[AkashHemwani]

I want to configure FX3 board to Xilinx FPGA for application AN75779. Is it possible to disable i2c master part from FX3 board and establish direct connection(without any protocol) between fpga and usb board.

If it is possible then what should be approach to disable I2C part.

Hi,

Yes, it should be possible.

Just comment out the sensor writes from the firmware, and set iocfg.useI2C as CyFalse.

Also comment out the I2Cinit API used.

However note that, UVC controls like changing resolution, formats etc would not be possible as you do not have I2C. Also, make sure the image sensor is properly programmed before the AppStart function is executed in the firmware.
