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
iface usb0 inet static
address 192.168.7.10
netmask 255.255.255.0
network 192.168.7.0
gateway 192.168.7.1
EOF
# Add terminal to virtual serial port
cat >/etc/init/gadget-serial.conf <<EOF
start on stopped rc RUNLEVEL=[2345]
stop on runlevel [!2345]
respawn
#exec /sbin/getty 115200 ttyGS0
exec /sbin/getty 9600 ttyGS0
EOF
# Write script to start gadget driver
cat >/usr/sbin/g-multi-load.sh <<'EOF'
#!/bin/bash
if [ "`lsmod | grep g_multi`" != "" ]; then exit 0; fi
mac_addr=/proc/device-tree/ocp/ethernet@4a100000/slave@4a100300/mac-address
eeprom=/sys/bus/i2c/devices/0-0050/eeprom
DEV_ADDR=$(perl -e 'print join(":",unpack("(H2)*",<>))' ${mac_addr})
VERSION=$(perl -e '@x=unpack("A12A4",<>); print $x[1]' ${eeprom})
SERIAL_NUMBER=$(perl -e '@x=unpack("A16A12",<>); print $x[1]' ${eeprom})
ISBLACK=$(perl -e '@x=unpack("A20A4",<>); print $x[1]' ${eeprom})
BLACK=""
if [ "${ISBLACK}" = "BBBK" ] ; then
BLACK="Black"
fi
if [ "${ISBLACK}" = "BNLT" ] ; then
BLACK="Black"
fi
modprobe g_multi file=/dev/mmcblk0p1 cdrom=0 stall=0 removable=1 nofua=1

Thanks!!
