2.7.5.1. Ensuring IP Address Acquisition

After you connect the HPS Ethernet port on the Cyclone® V SoC Development Kit to your network and restart 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 restart of the board by pressing the WARM button next to the LED lights.
    Sending discover...
    libphy: stmmac-0:04 - Link is Up - 1000/Full
    Sending discover...
    Sending discover...
    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, restart the CPU to restart the IP acquisition process. To restart 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.
