TDA2SX: TDA2XX配置I2C5死机问题

Part Number: TDA2SX
Other Parts Discussed in Thread: AWR2243

Ti工程师您好!我在使用的是AWR2243 Cascade Radar EVM和TDA2xx,使用的SKD包为PROCESSOR_SDK_RADAR_03_08_00_00:我在使用TDA2xx的IPU1_0去控制I2C,根据ti提供的例程能够成功使用I2C2和I2C3,但是同样的代码去控制I2C5时程序会跑死,我通过xds560去调试发现初始化I2C5(函数为lld_i2c_init(&i2cObjHandle,i2c_num,&initPar);)后去打开I2C5(函数为lld_i2c_open(i2c_num,NULL,NULL);)时,在操作I2C5的寄存器(基地址为 0x4807 C000 )时程序就会进入ti的退出例程(__TI_default_exit),无法正常运行。请问这是什么原因造成的。
