We are now using CYUSB3KIT-003 + ov5642 to capture camera video but failed, there is no data frame from the kit to PC. The sensor is configured OK, the OSC shows normal waveforms of sensor signals. And the IED sometimes shows "Quit (expect signal SIGINT when the program is resumed)" when debugging.
In the snapshot, I see that there are not even a single frame captured by the FX3. Please do check for PROD event in the DMA callback as well.
If the sensor is npt driving the FV/LV correctly, then the GPIF will not sample the data. Please use the CyU3PGpifGetSMState API in the application thread for loop and continuously print this value over UART. Please check if the GPIF is going into the IN_Data state. If the GPIF does not go to the in_Data state, then the GPIF will never capture the data. In this case, you need to check the interfacing signals.
