world\bin

directory.

Running the Host Application

To execute the

hello_world.aocx

Altera Offline Compiler Executable file on the SoC, run the host

application you built from the ARM-specific

Makefile

.

1. Log into your SoC board.

2. Copy the

hello_world.aocx

hardware configuration file and the hello_world host executable from the

<exm_opencl_hello_world_arm32_linux_<version>>\hello_world\bin

to the board.

3. Ensure that the LD_LIBRARY_PATH environment variable includes the

$%ALTERAOCLSDKROOT%\host\

arm32\lib

.

4. To execute the kernel on the SoC, at a command prompt, navigate to the host executable directory and

run the hello_world host executable.

Output from Successful Kernel Execution on the Cyclone V SoC Development Kit

When you run the host application to execute your OpenCL kernel on the Cyclone V SoC Development

Kit, the software notifies you of a successful kernel execution.
