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.
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@
command from your development machine.
For instructions on how to identify
section.
2. To transfer files, one at a time, from the host system to the board via SCP, invoke the
scp
command
from your development machine.
Executing an OpenCL Kernel on an SoC
The procedures outlined in this document are for building and running the host application for the
hello_world example design. To execute the hello_world OpenCL kernel on your SoC, you must first
create an
hello_world.aocx
Altera Offline Compiler Executable file. For instructions on obtaining the
hello_world example design and creating the
hello_world.aocx
file, refer to the Creating the FPGA
Hardware Configuration File of an OpenCL Kernel section of the Altera SDK for OpenCL Cyclone V SoC
Getting Started Guide.
Build your host application using the GNU Compiler Collection (GCC) cross-compiler available with the
SoC Embedded Design Suite (EDS).

Building the Host Application
Build your SoC-specific OpenCL host application using the GNU Compiler Collection (GCC) cross-
compiler available with the SoC Embedded Design Suite (EDS).
1. Perform the following tasks to download the hello_world design example.
a. Download the SoC-specific hello_world design example (
from the Hello World Design Example page within the Altera website.
b. Extract
exm_opencl_hello_world_arm32_linux_
to a location to which you have write
access.
c. Ensure that you set the environment variable AOCL_BOARD_PACKAGE_ROOT to point to the
Cyclone V SoC Development Kit Reference Platform (that is,
%ALTERAOCLSDKROOT%\board\c5soc
).
2. At a command prompt, invoke the following command to set the PATH environment variable:
SET PATH=%PATH%;
3. Navigate to the
directory.
4. Invoke the
make -f Makefile
command. Alternatively, you can simply invoke the
make
command.
