Getting Started with the Intel FPGA SDK for OpenCL Pro Edition for Linux

SDabh · ‎05-16-2019

Hello All,

I am working on Arria 10sx board and I want to run hello world example for OpenCL.

I have followed the steps "getting started eith the intel FPGA SDK for OpenCL Pro Edition for Linux" from "https://www.intel.com/content/www/us/en/programmable/documentation/mwh1391807309901.html#ewa1435159392013" this document.

1. Set up the Env. variables:

a. PATH and LD_LIBRARY_PATH

2. result for aocl version:

3.Installing FPGA board:

After follwoing commands for installing FPGA board, I tried following command "aocl diagnose" an result i am getting is:

I am not sure where I am going wrong can anyone help me with this issue?

The log is quite clear as to what the problem is, and is even saying what should be done:

Unable to find the kernel mode driver.
 
Please make sure you have properly installed the driver. To install the driver, run
 
aocl install

Did you run "aocl install" as part of the steps mentioned in the Getting Started Guide?

SDabh · ‎05-17-2019

@HRZ Yes, I have tried "aocl install" and it is not running successfully hence I have ran the "aocl diagnose" command and pasted its result here. It does say, no device connected but I do have board connected and bsp files under hld/board/a10soc.

Error message is as follows:

aocl install: Setting up the FPGA Client Driver (FCD) to the system.

Install the FCD file to /opt/Intel/OpenCL/Boards

Installing the board package driver to the system.

--------------------------------------------------------------------

Warning: No board installation routine supplied.

Please consult your board manufacturer's documentation or support

team for information on how to properly install your board.

--------------------------------------------------------------------

Could you just give me brief idea if there is something which is missing in documents or I am not doing correctly?

Thank you

HRZ · ‎05-20-2019

I just realized you are using an SoC board and the a10soc BSP does not provide an install routine (which makes perfect sense since it is not supposed to be installed on an x86 machine). I have never used this board but the Cyclone V SoC board I used a long time ago came with a custom Linux that you wrote onto an SD Card and when you loaded from that OS, there was some OpenCL initialization script that set up the OpenCL environment. I am not sure how/why the diagnose script is seeing NVIDIA and Intel platforms in your case; are you running these commands on an x86 host?

SDabh · ‎05-21-2019

Hello HRZ, thank you for reply. So the first thing first, I have the arria 10 soc board for which the image which I got with the board is broken. So what I am trying here is, considering version 17. has a enough stablility and trying to use 17 image. But for this image I don't see any init_opencl file. So, workaround I downloaded RTE 17.0 version from intel which has init_opencl script but this only has support for a10_ref(GX ) board. So next thing I did is just copied the hld/board/a10soc folder to sd card and then I tried to do aocl diagnose and I am still getting the same result.

Hi,

Are you running on Windows 8 or 10? If you the "aocl diagnose" fail even if your board is installed, this is a known issue and here is the work around:

On Windows 8.1 or Windows 10 systems, you might also need to disable signed driver verification. For details, see the following articles:

See if it helps.

Regards.

Hi eli.ign, I am not using windows. I am using linux.

EBERLAZARE_I_Intel · ‎05-22-2019

Hi,

Following mention by HRZ, for SoC board the "aocl install" is not required because I believe everything is pre-installed on the supplied flash card image.

And the "aocl diagnose" should be executable.

Can you run "aocl list-devices" what is the output?:

*The list-devices utility lists all the devices installed in a host machine, grouped by board packages.

The list-devices utility is similar to the diagnose utility. It first verifies the installation of the kernel driver and then lists all the devices.

Regards.

SDabh · ‎05-22-2019

Hi,

Yes but the sd card image which I have got with my soc board is broken and so I am manually trying to install image and necessary tools.

EBERLAZARE_I_Intel · ‎05-23-2019

Hi,

May I know where did you get the image? I assuming the image is not supported, since the aocl diagnose causing error.

You can get the SD card image from rocketboards.org, for 19.1:

https://rocketboards.org/foswiki/Documentation/GSRD191ReleaseNotes

Hope this help.

SDabh · ‎05-23-2019

Hi,

Yes, I am using the same image but somehow it doesn't come with OpenCL RTE. So finally for now I am using 18.1 version and it is working for me.

Thank you for your help! I am still looking for 19.1(latest) image, but for now I am okay with 18.1.

CJohn56 · ‎10-03-2019

Hi,

I am having the same problem with the same board and Intel OpenCL for FPGA version 19.3.

I have tried to follow the guide on building the SD card, but I am having trouble with building the driver, due to generating the device tree blob.

Will there be released a pre built SD card image for version 19.3 (or 19.1), or is 18.1 the latest version as SDabh mentions, which comes with a pre built image?

I have tried the 19.1 GSRD, but it does not come with the driver.
