Actions

The page is dedicated to the mixture of Zephyr an RTOS and Tensorflow Micro a subset of the Tensorflow project for Microcontrollers.

Tensorflow as it exists currently doesn't support Zephyr and vise versa so the instructions and code below is a work in progress and not yet pushed upstream.

Howto

This howto is currently specific to the STM32F746ng board.

Download and Setup Zephyr

git clone https://github.com/zephyrproject-rtos/zephyr.git

sudo pip3 install west
sudo pip3 install cmake
install Zephyr SDK
wget https://github.com/zephyrproject-rtos/sdk-ng/releases/download/v0.10.3/zephyr-sdk-0.10.3-setup.run
chmod +x zephyr-sdk-0.10.3-setup.run
./zephyr-sdk-0.10.3-setup.run -- -d /opt/zephyr-sdk
sudo pip3 install -r zephyr/scripts/requirements.txt

export ZEPHYR_TOOLCHAIN_VARIANT=zephyr
export ZEPHYR_SDK_INSTALL_DIR=/opt/zephyr-sdk

cd zephyr
cd zephyr-project

Download tensorflow with experimental zephyr support
git clone https://github.com/tom-gall/tensorflow.git
cd tensorflow
git checkout disco_f746ng_hello

make -f tensorflow/lite/micro/tools/make/Makefile TARGET=zephyr-disco_f746ng hello_world_bin
