DS90UB964无图像输出

Other Parts Discussed in Thread: ALP

大家好,

          调试964发现无图像输出,开发环境为 ADAS+964+913++sensor,964 和 913 使用同轴电缆连接,目前只接了一个913

          913采用PCLK模式,

          配置好sensor后PCLK HSYNC VSYNC信号都正常,PCLK输出48MHZ,sensor 配置为1280x720 30fps  raw 8bit data输出

但是964无信号输出,读964的状态寄存器:

 964 reg 0x35 = 0x1 说明 TX port pass

 964 reg 0x73= 0x2   line count H

 964 reg 0x74= 0x37   line count L   (0x73,0x74的值一直在变化)
 964 reg 0x75 = 0x2    line length H
 964 reg 0x76 = 0xfd   line length L  (0x75, 0x76的值固定不变)
 964 reg 4d = 0x3
 964 reg 4e= 0x45
964 reg 4f = 0x18 (24MHZ ?)
 964 reg 50= 0x0
 964 reg 55 = 0x0
 964 reg 56= 0x0

说明964接到数据了,可是964没有信号输出,小弟实在毫无头绪,请求各位大神给点建议,谢谢!
