TDA4AL-Q1: Use yuv sensor, vision_apps command “p” displays 40000FPS

chang jason

Part Number: TDA4AL-Q1

Using the YUV sensor, after measurement, it was confirmed that the camera CSI 1 has a signal.
But using vision_apps command "p" it shows 40000FPS and then crashes.
Can you provide any debugging guidance?

Hi,

Please ignore the fps for the time being, it seems capture is not working. Capture node's average stats are 0's. Is the camera correctly configured and so is CSIRX?

How can I use the command to confirm the CISRX status?
I have confirmed that CSI is sending signals
The camera configuration has been confirmed with the manufacturer and there is no problem.

Hi,

Can you please refer to below developer note to see why CSIRX is not receiving any frames?
