DS90UB936-Q1: ds90ub936外接ds90ub933后, ds90ub936的CSI端,用示波器测量无信号输出

Part Number: DS90UB936-Q1


ds90ub936外接ds90ub933后, ds90ub936的CSI端,用示波器测量无信号输出, 但进行Pattern Generator测试是可以看到画面,

下面为读取到的DS90UB936  端的寄存器,

其中:

0x4d  是0x03  已经LOCK

0x6d  是0x7F 

通过I2C透传后,可正常获取到DS90UB933寄存器数据, 用示波器量DS90UB936  但csi没有看到任何数据输出 ,会是什么原因
