在video_preview例程想使用ccs 3.3的view中的image来查看图像-TI中文支持网

平台是6437和ccs3.3以下是我的代码：

void main() {

printf("Video Preview Application\n");
fflush(stdout);

sysModuleRegs -> VPSSCLKCTL = (0x18u);

// Reset TVP5151

_waitusec( 800000 );

_waitusec( 800000 );

return;

我在最后的FVID_exchange处设断点想查看frameBuffPtr中的缓存帧但是不成功求指导
