HDMI
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.
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 Neutis and launch the application:
qt_hello_world -platform linuxfb
As a result you should see the rendered image.
