am335x 设置静态ip（/etc/network/interface）设不了

你贴的这段没有将dhcp注释掉啊

参考一下这个：
auto lo
iface lo inet loopback

allow-hotplug wlan0
iface wlan0 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan1
iface wlan1 inet manual
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf

allow-hotplug wlan0
#iface wlan0 inet dhcp
iface wlan0 inet static
address 192.168.0.110
netmask 255.255.255.0
network 192.168.0.1
gateway 192.168.0.1
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
#iface default inet dhcp


iface eth0 inet static
address 192.168.0.115
netmask 255.255.255.0
network 192.168.0.1
gateway 192.168.0.1
