Hi, 

I am trying to connect the OV8865 camera sensor to the e-con CX3 Denebola board.  The I2C seems to through an error 74: "CY_U3P_ERROR_FAILURE,/**< Failure due to a non-specific system error. */". The MCLK and the voltages have been verified satisfactorily. Please do guide me on what the problem could and how it can be rectified.

Can you please make sure that the pull up resistors are connected on the I2C lines?

Which API returns CY_U3P_ERROR_FAILURE error? Is it CyU3PMipicsiInit or sensor configuration?

If it is while configuring the sensor can you please check if the sensor address is set correctly?

Thank you for the response...

> Yes, the pull up resistors have been connected on the I2C lines.

> The CY_U3P_ERROR_FAILURE error is not returned on  CyU3PMipicsiInit - it is returned on I2C calls: CyU3PI2cTransmitBytes and CyU3PI2cReceiveBytes.

> Yes, the sensor addresses have also been verified.
