DART-MX8M-MINI e-con Systems Camera

Introduction

The instructions on this page add e-con Systems MIPI cameras support to Yocto images for Variscite i.MX8M and i.MX8MM platforms.

Download the Variscite Yocto BSP

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

Download and install the e-con meta layer

$ wget ftp://customerv:Variscite1@ftp.variscite.com/E-Con/econ-4.14.98.tar.gz
$ tar xf econ-4.14.98.tar.gz
$ mv econ-4.14.98/meta-econ-imx8 ../sources

Download and install the appropriate Variscite kernel patches

$ wget ftp://customerv:Variscite1@ftp.variscite.com/E-Con/sumo-fsl-4.14.98/recipes-kernel/linux.tar.gz
$ rm -rf ../sources/meta-variscite-imx/recipes-kernel/linux
$ tar xf linux.tar.gz -C ../sources/meta-variscite-imx/recipes-kernel

Adjust the relevant Yocto configuration files

Edit bblayers.conf

Add the following lines to conf/bblayers.conf

BBLAYERS += " ${BSPDIR}/sources/meta-econ-imx8 "

Edit local.conf

Add the following to conf/local.conf under your Yocto build directory:

Add the e-con Systems camera driver:

MACHINE_ESSENTIAL_EXTRA_RDEPENDS += "kernel-module-econ-camera-driver"

Add the relevant device tree files to the build:

KERNEL_DEVICETREE_append_imx8mq-var-dart = " \
        freescale/fsl-imx8mq-var-dart-sd-dp-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-sd-hdmi-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-sd-lvds-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-sd-lvds-dp-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-sd-lvds-hdmi-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-wifi-dp-econ-camera.dtb \

        freescale/fsl-imx8mq-var-dart-wifi-lvds-dp-econ-camera.dtb \
        freescale/fsl-imx8mq-var-dart-wifi-lvds-hdmi-econ-camera.dtb \
"

KERNEL_DEVICETREE_append_imx8mm-var-dart = " \
        freescale/fsl-imx8mm-var-dart-econ-camera.dtb \
        freescale/fsl-imx8mm-var-som-econ-camera.dtb \
        freescale/fsl-imx8mm-var-som-econ-camera-rev10.dtb \
"

Build a Yocto image

Continue following Build Yocto from source code from where you left off to bitbake and install a Yocto image.

Testing the e-con Systems camera

Follow DART-MX8M CSI to test the camera.
