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
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.
Example output:
