I have two ARM target boards

How do I configure 2 such boards running Linux (Busybox) to communicate over Ethernet (pc to pc communication) with each other ?

Can this be done using PC-to-Hub CAT-5 cables or do I necessarily need PC-to-PC / cross-connected cable ?

I tried with both the cross as well straight cables, I do not see LAN card link blinking, is there any configuration changes for Ethernet card that I need to do here ?

If I try an connect one board to a PC both the ends can ping each other perfectly.

TIA

Did you set IP addresses from the same subnet? Did you use the crossover cable between the two PCs? Yes between PCs you have to use crossovers. Are the interfaces UP? –  Ashtray Aug 6 '13 at 6:25
    
Without knowing what Network interface is built-in to your board, it is basically impossible to answer this. Are you sure your cross-over cable is good? –  Zoredache Aug 6 '13 at 6:25
    
@Alex Yes the IP were on same subnet, I tried both crossover as well straight cables. –  Bleamer Aug 6 '13 at 6:28
    
What happens if you do create traffic, e.g. "ping 255.255.255.255"? –  Marcel Waldvogel Aug 6 '13 at 6:29
    
@Zoredache I am certain that the cable is good, since the same works between two desktop PCs correctly. –  Bleamer Aug 6 '13 at 6:29
