In the following video we showcase an assymetric application showing interaction between real-time and multimedia activities through OpenAMP:

• On Cortex A7
  • We run a Linux kernel and rootfs generated using System Workbench for Linux
  • We capture images from the camera using gstreamer
  • We analyze it using OpenCV to detect the number of fingers raised
  • We display the camera output and the analysis output in a graphical interface built with QT
  • Depending on the fingers configuration, we send speed and direction orders to the Cortex-M4 through OpenAMP
• On Cortex M4
  • We receive speed and direction orders from the Cortex-A7 through OpenAMP
  • We control a motor, using two timers of the Cortex-M4 configured to generate PWM control signals to the motor
