I2C issues on CY7C68013A

I am using Cy3684 to test my code. I am writing following code to write some data on lg eeprom, but it doen't seem to work. i also tried tweaking function definition inside i2c.c provided by cypress. I am attaching my keil code here, and the edited i2c.c. I am checking SCL SDA lines using a DSO, but there is no fluctuation. Whereas when a burn iic file to lg eeprom using cyconsole i get fluctuations on SCL SDA lines.

 

//main code to write data to eeprom. The data is any dummy data, but it should write.

#include <fx2.h>
#include <fx2regs.h>
#include "i2c.c"

void main(void)
{
