    这个错误是串口通信校验错误，M30上订阅TOPIC暂请不要超过10个，且波特率尽量设置高一点。

    在samples/sample_c/platform/linux/nvidia_jetson/application/dji_sdk_config.h中只定义了数据传输功能如下：

    #define CONFIG_MODULE_SAMPLE_DATA_TRANSMISSION_ON

    执行可执行文件./dji_sdk_demo_linux还是报错：

    具体运行信息如下：

    Start dji sdk application后不打印任何东西是正常的执行逻辑。
