Integrating ov7251 sensor on jetson nano

Hello,
I am trying to integrate ov7251 sensor in jetson nano 4GB SDK. From the available user manual of sensor, I was able to compile the module successfully. The sensor is supporting linux version >=5 where jetson nano’s tegra version is 4.9 so I had to modify few lines in code to make it successfully compile and run. I am getting the node /dev/video and in lsmod the ov7251 driver installed.

In order to verify the sensor connection, I am trying to read on i2c at address 0x60. But I am not getting anything. It seems like sensor is not being detected. Can anyone have any idea what can be the issue or what should be the next debugging steps?

Your immigiate attention would be really helpful.

Thanks,
Vidhi V.

For i2c failed ack could be the sensor incorrect state of power/reset/stand_by pins.
