VCC3V3 测量到是3.3V，MIPI_CK_N 时钟是固定的吗？时钟是多少的？设置帧率后这个时钟会变吗？

@veye_xumm
排线长度有26厘米长

@veye_xumm
内核打印的信息显示datarate是1.5G，用示波器测量不到时钟波形，只能测到数据波形，这个模块的实际datarate是多少的？现在抓图的时候，内核驱动报crc错误，怀疑是排线太长或者datarate对不上。

读取相机的datarate返回是-1代表什么意思。

执行指令结果如下：
873ce878-1078-4470-9adb-eb9d860562c4-企业微信截图_17326077017593.png
硬件是有转接板的，量过了线序是对应的上的：

取图时的信息和dmesg信息如下：
