Hailo Quick Start

Getting a build up and running requires two steps:

Install kas — the build tool used by the Hailo BSP.
Download sources and build — clone the meta layer and run kas build.

Step 1 — Install kas

kas is a Python tool that manages Yocto build configurations. Install it with:

pip install kas

Docker is also required to run the build environment.

Step 2 — BSP Sources and First Build

First Yocto Build

Fetch the BSP sources:

git clone https://github.com/hailo-ai/meta-hailo-soc.git -b 1.5.0
cd meta-hailo-soc
git clone https://git.engicam.com/internal/meta-engicam-hailo.git
cp meta-engicam-hailo/kas/hailo15-smarcore.yaml kas/
kas build kas/hailo15-smarcore.yaml

Warning: Some poky recipes are not updated to the last branch. If fetch error occurs please use the command below:

sed -i 's/master/main/g' poky/meta/recipes-extended/cracklib/cracklib_2.9.7.bb
sed -i 's/master/main/g' poky/meta/recipes-graphics/spir/spirv-headers_1.3.204.1.bb
sed -i 's/master/main/g' meta-openembedded/meta-oe/recipes-support/libiio/libiio_git.bb
sed -i 's/master/main/g' poky/meta/recipes-graphics/glslang/glslang_1.3.204.1.bb

Once you finished the first build you can use the Yocto framework as usual:

Es.

source poky/oe-init-build-env

devtool modify linux-yocto-hailo
devtool u.boot
bitbake core-image-minimal
