Did you look at the scope to see the clock? Is the clock distorted? 
Did you try to run I2C in low clock rate?

I work on a 5501 with the DSP as master on I2C. Here's my code for setting
things up in master mode.
I hope it can give you some help, as I'm not familiar enough with things to
know how all details work out.

The problems I had when setting things up was that my transfer rate didn't
match the rate of the component with the lowest transfer rate. Also I had to
set two registers by
myself, as they were not included in the I2C_Setup structure. (not sure if
it's the correct way to do it, but it works for me)
Good luck!
-------------------------------------
/* Create and initialize an I2C initialization structure */
I2C_Setup initStructI2C =
{
0, /* 7 bit address mode */
0x0000, /* own address - don't care if master */
SYSCLK2_FREQ, /* Slow Peripherals (Mhz)*/
100, /* Transfer rate in kbps, 10-400. Use max 100 kbps, RTC is the limiting
factor.*/
0, /* number of bits/byte to be received or transmitted (8)*/
0, /* DLB mode off*/
1 /* FREE mode of operation on*/
};
void initTLDI2C()
{
/* Initialize I2C, using parameters in initI2C structure */
I2C_setup(&initStructI2C);
//Divide low
perPortRegSet(0xFF,0x3C03);/* I2C clock low divider register, IO mapped*/
//Divide high
perPortRegSet(0xFF,0x3C04);/* I2C clock high divider register, IO mapped */
}

//and for write I use (example): I2C_write((Uint16*)
timeI2CRTCArray,9,1,0x68,1,30000);

Hi 
I don't see anything on Scope.No clock.No data. Even when running CSL
sample code for C5502!

Dear sima
Thank you very much.
I got some signal out of I2c !! :)

Good Luck

Grats!
Glad I could help =)
