This example demonstrates how to enable HDMI support on OES Prime and render the image.
Preparing the image
The first step is to build an image with Qt libraries and hello-world application. If you have not yet
build any images with Yocto, visit this page. If you have already set up build host,
then navigate to OES Prime-image directory.
Open meta-layers/meta-emlid-OES Prime-examples/recipes-core/images/OES Prime-image.bbappend
and uncomment the following line:
IMAGE_INSTALL_append += "qt-example"
qt-example is a Yocto recipe that contains Qt hello-world application and depends on many Qt libraries
which will be compiled and included to the image.
Build the image itself:
source init.sh
bitbake OES Prime-image
Flash OES Prime with the newly created image, boot and log in.
Test
Add HDMI overlay to /boot/Env.txt:
overlays=hdmi
Then reboot and place any picture named image.png in /home/root.
Connect your monitor with HDMI cable to OES Prime and launch the application:
qt_hello_world -platform linuxfb
As a result you should see the rendered image.
