SAA7138的视频解码器产生BT656的标清的流，是PAL制式的。输入到DM368，请问能否提供DM368的视频loop-back测试程序。谢谢！！！
很幸运，开发板提供有SD VIDEO loop-back测试程序，你可以填入SAA7138的视频解码程序进去：

谢谢你的答复。我将此程序该成了PAL制式。但是发现VPFE得不到数据。根据
ISIF_CADU = 0x0400; // Frame buffer address high
ISIF_CADL = 0x0000; // Frame buffer address low
设置，我查看了0x04000000处的memory附近的数据，发现根本没任何变化。请问可能是什么原因？
