GPS对EVO授时不成功

外接GPS授时模块，hexdump /dev/miivii-sync-in-a每秒有数据打印出来，cat /dev/ttyTHS1也有GPS的NMEA报文数据出来，MIIVII SETTING里也选择了GPS，但当我修改系统时间，系统时间并没有自动修改回GPS时间

首先修改系统时间的时候要停掉hexdump和cat这两个进程，否则会影响系统授时，其次看一下NMEA数据是否是有效数据，是否含有时间字段，如果无效系统会丢弃，不校时。检查没有问题修改系统时间仍然不校时，请您提供如下信息：
1.ps -ef | grep sync
2.cat /dev/miivii_release
3.dpkg -l | grep miivii
4.是否对设备刷过机，如有请提供刷机工具版本

自己未刷过机，曾经返修过，应该没有刷机

您目前的miivii-autostarter的版本比较老，请做以下操作
1.再次配置miivii_settings中GPS选项
2.确认/opt/miivii/config/sync/sync.cfg文件中sync_type的配置项为0（sync_type:0），如果不是修改为0.
3.重启系统修改系统时间查看
另外提供一下您的系统版本号

修改为GPRMC输出，可以完成时间同步了
