使用的是
tisk-rootfs-image-am437x-evm.tar.xz这个镜像
修改了etc/network/interfaces配置eth0为静态IP，脚本内容如下：
# interface file auto-generated by buildroot auto loiface lo inet loopback auto eth0iface eth0 inet static address 172.16.214.199 netmask 255.255.254.0 gateway 172.16.214.1
但是每次重启后eth0都未被配置为设定的IP，使用ifconfig eth0查询得到如下信息
eth0 Link encap:Ethernet HWaddr A8:1B:6A:57:49:9C
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:76 errors:0 dropped:0 overruns:0 frame:0
TX packets:5 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:6902 (6.7 KiB) TX bytes:1670 (1.6 KiB)
Interrupt:143
需要手动使用ifup -a命令手动配置后静态IP才起作用
root@am437x-evm:~# ifup -a
root@am437x-evm:~# ifconfig
eth0 Link encap:Ethernet HWaddr A8:1B:6A:57:49:9C
