I tried various methods either using Qt (eglfs and wayland) or egl directly, but I can't disable vsync/swapinterval 0/single buffer. Does this board support disabling vsync? As mentioned before I tried several methods, but here's a specific example. I downloaded the PowerVR SDK and cross compiled the beginner example, 02_IntroducingPowerVRShell. I then copied the program to the board and ran it, but couldn't disable vsync.
