I have CY8CKIT-042 kit, I interfaced External RTC PCF 8583P with I2C interface. It works well. I also Have a kit of CY8CKIT-044. I ported the same program on this kit with interfacing RTC with I2C. But it didn't works. Is any one have any idea that for this new kit any setting need to be altered.

The I2C connection a P4_0 and P4_1 are in use with the -044 kit internally. I would suggest you to use different pins for your connection. Do not forgert the pull up resistors.
