edgeai-tiovx-modules

Repository to host TI's OpenVx modules used in EdgeAI SDK.

Dependencies

This OpenVx modules are validated only on TDA4VM/J721E/J7ES board using EdgeAI image built using PSDK-LINUX and PSDK-RTOS

These modules are used by edgeai-gst-plugins https://github.com/TexasInstruments/edgeai-gst-plugins/

Steps to clone and build on target

clone the repo under '/opt'

/opt# git clone https://github.com/TexasInstruments/edgeai-tiovx-modules.git

Compilation on the target

The library can be built directly on the target as follows.

/opt# cd /opt/edgeai-tiovx-modules
/opt/edgeai-tiovx-modules# mkdir build
/opt/edgeai-tiovx-modules# cd build
/opt/edgeai-tiovx-modules/build# cmake ..
/opt/edgeai-tiovx-modules/build# make -j2

Installation

The following command installs the library and header files under /usr dirctory. The headers and library will be placed as follows

/opt/edgeai-tiovx-modules/build# make install

The headers and library will be placed as follows

• Headers: /usr/include/edgeai-tiovx-modules/
• Library: /usr/lib/

The desired install location can be specified as follows

/opt/edgeai-tiovx-modules/build# cmake -DCMAKE_INSTALL_PREFIX=<path/to/install> ..
/opt/edgeai-tiovx-modules/build# make -j2
/opt/edgeai-tiovx-modules/build# make install

• Headers: path/to/install/include/edgeai-tiovx-modules/
• Library: path/to/install/lib/

Cross-Compilation for the target

The library can be cross-compiled on an x86_64 machine for the target. Here are the steps for cross-compilation. Here 'work_area' is used as the root directory for illustration.

cd work_area
git clone https://github.com/TexasInstruments/edgeai-tiovx-modules.git
cd edgeai-tiovx-modules
# Update cmake/setup_cross_compile.sh to specify tool paths and settings
mkdir build
cd build
source ../cmake/setup_cross_compile.sh
cmake -DCMAKE_TOOLCHAIN_FILE=../cmake/cross_compile_aarch64.cmake ..
make -j2
make install DESTDIR=<path/to/targetfs>

The library and headers will be placed under the following directory structire. Here we use the default '/usr/' install previx and we prepend the tarfetfs directory location

• Headers: path/to/targetfs/usr/include/edgeai-tiovx-modules/
• Library: path/to/targetfs/usr/lib/
