MX8 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/video from a Basler camera(s) connected to Variscite evaluation platforms.
You can save the camera output to a storage device and process it 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.
