Default address of MBR3 is 0x37,
*Did you modify I2C slave address?
*Are there any other devices on the Bus in your board?
*Ensure that Ez-Click is configuring the right device , which is MBR3.
Thanks for the reply. Yes. I figured out what was wrong. The CY8CMBR was not soldered properly, which resulted in the device not being detected during scan of all available devices. And, there was another device onboard, which was with 0x18. It took me a while to figure that the SW was detecting the other device and not MBR. A rework on the solder solved the problem and I was able to program successfully!!
how i interface cy8cmbr3106 with pic controller over i2c
