Hi!
I’ve been trying to change the static IP on my BBB’s usb0 interface, but even though I’ve changed the entry in the /etc/network/interfaces file as well as the usb0 IP address as set in the uEnv on the boot partition, my BBB insists on taking the default IP of 192.168.7.2. What’s going on?
Here’s the modified boot config file, which is found in scripts/setup-ubuntu-armhf-3…ne30.sh:
#!/bin/bash
Update /etc/network/interfaces to add virtual Ethernet port
cat >>/etc/network/interfaces <<EOF
