Hi3518EV300（liteos）添加驱动AR0144报ISP没有初始化问题

在海思3518EV300添加AR0144sensor，回调函数
HI_S32 cmos_init_sensor_exp_function(ISP_SENSOR_EXP_FUNC_S *pstSensorExpFunc)
{
   CMOS_CHECK_POINTER(pstSensorExpFunc);
    memset(pstSensorExpFunc, 0, sizeof(ISP_SENSOR_EXP_FUNC_S));

    pstSensorExpFunc->pfn_cmos_sensor_init = ar0144_init;
    pstSensorExpFunc->pfn_cmos_sensor_exit = ar0144_exit;
}
运行sample_venc后，报：get ar0144 sensor global init
============== sensor_register_callback  sucess!

请问什么问题导致？加调试信息没有触发回调函数ar0144_init
