Are you connecting the ethernet cable directly between your computer and the board?
Or are you using a router?
Either way, you need to find out the IP of the board. That will no longer be 192.168.7.2. As mentioned above
giuliomoro There are programs that allow you to discover devices on a network which you could use for this, or usually routers have a configuration page that allows you to see the connected devices.
I often found the home router to be on 192.168.0.1 or 192.168.1.1, however sometimes it may be on 10.0.0.1, sometimes it's something entirely different. Or you could get a better idea by looking at your computer's network properties. You will find that your IP address is something like (.g."xxx.yyy.zzz.www") and the router is probably xxx.yyy.zzz.1.
You could try to load one of these pages on your browser and see if anything shows up. If it requires a password, that is probably printed on the back of the router. Once you are logged in you should be able to see IP addresses of the connected devices somewhere. I think the Bela will show up as "BELA" or "BEAGLEBONE".
If the above does not work you want you can also try to brute force pinging the Beaglebone over the network. Find out the "xxx.yyy.zzz.www" IP of your computer and try to ping anything from "xxx.yyy.zzz.2" to "xxx.yyy.www.254" except your own computer. This will probably successfully ping other devices on your network, including e.g.: your mobile phone, but one of those will be the Bela.
This will do:
XXXYYYZZZ=192.168.0 #replace with your own subnet
TIMEOUT=1 # time to wait for each device to respond
for a in {2..255}
do ADDR=$XXXYYYZZZ.$a
printf .
ping -t $TIMEOUT $ADDR &> /dev/null && printf "\nFound a device on $ADDR\n"
sleep 0.1
done
the above works on Mac, you may have to adjust the parameters to ping
if you are on a different system.
Once you find an address that responds, try to load that in the browser, or you can try to ssh into it:
ssh root@THEADDRESS
if that address indeed was Bela, you should be welcomed by the Bela logo.
If you want to run the Bela scripts for an address different from the default one, you can see here.
