Can you try typing:


“ifconfig –all” – and see if eth1 appears in that list?


If it does, try:


“sudo ifconfig eth1 up”

“sudo dhclient eth1”


...If that works, you can make the change permanent by editing /proc/network/interfaces (google for syntax or copy what’s there).

Subject: [Gumstix-users] eth1 not working in Gumstix


Hi All,


I have tried to design an expansion board which is exactly similar to the Tobi-Duo in its schematics (and also has 2 ethernet ports).


I built a very simple kernel image comprised of from an online builder ( 


During run-time, when I try 'ifconfig -a', I am shown two connections - 'eth0' (this one works completely fine) and 'lo' (Link encap: Local Loopback .......). Although I expect eth1 to appear, it does not. 


I am pretty sure that the hardware of the expansion board is fine because I noticed that if I use an online standard kernel image downloaded from, both eth0 and eth1 do work! However, I would rather not use such a bulky kernel for a simple task of mine.


Why is the eth1 not initialized/ready? I would appreciate any suggestions to help me solve this issue.


Thanks! Have a cheerful day :)
