Hi Cypress Experts:
I am trying connect camera with ISP to CX3, but no image output.
The ISP output MIPI setting as below:
The CX3 configuration as below:
Could you please help to check whether there is anywhere un-reasonable?
Here is the log:

Hi,
Please increase the minimum vertical blanking period of sensor so that CX3 has enough time to wrapup the last buffer of a frame partially full.

Hi,
Can you confirm whether your ISP is working in continous clock mode or gate mode? If it is in continous clock mode, can you switch it to gate mode and try again?

Hi Eddie and Cypress Expert;
Thanks for your reply,
I can get frame by changed the reset setting.
Now I have another issue, the camera input is 30fps, but CX3 output only 15fps.
Here is the probe wave of Hsync and Fsync:
And the log as below:

Hi,
This issue is casued by the interval between two Vsync pluse is too short. You can try to increase that interval.

Hi Yiz:
Thanks a lot for your reply.
Could you please educate me more about how to fix this?
Increase the Vsync blanking of CX3 MIPI? Or Increase the V-blanking of sensor input to CX3 ?
Thanks
