关于 load3536 脚本执行出错的问题

开发板：hi3536
SDK：Hi3536 V100R001C02SPC50


执行命令：

/mnt/mpp_single/ko # ./load3536 -i

输出信息：

在文件 tlv320aic31.c 中有：

static int i2c_client_init(void)
{
    struct i2c_adapter *i2c_adap;

    // use i2c2
    i2c_adap = i2c_get_adapter(0);
    if (NULL == i2c_adap)
    {
        printk("find i2c adapter fail. \n");
        return -1;
    }
        tlv_client = i2c_new_device(i2c_adap, &hi_info);

        i2c_put_adapter(i2c_adap);

    return 0;
}

表示获取 i2c 适配器失败了，不知道是不是与 i2c 相关的管脚复用没有配置好？谢谢！
