tvp5150A,Arm11采集图像异常

Other Parts Discussed in Thread: TVP5150A, TVP5150

用tvp5150A采集图像,输出bt656格式,通过6410的camif视频接口采集到dma中,选择输入信号为模拟相机SP-913,参数为

PAL制式
象素 512(H)×582(V)
扫描系统 2:1隔行扫描
扫描频率 水平:15625KHz;垂直:50Hz

硬件连接没有使用AVID,VBLK,FID管脚,直接做悬空处理

5150寄存器配置如下:

{0x00, 0x00},//AIP1A Normal operation
{0x02, 0x70},//set tv mode
{0x03, 0x3d},
{0xc2, 0x04},//yuv enable
{0x0f, 0x1a},
{0x28, 0x04},//palbt601

通过测试程序采集到图像问题如下图,左侧和中间有黑线

不知道哪个环节出了问题,希望ti的工程师或是有过类似经验的大神给予指点,谢谢!
