I. Introduction

The meta-on-semiconductor aims to add support for the ON semiconductor camera mezzanine. This meta can be added on top of meta-avnet which adds support for the Ultra96V2.

To use it:

• clone meta-onsemiconductor and meta-avnet repositories in the project-spec/ folder inside your Petalinux project
• in Petalinux config, 'Yocto Settings'/'User Layers', add two layeres '${PROOT}/project-spec/meta-avnet' and '${PROOT}/project-spec/meta-on-semiconductor'. Meta-avnet must have a lower priority than meta-on-semiconductor
• in Petalinux config, change the YOCTO_MACHINE_NAME to use an Avnet Machine ('ultra96v2' for example)
• then you can use 'petalinux-build -c on-semiconductor-image' to build your BSP

You can also clone AVNET's Petalinux git and run the script './scripts/make_onsemi_ap1302.sh' to build the complete Ultra96V2_oob BSP with ON semiconduction camera mezzanine support.

II. Adding the meta-on-semiconductor layer to your build

In order to use this layer, you need to make the build system aware of it.

Assuming the meta-on-semiconductor layer exists at the top-level of your yocto build tree, you can add it to the build system by adding the location of the meta-on-semiconductor layer to bblayers.conf, along with any other layers needed. e.g.:

BBLAYERS ?= "
/path/to/yocto/meta
/path/to/yocto/meta-poky
/path/to/yocto/meta-yocto-bsp
/path/to/yocto/meta-meta-user
/path/to/yocto/meta-avnet
/path/to/yocto/meta-on-semiconductor
"

III. Recipes

meta-on-semiconductor contains one conf folder and multiple recipes: . ├── conf │   └── layer.conf ├── COPYING.MIT ├── README ├── README.md ├── recipes-app │   └── run-1920-1080 ├── recipes-bsp │   ├── ap1302-firmware │   └── device-tree ├── recipes-core │   └── images └── recipes-modules └── ap1302

conf/layer.conf:

Adds the meta-on-semiconductor on top of the meta-avnet.

recipes-app/run-1920-1080:

Installs the script 'run_1920_1080.sh' in the rootfs. This script is used to display the images captured by the cameras on a screen with a resoltion of 1920x1080 at a framerate of 60 fps.

recipes-bsp/ap1302-firmware:

Installs the cameras firmware in the rootfs.

recipes-bsp/device-tree:

Appends the device tree to support the camera mezzanine.

recipes-core/images:

Defines the possible build images based on avnet-minimal-image provided by the meta-avnet.

recipes-modules/ap1302:

Fetches, builds and install the AP1302 kernel module in the rootfs.
