problem of use IIC Moudle in a DSP/BIOS program on DM642

Started by X.Y. September 1, 2006
In order to config on board codecs using IIC moudle (support by CSL
API)  in a DSP/BIOS program, I add a IIC write sentence behind video
mini driver's configuration for a simple test like this:

    FVID_control(disChan,
    			 VPORT_CMD_EDC_BASE + EDC_CONFIG,
                 (Ptr)&EVMDM642_vDisParamsSAA7105);

	addrI2C = 0x88 >>1;
	for(i =0; i<43; i++)
	{
			_IIC_write(hmydm642i2c,
					   addrI2C,
					   (sa7121hNTSC[i].regsubaddr),
					   (sa7121hNTSC[i].regvule));
         }

However, it stop at the sentence "I2C_bb" all the time, what's the
reason of this situation?
