This article explains how to enable third display ie TIVX_TARGET_DISPLAY3, in vision apps. 

  • There are 4 display pipelines supported on J721E/TDA4x. Out of these 4 pipelines, 2 pipelines are supported as standard display targets in the vision apps/tiovx, One pipeline is used to display graphics content. Currently 4th pipeline is not enabled and reserved for the A72 core.

    Attached zip file contains two patchess,

    1. Enable_display3_In_OpenVX.patch: This patch adds third display target TIVX_TARGET_DISPLAY3 in the OpenVX framework. With this patch, three display pipelines can now be attached to three different independent targets, allowing to run display display pipelines. Apply this patch on psdk_rtos_auto_j7_07_00_00_11\tiovx folder.
    2. Enable_display3_In_Vision_Apps.patch: This patch enables remaining display pipeline and connects it to the display controller. Apply this patch on psdk_rtos_auto_j7_07_00_00_11\vision_apps folder.
