Screen Board Support for NXP i.MX93: Release Notes

Package contents

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.

Notes

This revision adds support for the PHYTEC phyBOARD-NASH-i.MX93 BSP. The BSP integration setup does not change for the NXP i.MX93, while additional changes (step 3) should be made for use with the PHYTEC board.

There are no new known issues with this revision of screen support for the i.MX93. Existing and fixed issues from across i.MX93 releases can be found in the combined Issues log section of this release note.

Issues log

This log lists all tracked issues QNX has reported from past and current releases of the i.MX93 screen support package. To see if an issue applies to the Screen release package you are using, refer to the Found-in and Fixed-in columns for your issue. This will provide the range of released build IDs where the issue may occur. Any issue with a Fixed-in entry of open is unresolved in the most current official release (the top-most build listed).


Reference	Issue and Workaround	Found-in	Fixed-in
J2963008	Blitting a surface with a global alpha (SCREEN_BLIT_GLOBAL_ALPHA) other than 255 may generate incorrect results. Workaround: None available.	Build 126	open
J2961325, J2956296	The PXP 2D engine can only do one operation at a time: blending, scaling, or rotation (flip). You can't combine these operations. Workaround: This issue is due to a hardware limitation, so no workaround is available.	Build 126	open

For common QNX Software Development Platform issues that may impact your BSP or screen support, see the QNX Software Development Platform 8.0 Release Notes website.
