I am trying to use the framebuffer driver on a SAM9G35. I would like to double buffer the display but when I use FBIOPAN_DISPLAY I can still see the redraw. I tried a simple example which flips between a red and blue fraembuffer every second however when the flip happens I can see horizontal tearing. Is this supported or is there a differnt ioctl I should be using?
