Google Coral Dev Board Yocto Layer

meta-coral-ai

Summary

meta-coral-ai is a yocto layer to support the Google Coral Dev Board.

This layer relies on OpenEmbedded/Yocto build system and depends on:

[OECORE]
URI: https://git.yoctoproject.org/git/poky.git
layers: meta
branch: same dedicated branch as meta-coral-ai

[OE]
URI: https://github.com/openembedded/meta-openembedded.git
layers: meta-oe
branch: same dedicated branch as meta-coral-ai

[FREESCALE]
URI: https://git.yoctoproject.org/git/meta-freescale.git
layers: meta-freescale
branch: same dedicated branch as meta-coral-ai

[TENSORFLOW]
URI: https://git.yoctoproject.org/git/meta-tensorflow.git
layers: meta-tensorflow
branch: same dedicated branch as meta-coral-ai

Build

This layer can be integrated in your layers or built standalone using kas-tool:

kas build kas-coral-ai.yml

or using kas docker container:

kas-container build kas-coral-ai.yml

Flash SD Card

Flash image on a SD Card using bmaptool:

sudo bmaptool copy \
    build/tmp/deploy/images/imx8mq-phanbell/edgetpu-demo-image.wic.gz \
    /dev/mmcX
