9 Multi Camera VPAC Application Demo

  • The demo application runs on powerON and images can seen on the eDP/HDMI display simultaneously from all four cameras.
  • The images are such that the camera streams 1000 frames at 30FPS.
  • In the UART terminal, you should see the login prompt as shown below:
    j7-evm login:
  • On the EVM, Login using the below user id, no password.
    root
  • On the EVM, do the following steps to view the logs for the demo application.
    cd /opt/vision_apps

source ./vision_apps_init.sh
  • The following logs confirm that the completion of the demo applications on the R5F core are successful.
