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?
