If you want to design an embedded linux graduation project, please give me some suggestions. Thank you.

If you want to do a graduation design in Embedded linux, I would like to give you a suggestion. Thank you-general Linux technology-Linux programming and kernel information. For more information, see the following. I now have an arm9-development Board (mini2440) with a touch screen and a camera. I want to use it for my graduation project. However, I don't know what to do. The tutor said that the selection should be practical and meaningful. I want to develop the QT or driver, but I still don't think about the specific content. Please give me some suggestions. Thank you very much! Any suggestions are acceptable, not necessarily QT or driver. Thank you.
