Screen Board Support for TI J722s: Release Notes

A screen support package contains the display and GPU libraries and drivers needed to extend the general base screen package for a particular board support package (BSP). For compatibility, all three support packages: board, base screen, and extended screen support, should be based on the QNX Software Development Platform 8.0 (SDP 8.0).

QNX SDP is a cross-compiling and debugging environment, including an IDE and command-line tools, for building binary images and programs for ARM v8 and x86_64 targets running the QNX OS 8.0.

Throughout this document, you may see reference numbers associated with particular issues or changes. When corresponding with our Technical Support staff about an issue, use the relevant reference number. You might also find the reference numbers useful for tracking issues as they become fixed.

To access the most up-to-date version of these release notes, go to the QNX Software Center, right-click on the Screen Board Support for Screen Board Support for TI J722s package, choose Properties, and use the link provided.

Package version

This package contains the display and GPU libraries and drivers to support the SDP 8.0 base screen package when used with board support package (BSP): QNX SDP 8.0 BSP for Texas Instruments J722S Evaluation Module.

This screen board support package, and the base screen package it has been validated with are:

Board support

The following platform is supported in this update:

Known issues

• Vulkan and OpenCL apps fail with an unknown symbol error when the following package is installed: com.qnx.qnx800.target.microkernel.core (versions 2.0.3 and earlier). (Ref# 2980748)
• The graphics-virtual-dpy.conf references rgx-alloc, but the binary isn't shipped as part of the package. Workaround: To fix the configuration, update the following lines in the graphics-virtual-dpy.conf file from:

                      begin globals
                      blit-config = gles2blt
                      alloc-config = rgx-alloc
                      end globals
                  

  to:

                      begin globals
                      blit-config = gles2blt
                      alloc-config = jacinto7-alloc
                      end globals
                  

BSP Integration

Add the following libraries and binaries to the BSP buildfile to add base graphics capabilities to your BSP (doesn't include input or video capture):
