CC9M tetris example problem

Hi to all, I am a newbe with CC9M and I am trying to follow the quick start guide istructions…so I’ve created a new file system with Qt libs to be able to launch correctly the tetris example but still have a problem…it seems to be a frame buffer problem…the fb lib is also present but the program doesn.t start…can someone explain me (step by step) how can I correct configure the system for the tetris example?
Thanks in advance, regards
