Address 0x1a is the WM8904. Address 0x39 is the SIL9022A. I am
not sure what is at address 0x3d and 0x60
14. Networking support via the EMAC 10/100Base-T peripheral can be
added to NSH be selecting the following configuration options.
Remember that only the SAMA5D31 and SAMAD35 support the EMAC
peripheral! This will add several new commands to NSH: ifconfig,
wget, put, get, ping, etc.
14. Networking support via the can be added to NSH be selecting the
following configuration options. The SAMA5D3x supports two different
Ethernet MAC peripherals: (1) The 10/100Base-T EMAC peripheral and
and (2) the 10/100/1000Base-T GMAC peripheral. Only the SAMA5D31
and SAMAD35 support the EMAC peripheral; Only the SAMA5D33, SAMA5D34,
and SAMA5D35 support the GMAC perpheral! NOTE that the SAMA5D35
supports both!

So what can you do with this networking support. First you see that
NSH has several new network related commands:
b) Selecting the GMAC peripheral:
ifconfig, ifdown, ifup: Commands to help manage your network
get and put: TFTP file transfers
wget: HTML file transfers
ping: Check for access to peers on the network
Telnet console: You can access the NSH remotely via telnet.
You can also enable other add on features like full FTP or a Web
Server or XML RPC and others. There are also other features that
you can enable like DHCP client (or server) or network name
resolution.

By default, the IP address of the SAMA5D3x-EK will be 10.0.0.2 and
it will assume that your host is the gateway and has the IP address
10.0.0.1.

You can use ping to test for connectivity to the host (Careful,
Window firewalls usually block ping-related ICMP traffic). On the
target side, you can:
If both EMAC and GMAC are selected, you will also need:

select the KSZ9021/31 PHY for GMAC (See below)
On the host side, you should also be able to ping the SAMA5D3-EK:

nsh> help
help usage: help [-v] [<cmd>]
So what can you do with this networking support? First you see that
NSH has several new network related commands:
[ echo ifconfig mkdir mw sleep
? exec ifdown mkfatfs ping test
cat exit ifup mkfifo ps umount
cp free kill mkrd put usleep
cmp get losetup mh rm wget
dd help ls mount rmdir xd
df hexdump mb mv sh
ifconfig, ifdown, ifup: Commands to help manage your network
get and put: TFTP file transfers
wget: HTML file transfers
ping: Check for access to peers on the network
Telnet console: You can access the NSH remotely via telnet.

You can also enable other add on features like full FTP or a Web
Server or XML RPC and others. There are also other features that
you can enable like DHCP client (or server) or network name
resolution.
NOTE: If you enable this feature, you experience a delay on booting.
That is because the start-up logic waits for the network connection
to be established before starting NuttX. In a real application, you
would probably want to do the network bringup on a separate thread
so that access to the NSH prompt is not delayed.
This delay will be especially long if the board is not connected to
a network.
By default, the IP address of the SAMA5D3x-EK will be 10.0.0.2 and
it will assume that your host is the gateway and has the IP address
10.0.0.1.
