Hi

I have CX3 RDK denobola with OV7251 camera module( RAW 10bit VGA)

I create project and add init code at cyu3imagesensor.c,

Windows can find USB video device and I2c write working good ( I check it with UART)

But it don'y start streaming image.

It always stop at  'AplnStrt:SMState = 0x2' ( it checked at uart)

I also create project with OV5640, but it working very well.

How can i fix it?

Hi,

 

1)Are you using continuous clock or gated clock? If you are using continuous clock , can you please try changing the sensor configuration to gated clock.

 

2)The video will not stream properly if the CX3 MIPI CSI configuration is wrong. Can you please attach the screenshot of your MIPI CSI bridge configuration here so that we can verify the same?

 

3)Attached is the CX3 troubleshooting guide . Please follow the steps mentioned in the same and check if the video is streaming properly.
