TDA4VM: Assign static IP address to eth0

Part Number: TDA4VM

Hi,

I want to assign a static IP address to my device. Here's my process:

1- vi /etc/network/interfaces

2- Change the following

# Wired or wireless interfaces
auto eth0
#iface eth0 inet dhcp
#        pre-up /bin/grep -v -e "ip=[0-9]\+\.[0-9]\+\.[0-9]\+\.[0-9]\+" /proc/cmdline > /dev/null
#        udhcpc_opts -R -b
iface eth0 inet static
	address aa.bb.cc.dd    # not actual
	netmask aa.bb.cc.dd    # not actual
	network aa.bb.cc.dd    # not actual
	broadcast aa.bb.cc.dd  # not actual

3- reboot

I would have thought that this would be sufficient, but it seems not. What am I missing?
