Introduction
demo for g2d usage.
Building for Linux
-
Install Yocto SDK under /opt
For example, installed 5.10-hardknott to /opt/fsl-imx-internal-xwayland/5.10-hardknott
-
Setup build environment
source /opt/fsl-imx-internal-xwayland/5.10-hardknott/environment-setup-aarch64-poky-linux
Configure build for G2D implementation
export BUILD_IMPLEMENTATION=dpu
export BUILD_IMPLEMENTATION=dpu95
export BUILD_IMPLEMENTATION=gpu-drm
export BUILD_IMPLEMENTATION=gpu-fbdev
export BUILD_IMPLEMENTATION=pxp
- Build
DESTDIR=/opt/rootfs make clean
DESTDIR=/opt/rootfs make install
- Run, test availability depends on BUILD_IMPLEMENTATION

The jpg file can be found on the Internet, just make sure the resolution is correct. Prepare the 1024x768-rgb565.rgb, 800x600-bgr565.rgb, 480x360-bgr565.rgb, 352x288-yuyv.yuv, 352x288-nv16.yuv, 176x144-yuv420p.yuv with below cmd.
$ffmpeg -i 1024x768.jpg -pix_fmt rgb565le 1024x768-rgb565.rgb
$ffmpeg -i 800x600.jpg -pix_fmt bgr565le 800x600-bgr565.rgb

$./g2d_overlay_test
-s source's width and height
-d dest's width and height
-w line stride of source and dest, bytes unit.
$./g2d_yuv_test -s 1024x768 -d 1024x768 -w 1024x1024 -i PM5544_MK10_YUYV422.raw -f yuyv-yu12
Building for QNX
- Setup build environment
source /qnx700/qnxsdp-env.sh
- Build
make -f Makefile.qnx
- Run
$./g2d_basic_test
$./g2d_multiblit_test
$./g2d_overlay_test
See instruction for linux how to build source files with image data.
Additional Notes:
- There is no source distribution available for Android BSPs. The driver requires specific integration into the Android OS and is not available as a separate source package.
