2 Display Content Based vDRM on Linux

For Linux to display content, it needs to run dispDistSrcLink and DisplayLink on M4 so that the Linux application buffer can transfer to the M4 for display. Use the following steps to run the Linux application:

  1. Run apps.out on Linux terminal.
  2. # press 1 to select the single camera usecase.
  3. # press 8 to select the dispdist usecase.
  4. ctrl+z back to Linux terminal.
  5. Run Linux application.

SDK also provide the fast boot method to run the usecases. Use the following steps to run the usecase:

  1. Change the filesystem script: init-demo.sh (/home/root) :
    1. From LAUNCH_DEMO=0 to LAUNCH_DEMO=1.
  2. Reboot the board, the system can run apps.out automatically.
