Please let me know why did you keep h blanking and v blanking field as 0. Because from the line valid trace the h blanking is not zero.
You need to configure the CX3 receiver settings according to the sensor output.
Please let us know the sensor output
Can you probe the sensor output (not from CX3 test pins) and share the traces (FV LV and PCLK)
The CX3 configuration utility should be in sync to the sensor output.The CX3 configuration utility should be exactly configured as the sensor output. Any mismatch in these two will cause improper streaming of the video (imporper FV and LV on CX3 test points). can you probe these test points on CX3? In the previous reply you mentioned the FV is from the CX3 test point
After proper initialization of mipi communication the gpif state machine samples the video data as per the FV and LV. The CX3 has a fixed GPIF state machine which is similar to GPIF state machine mentioned in AN75779 application note https://www.cypress.com/documentation/application-notes/an75779-how-implement-image-sensor-interface-using-ez-usb-fx3-us…
what is the hsync trigger start time and end time on cx3 side?
>> this would depend on the CX3 configuration utility settings and output from sensor.
If sensor output is not same as configuration utility settings there can be problem in FV, LV generation. It would be helpful to get the traces of sensor output.
