选择“3”,显示如下:

Network Menu
    1. Display parameter
    2. Modify parameter
    3. Save parameter
    4. Download file
    0. Return


继续操作,选择“4”,显示如下:

Enter your choice(1-4):4
Download file to: [ 1:flash 2:sd1 ]:2
Check SD Card[1] file system. Please wait....
SD Card check Fail! Please FORMAT SD Card first.


从上面的显示信息中看出SD卡初始化失败了,可能是由于运输导致SD卡虚插导致。尝试将主控板拔出,插拔SD卡,问题解决。

建议与总结
经常会有设备由于运输过程中导致SD卡或者内存条虚插,可以查看设备的打印信息来判断是SD卡或者内存条虚插。如果虚插了,拔插一下即可解决问题。
