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.
3. 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.
5. 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.
