Part Number: PROCESSOR-SDK-AM335X

Tool/software: Linux

Created an SD card with the pre-built SDK. When in /etc/network/interfaces, eth0 interface is described as:

auto eth0

iface eth0 inet dhcp

System works correctly (beagle bone is able to get an ip address from the dhcp server of the network and I can see it by typing ifconfig; it is 192.168.1.17).

However, when I change the description for a static ip addres as below:

auto eth0

iface eth0 inet static

address 192.168.1.20

netmask 255.255.255.0

ifconfig still shows the address assigned by the dhcp server, I.e. 192.168.1.17

(I was hoping to see

Hi Teklike,

Did you try ifconfig eth0 down and ifconfig eth0 up ?

Hi Dwarakesh, Thanks for the suggestion.

That did not help.

Thinking on similar lines I issued, "/etc/init.d/networking restart". This brought up the eth0 with the correct static ip address.

Since the interface works with DHCP correctly, it does not seem this suggestion would help

Hi Teklike,

Couple of suggestions
1. Have you tried adding "allow-hotplug eth0" in /etc/network/interfaces ?
2. Would suggest to add /etc/init.d/networking start or /etc/init.d/networking restart in one of rcS files.
