QNX SDP 8.0 Screen Board Support Xilinx Kria Board Series: Release Notes

Screen support packages contain 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 the 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 8.0 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.

BSP Integration

Perform the following steps to add base graphics capabilities to your BSP (doesn't include input or video capture):

1. Add the following libraries to the BSP build file:

   /lib/dll/screen-zynq-alloc-kria.so=screen-zynq-alloc-kria.so
   /lib/dll/screen-zynq-alloc.so=screen-zynq-alloc.so
   #########################################################################
   # Board Specific graphics files for Xilinx KRIA KR260 or KV260 targets
   #########################################################################
   
   /usr/lib/graphics/kria/graphics.conf=graphics/kria/graphics.conf
   /usr/lib/graphics/kria/libmali-kbase.so=graphics/kria/libmali-kbase.so
   /usr/lib/graphics/kria/libmali.so=graphics/kria/libmali.so
   /usr/lib/graphics/kria/libwfdcfg-kria.so=graphics/kria/libwfdcfg-kria.so
   /usr/lib/graphics/kria/libWFDzynq-kria.so=graphics/kria/libWFDzynq-kria.so
                       

2. Add the following binaries and configuration files to the BSP build file:

   $BUILDFILE_BINS_CONFIGS
   #######################################################################
   ## Start the screen graphics
   #######################################################################
   [perms=0755] /scripts/graphics_start.sh = {
   #!/bin/sh
   LD_LIBRARY_PATH=/lib:/usr/lib:/lib/dll:/lib/dll/pci:/proc/boot:/usr/lib/graphics/kria
   PATH=/sbin:/bin:/usr/sbin:/usr/bin:/opt/sbin:/opt/bin:/proc/boot
   
   echo "Starting screen"
   sleep 6
   screen -c /usr/lib/graphics/kria/graphics.conf
   waitfor /dev/screen
   
   }
                       

3. At the being of the build file in the .bootstrap section you will update the LD_LIBRARY_PATH to include the /usr/lib/graphics/kria location, by adding in the text in bold.

   [+keeplinked] PATH=/proc/boot:/bin:/usr/bin:/sbin:/usr/sbin: LD_LIBRARY_PATH=/proc/boot:/lib:/usr/lib:/lib/dll:/usr/lib/graphics/kria procnto-smp-instr -v
