HI3520D DRQCV100 sample_vio 绑定vpss出错 谢谢各位，努力学习中

首先感谢各位于百忙中解答，非常感谢，新手请多照顾。

板子启动后，使用./sample_vio 0会直接报错。查看源码是在SAMPLE_COMM_VO_BindVpss函数中出错
错误信息如下：
./sample_vio 0
[SAMPLE_COMM_SYS_CalcPicVbBlkSize]-167: w:768, u32AlignWidth:64
start vo SD1.
u32Width:720, u32Square:1
start vo HD0.
u32Width:1024, u32Square:3
HDMI start success.
start vo SD0: wbc from hd0
u32Width:720, u32Square:1
please choose preview mode, press 'q' to exit this sample.
        0) 1 preview
        1) 4 preview
        2) 8 preview
        q) quit
1
[SAMPLE_VIO_8_D1]-615: vo(0) switch to 4 mode
u32Width:1024, u32Square:2
[SAMPLE_VIO_8_D1]-640: Start VO failed!
[SAMPLE_COMM_VO_StopDevLayer]-151: failed with 0xa00f8048!
program exit abnormally!

但是如果拿SDK中编译的sample_vio运行，报错的地方不一样
./huawe_vio 0
[SAMPLE_COMM_SYS_CalcPicVbBlkSize]-167: w:768, u32AlignWidth:64
start vo SD1.
[SAMPLE_COMM_VO_StartDevLayer]-99: failed with 0xa00f8010!
[SAMPLE_VIO_8_D1]-432: SAMPLE_COMM_VO_StartDevLayer failed!
program exit abnormally!

在板子自带的驱动ko文件夹中加载3520D的驱动，会报有的驱动已经存在，开机时，根据输出日志，应该是已经加载部分驱动了。

如果使用sdk的ko加载驱动，报的错误不是特别不一样，难道我下载的sdk版本不对么？那个sdk写的也是3520dv100.
