MX8 Basler Camera

DART-MX8M Basler Camera

Introduction

The following instructions will help you to integrate Basler MIPI camera support into Variscite Yocto images for i.MX8M and i.MX8MM platforms. This will allow you to stream images from a Basler camera(s) connected to Variscite evaluation platforms. You can save the images to storage device and process them using the Basler pylon SDK and the pylonViewer app.

Download Variscite Yocto BSP

Please follow Build Yocto from source code
Execute steps 1-4.3 to download the BSP sources, but don't start bitbake yet.

Download and install Basler meta layers

$ tar xf basler-dart-bcon-mipi-imx8-cep_1.1.2.tar.gz -C sources

Download and install Variscite kernel patches

$ wget ftp://customerv:Variscite1@ftp.variscite.com/Basler/sumo-fsl-4.14.98/recipes-kernel/linux.tar.gz
$ mv sources/meta-variscite-imx/recipes-kernel/linux sources/meta-variscite-imx/recipes-kernel/linux.orig
$ tar xf linux.tar.gz -C sources/meta-variscite-imx/recipes-kernel

Customize configuration files

Customize bblayers.conf

Add the following lines to conf/bblayers.conf

BBLAYERS += " ${BSPDIR}/sources/meta-basler-imx8 "
BBLAYERS += " ${BSPDIR}/sources/meta-basler-tools/meta-basler-common "

Customize local.conf

Add the following lines to conf/local.conf to add Basler software and driver

IMAGE_INSTALL_append = " \
