What causes it?,MIPI Configured in the attachment。thanks

You need to check the return value of API CyU3PMipicsiSetIntfParams(). CX3 should output PCLK signal ater the corresponding configuration bytes are sent.

In addition, you could invoke CyU3PMipicsiQueryIntfParams to read back the values to check if they are what you expect.

Looks like the host could not get the correct description information or could not install the corresponding driver for your device. Check the USB steup control with USB analyzer or BUS HOUND and share the results.

thanks you for reply!

   Now my MIPI data line has signal output. see attachment;,but  my cx3's  pixclk is no signal,vsync  is high level,hsync is low level.

1. The screenshot shows the MIPI output signal reaches different amplitude. I am not very sure if the signal is correct. Try to capture the wavform with another oscilloscope which has bandwith and resolution.

2. Connact the sensor vendor to check if you have send correct parameters to sensor.

3. Please refer to the link below.

sensor 输出信号是正确的,现在cx3 pixclk没有信号,上位机接收不到

Sensor output signal is correct. Now cx3 pixclk has no signal and the host computer can not receive it.

Why does my cx3 pixclk have no signal? Is this necessary?

I think my Cx3 is not well configured. Can you help me configure it?

Here is my sensor output configuration:

CSI clk = 243           

Data lane = 4

THS_prepare = 57.69

THS_zero = 237.98

PCLK (ref) = 96Mhz

H active =2592

H blanking = 16

V active = 1944

V blanking = 54

Data format = RGB8

REFCLK = 19.2

Are you refering to pin H8(PCLK) of CX3 in this reply? Do you mean that you could not observe any output on this pin?
