Creating a custom splash

Our splash screens are generated by writing the raw pixel format directly to the screen. For our touchscreens this is RGB565. To generate this first create a PNG of your logo. You can use ffmpeg either on the board installed from the apt repositories, or from another desktop system. When designing your splash screen keep in mind that it will compress much better in this format when there are solid colors. Our default splash has our logo in the center with a solid black background at 800x480 which is about 3kb. If the file is too large you may have to reformat the disk to expand the size of the initrd.

# Replace image.png with your filename
ffmpeg -vcodec png -i image.png -vcodec rawvideo -f rawvideo -pix_fmt rgb565 splash-800x480

gzip splash-800x480

In the initrd you will find a splash-<resolution>.gz which is loaded automatically on startup. The actual resolution of the PNG should match the size of your display as well. The resolution is varied based on which display you are using:

Baseboard	Resolution
TS-TPC-8390	800x480
TS-TPC-8400	640x480
TS-TPC-8900	800x600
