This wiki provides step-by-step guidance for compiling an image specifically for the Hailo-15 device.

Step 1: Install Required Packages

To get started, run the following command to install the necessary dependencies:

sudo apt install python3-pip chrpath diffstat gawk zstd lz4 kas

Make sure you have administrative privileges to execute this command successfully.

Step 2: Clone the git repository

Next, clone the Git repository and navigate to the release folder by executing the following commands:

git clone https://github.com/hailo-ai/meta-hailo-soc.git 

cd meta-hailo-soc

This will create a local copy of the repository and change your working directory to the meta-hailo-soc folder.

Step 3: First-Time Build

To initiate the first-time build and configure the default environment, run the following command:

kas build kas/hailo15-evb.yml

The .yml file specifies the target board for the build.

Note: This command only needs to be run once.

Step 4: Source the Build Environment

To set up the build environment, execute the following command:

source poky/oe-init-build-env

This command will prepare the necessary environment variables for the build process.

Step 5: Compile the image

To compile the image, use the following command with BitBake:

bitbake core-image-minimal

Or, if you only want to compile the kernel, you can run:

bitbake linux-yocto-hailo

Or if you want to compile the full development image, you can run:

bitbake core-image-hailo-dev

Building the Yocto Image for the Hailo-15-SBC

If you're building the Yocto image for the Hailo15-SBC, ensure you configure the correct target machine by following these steps:

1. Navigate to Your Yocto Project

Go to the root directory of your Yocto project.

2. Modify the Configuration File

Open the local.conf file located in the /build/conf directory.

3. Change the Target Machine

Locate the line that specifies the machine configuration:

MACHINE ??= "hailo15-evb-security-camera"

Change it to:

MACHINE ??= "hailo15-sbc"

4. Save and Exit

Save the changes to the local.conf file and exit your text editor.

5. Recompile the project

Return to Step 5 in this wiki to recompile your project with the new target machine.
