Ensuring IP Address Acquisition
After you connect the HPS Ethernet port on the Development Board to
your network and reboot the board, ensure that the board acquires an IP address
successfully.
After you connect the HPS Ethernet port to your network and power up your board,
you should see a solid orange light and a blinking green light. If not, check the
connection of the Ethernet cable to the Ethernet port on your network.
1. To check if your board has an IP address, search for the IP address in boot messages such as the one shown below:
Sending discover...
libphy: stmmac-0:04 - Link is Up - 1000/Full
Sending discover...
Sending select for 137.57.175.148...
Lease of 137.57.175.148 obtained, lease time 86400
/etc/udhcpc.d/50default: Adding DNS 137.57.142.218
/etc/udhcpc.d/50default: Adding DNS 137.57.109.10
/etc/udhcpc.d/50default: Adding DNS 137.57.64.1
done.
The message Lease of <board_IP_address> obtained, lease time 86400 identifies the IP address of the board.
2. If you receive the following output, perform a warm reboot of the board by pressing the WARM button next to the LED lights.
Sending discover...
libphy: stmmac-0:04 - Link is Up - 1000/Full

No lease, failing
The board uses the dynamic host configuration protocol (DHCP) to acquire an IP address. If the session times out waiting for an IP assignment, reboot the CPU to restart the IP acquisition process. To reboot the CPU, press the Warm reset button next to the four HPS LEDs on the board.
3. If you are unable to acquire the IP address, ensure that the Ethernet cable is in good working condition and the Ethernet port on your network is enabled.
