We provide two applications, fbtest and fbsaver, that directly write to the framebuffer device. You can use these applications to check whether your target's framebuffer is working correctly.
First download the package, and then run the following commands to extract the package (which will create the directory Framebuffer within your current working directory) and install all necessary files on the target:
# tar xzf Framebuffer.tgz # Framebuffer/install-target.sh 192.168.3.11
Replace 192.168.3.11 with the actual IP address of your target. (The Board Support Packages provided by PHYTEC use 192.168.3.11 by default.)
Now you can run /usr/local/Framebuffer-Demos/fbtest or /usr/local/Framebuffer-Demos/fbsaver on your target.
If you want to remove all files that were installed by install-target.sh, invoke the following command:
# Framebuffer/uninstall-target 192.168.3.11
