可以通过板卡上的reset键重启板卡，不过系统是起来了，网卡还在睡觉，打着双闪，要彻底断电冷启才能恢复

另外一个命令就是shutdown关闭，似乎也不能达到预期

不知道为什么，几次测试下来，彻底断电网卡也不灵了，先去吃饭，回来再看

[FAILED] Failed to start Raise network interfaces.

See 'systemctl status networking.service' for details.

又搞不定网卡了，先进行其它测试吧，板卡直连电脑可以协商到10M网络，

设置电脑ip为192.168.18.18

设置板卡ip为192.168.18.100

ifconfig eth0 192.168.18.100

ping 192.168.18.18 -c 4

USB测试用的USB读卡器，应该识别成U盘吧，不太如意，稍后再研究吧，可以了

换上TF卡，不是自弹插槽，第一次用

然后可以挂载

mount /dev/mmcblk0p1 /mnt

好啦《MY-IMX6-EK140_Linux-4.1.15_测试手册》的内容基本过完，继续磕网卡吧

谢谢分享经验

今天我也准备跑一遍这个测试手册
