MX8 Basler Camera NXP
Introduction
The following instructions will allow you to add support for the Basler MIPI camera to your Yocto images using the software modules already present in the Yocto BSP.
This will allow you to stream images/video from a Basler camera(s) connected to a Variscite evaluation kit.
Available cameras
- VCAM-AR1335B (daA4200-30mci): not supported
- VCAM-AR0821B (daA3840-mc): supported
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.
Customize configuration files
Customize local.conf
Add the following to conf/local.conf under your Yocto build directory:
IMAGE_INSTALL_append_mx8mp = " \
kernel-module-isp-vvcam \
isp-imx \
basler-camera \
"
Build Yocto image
Continue following Build Yocto from source code from where you left off, to bitbake and install an image.
Preparing Yocto to use the Basler camera
The Yocto image supports the standard camera by default. In order to use the Basler camera an additional step is needed. Run the following commands at the shell prompt:
# cd /boot # mv imx8mp-var-dart-dt8mcustomboard.dtb imx8mp-var-dart-dt8mcustomboard-ov5640.dtb # mv imx8mp-var-dart-dt8mcustomboard-legacy.dtb imx8mp-var-dart-dt8mcustomboard-legacy-ov5640.dtb # mv imx8mp-var-som-symphony.dtb imx8mp-var-som-symphony-ov5640.dtb # ln -fs imx8mp-var-dart-dt8mcustomboard-basler-isp0.dtb imx8mp-var-dart-dt8mcustomboard.dtb # ln -fs imx8mp-var-dart-dt8mcustomboard-legacy-basler-isp0.dtb imx8mp-var-dart-dt8mcustomboard-legacy.dtb # ln -fs imx8mp-var-som-symphony-basler-isp0.dtb imx8mp-var-som-symphony.dtb
Running GStreamer
Run the following command at the shell prompt:
