Edge Impulse Example: stand-alone inferencing (Himax WE-I Plus)

This runs an exported impulse on the Himax WE-I Plus development board. See the documentation at Running your impulse locally (Himax WE-I Plus).

How to build (Linux)

Metaware Toolkit

1. Install the DesignWare ARC MetaWare Toolkit and make sure ccac is in your PATH. You'll also need a valid ARC MetaWare license.

2. Create a build directory and initialize CMake:

   $ mkdir build-mw
   $ cd build-mw
   $ cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.metaware.cmake ..
   

3. Build and link the application:

   $ make -j
   $ sh ../make-image.sh MW
   

GNU

1. Install the GNU Toolchain for DesignWare ARC processors and make sure arc-elf32-gcc is in your PATH.

2. Create a build directory and initialize CMake:

   $ mkdir build-gnu
   $ cd build-gnu
   $ cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.gnu.cmake ..
   

3. Build and link the application:

   $ make -j
   $ sh ../make-image.sh GNU
   

How to build (any other operating system using Docker)

Metaware Toolkit

1. Note that you'll need a valid ARC MetaWare license to build.

2. Build the container:

   $ docker build -t himax-build -f Dockerfile .
   

3. Then set up your build environment:

   $ mkdir -p build-mw
   $ docker run --rm -it -v $PWD:/app himax-build /bin/bash -c "cd build-mw && cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.metaware.cmake .."
   

4. And build and link the application:

   $ docker run --rm -it -v $PWD:/app:delegated -e [email protected] himax-build /bin/bash -c "cd build-mw && make -j && sh ../make-image.sh MW"
   

   Where you'll have to replace [email protected] with your license server or license file.

GNU

1. Build the container:

   $ docker build -t himax-build-gnu -f Dockerfile.gnu .
   

2. Then set up your build environment:

   $ mkdir -p build-gnu
   $ docker run --rm -it -v $PWD:/app himax-build-gnu /bin/bash -c "cd build-gnu && cmake -DCMAKE_TOOLCHAIN_FILE=toolchain.gnu.cmake .."
   

3. And build and link the application:

   $ docker run --rm -it -v $PWD:/app:delegated himax-build-gnu /bin/bash -c "cd build-gnu && make -j && sh ../make-image.sh GNU"
   

Flashing the binary

You'll need the Edge Impulse CLI. Then flash the binary with:

$ himax-flash-tool --firmware-path image_gen_linux/out.img
