This example demonstrates how to enable HDMI support on Neutis 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 neutis-image directory.

Open meta-layers/meta-emlid-neutis-examples/recipes-core/images/neutis-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 neutis-image

Flash Neutis with the newly created image, boot and log in.


Add HDMI overlay to /boot/Env.txt:


Then reboot and place any picture named image.png in /home/root. Connect your monitor with HDMI cable to Neutis and launch the application:

qt_hello_world -platform linuxfb

As a result you should see the rendered image.
