起動後、eth1インターフェイスに静的IPアドレスを設定する必要があります。ただし、起動時にデバイスは常に/etc/network/interfacesに設定されているIPアドレスとは異なるIPアドレスを持ちます。これはBeagle BoneのLinuxオペレーティングシステムです。
私のビーグルボーンでは、次のLinuxバージョンを使用しています。
root@beaglebone:/etc/network# cat /proc/version
Linux version 4.4.54-ti-r93 (root@a4-imx6q-wandboard-2gb) (gcc version 4.9.2 (Debian 4.9.2-10) ) #1 SMP Fri Mar 17 13:08:22 UTC 2017
ファイルは/etc/network/interfaces以下のようになります。
##connman: WiFi
#
#connmanctl
#connmanctl> tether wifi off
#connmanctl> enable wifi
#connmanctl> scan wifi
#connmanctl> services
#connmanctl> agent on
#connmanctl> connect wifi_*_managed_psk
#connmanctl> quit

ifconfigの出力は次のとおりです
