Hi Rinat, Unfortunately we don’t currently have any display drivers available. In the past we’ve developed a simple bga (Bochs Graphics Adaptor) driver to use with qemu. But that is quite simple and doesn’t reflect what you’d need for a real graphics adaptor. Ihor.

Students of our AOS course have had success getting HDMI on the sabre lite[1] platform working in the past. The sabre lite is also our verification target platform, so is worth considering. Cheers, Anna.

Next build some widget applications that allow you do something useful or interesting. Next graft the minimal graphics layer onto seL4. Yes you need a tty to type on. Next build a proof model and revise the above as needed. This gives you three+ tasks much of which can be run in parallel. With a BeagleBone you can let it boot to a text window and "type" startx. Your system could have "startWidget" script. Do map out what basic display is. As a minimum you need the equivalent of get_pixel and put_pixel. Modern boards like the BBB and Raspberry-Pi have graphics co-processors. Their basic feature set is not a frame buffer model. Look for VGA features. -- T o m M i t c h e l l
