via DFU

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

  2. Run gonk-flash which uses pyfu-usb. The --bin-file argument is optional.

    gonk-flash --bin-file ./out/gn/arduino_size_optimized/obj/applications/gonk/bin/gonk.elf
    

Alternative: Flash with BlackMagic Probe

This is more useful if you are doing firmware debugging.

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

Generating the Gonk Python Bundle

This is a distibutable python wheel that can be used without the Gonk source checkout or compiling anything.

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.

GPIO assert events in the CSV

When GPIOs are pulled LOW (to ground) a line in the CSV will appear with delta_micros = 0 and empty measurement values. The Comment field will contain the GPIO assert log message.

Example:

Compiling the FPGA Toolchain

yosys

See https://github.com/YosysHQ/yosys for more instructions.

On Ubuntu/Debian install the deps:

sudo apt-get install build-essential clang lld bison flex \
    libreadline-dev gawk tcl-dev libffi-dev git \
    graphviz xdot pkg-config python3 libboost-system-dev \
    libboost-python-dev libboost-filesystem-dev zlib1g-dev

Activate the bootstrap environment . ./bootstraph.sh then compile yosys.

git clone https://github.com/YosysHQ/yosys
cd yosys
git submodule update --init
make config-clang
make -j8

Install it to a known directory and add it to your $PATH:

make DESTDIR=$HOME/ice40-fpga-tools install
export $PATH=$PATH:$HOME/ice40-fpga-tools/usr/local/bin
