我的 Beaglebone 通过 5V 供电,并通过 PC 上的开放端口连接以太网。我已将这些行添加到 /etc/network/interfaces
auto eth0
iface eth0 inet static
address 192.168.1.80
network 192.168.1.0
netmask 255.255.255.0
这提出了

但是当我尝试 ping 192.168.1.80 时,出现主机无法访问的情况。
即使当我通过串行登录它时,我也会得到

Support/FAQ: http://elinux.org/Beagleboard:BeagleBoneBlack_Debian
default username:password is [debian:temppwd]
The IP Address for eth0 is: 192.168.1.80
The IP Address for usb0 is: 192.168.7.2
我究竟做错了什么?
