On PicoMOD7 there was the possiblity to enable two framebuffers. So I can draw on one buffer then change the buffers and draw on the other buffer and so on (double buffering to avoid flicker). I tried to change the virtual resolution in kernel configuration to the double height but that ends in error allocating memory for framebuffer.
Resolution: 1024x768x32bit
virt. Resolution: 1024x768x32bit is working but with only one buffer
virt. Resolution: 1024x1536x32bit is not working (s3c-fb s5pv210-fb: failed to allocate display memory)
Is there another way to enable double buffering?
Thanks for help.
