I have an Ethernet cable connected to my router. I connected the other end to my laptop and got a successful connection. When I plug it into my Arduino Galileo gen2, even with Ethernet port green light on, I got nothing when I run this:

delay(1000);
system("ifconfig eth0 > /dev/ttyGS0");

This is my output:

eth0      Link encap:Ethernet  HWaddr 00:00:00:00:00:00  
      BROADCAST MULTICAST  MTU:1500  Metric:1
      RX packets:0 errors:0 dropped:0 overruns:0 frame:0
      TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
      collisions:0 txqueuelen:1000 
      RX bytes:0 (0.0 B)  TX bytes:0 (0.0 B)
      Interrupt:41 Base address:0x8000 

What I'm doing wrong?

  • You have no MAC address (HWaddr). This usually means you have a driver problem. That might be why you aren't getting an address. Mar 22, 2017 at 11:48

I really don't know why, but after I initialized the Ethernet interfaceifconfig eth0 up it started working properly. I don't know why this time this command was needed and the others didn't.
