Review 5: Atmel SMART SAMA5D4 Xplained Ultra - TCP/IP running

I've blogged about my first steps with the kit, Review 1: Unboxing and First Steps.

The second review was on cross compilation on a Windows machine: Review 2: Building the Libraries from Source

This time I connected the board to my home network.

That wasn't difficult at all.

At first I plugged the network cable from router to board while it had already booted.

The network was detected:

Oct 30 08:29:16 sama5d4-xplained kernel: macb f8020000.ethernet eth0: link up (100/Full)

I didn't get a lease. When I asked linux what my  ip address was, I only got the localhost:

root@sama5d4-xplained:~# ip addr show
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
    link/ether 2a:30:59:a4:17:10 brd ff:ff:ff:ff:ff:ff

A simple reboot with the cable connected gave me an ip address

root@sama5d4-xplained:~# /sbin/ifconfig
eth0      Link encap:Ethernet  HWaddr 96:73:72:46:14:ab
          inet addr:192.168.1.50  Bcast:0.0.0.0  Mask:255.255.255.0

          collisions:0 txqueuelen:0
          RX bytes:700 (700.0 B)  TX bytes:700 (700.0 B)

I was also able to ping other computers in  my network:

root@sama5d4-xplained:~# ping 192.168.1.27
PING 192.168.1.27 (192.168.1.27) 56(84) bytes of data.
64 bytes from 192.168.1.27: icmp_seq=1 ttl=128 time=91.3 ms
64 bytes from 192.168.1.27: icmp_seq=2 ttl=128 time=4.80 ms
64 bytes from 192.168.1.27: icmp_seq=3 ttl=128 time=2.83 ms

and the board shows up on my router's status page

I was able to connect to the board via a browser from another pc. It shows an "It works!" message (see the first picture).

Next Steps:

I couldn't get a telnet or ssh session into the board yet. Putty says "Network error: Connection refused"

I'll have to do some more digging to see how I can get that to work on the distro that's on the board, and what I need to do to get this running.

This may be my next step up in getting my cross-compiled programs installed and running on the linux distro.
