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.

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 hard processor system (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.

Mounting a Shared Drive

The most convenient way to share files between a development PC and the Cyclone V SoC development

board is to mount a network drive.

1. Check the /etc/fstab file systems table file on your development PC for the line that describes the

mounting of the drive you want to use on the board.

The following example /etc/fstab entry indicates that the /data folder on the my_nas server is mounted

to the /data folder on the development PC:

my_nas:/data /data nfs

exec,dev,suid,rw,tcp,hard,intr,vers=3,rsize=32768,wsize=32768,timeo=600,retrans=200

2. Add the /etc/fstab entry described above to the /etc/fstab file on the Cyclone V SoC development board.

Run the sync command to save the /etc/fstab file to the SD flash card.

4. Create an empty folder on the board that serves as the mounting point for the network drive.

For example: type mkdir /data, where /data is the name of the folder.

Invoke the busybox mount -a command.

If the mounting operation fails, rerun the command.

Using SSH and SCP

Instead of connecting the Cyclone V SoC Development Kit to the host system using UART over USB and

transferring files using a network drive, you can initiate a Secure Shell (SSH) connection and transfer files

using a Secure Copy (SCP) program.

1. To establish a connection between the Cyclone V SoC Development Kit and the host system via SSH,

invoke the ssh root@<board_ip_address> command from your development machine.
