Hi.

Compiling RTL opencl example1,

1.compiling host code (via make file) is completed

2. while Running (host executable :host ) get the following error

What is the reason that device is not found?

 

Thank you!

Have you set up your board correctly? Does "aocl diagnose" pass? That error happens when the runtime cannot detect your board.

I am just emulating , I believe that aocl diagnose is to test if the board is connected

Then, are you passing "CL_CONTEXT_EMULATOR_DEVICE_ALTERA=1" (for v16.1.2 and below) or "CL_CONTEXT_EMULATOR_DEVICE_INTELFPGA=1" (for v17.0.0 and above) when running the binary compile for emulation?

Which version of the compiler are you using? Have you followed the instructions of Section 8 in the Programming Guide?

Hi,

From the message: CL_DEVICE_NAME              = 

CL_DEVICE_VENDOR             = 

CL_DEVICE_VENDOR_ID           = 0

CL_DRIVER_VERSION            = 

 

It seems like the driver and device is not setup correctly.

 

You may need to follow the user guide as below to install driver and device:

   2. Install the driver from the selected board package.

   3. Properly install the device in the host machine.

   4. Configure the device with a supported OpenCL design.

Call "aocl diagnose <device-names>" to run diagnose for specified devices

Call "aocl diagnose all" to run diagnose for all devices

 

 

The same error, device not found exists .

In the above aocl diagnose it is referring to some other BSP (libaltera_a10_1150_sg1_mmd.so) to find where should i edit it

These are the variables :

 

INTELFPGAOCLSDKROOT is set to /opt/intelFPGA_pro/18.1/hld. Using that.

 

Will use $QUARTUS_ROOTDIR_OVERRIDE= /opt/intelFPGA_pro/18.1/quartus to find Quartus

 

AOCL_BOARD_PACKAGE_ROOT is set to /opt/intelFPGA_pro/18.1/hld/board/a10_ref. Using that.

Adding /opt/intelFPGA_pro/18.1/hld/bin to PATH

Adding /opt/intelFPGA_pro/18.1/hld/host/linux64/lib to LD_LIBRARY_PATH

Adding /opt/intelFPGA_pro/18.1/hld/board/a10_ref/linux64/lib to LD_LIBRARY_PATH

These are my variables in bash

 

####intel openvino###

export INTELFPGAOCLSDKROOT="/opt/intelFPGA_pro/18.1/hld"

 

export QSYS_ROOTDIR="/home/tata/intelFPGA_pro/18.1/qsys/bin"

export PATH=/home/tata/intelFPGA_pro/18.1/quartus/bin:$PATH

source /opt/intel/openvino/bin/setupvars.sh

export PATH=/opt/intelFPGA_pro/18.1/quartus/bin:$PATH

#opencl via openvino

export PATH=/opt/intelFPGA_pro/18.1/hld/bin:$PATH

source $INTELFPGAOCLSDKROOT/init_opencl.sh

 

 

i am using openvino BSPs as well!

so I believe , the paths are getting mixed

 

 

Thank You

Hi,

 

From your comment above with the path provided, I saw that you are using the OpenVino toolkit. Just a confirmation, do you using OpenVino toolkit?

May I know what device you are using? This is because the Openvino software have different installation guide from OpenCl SDK software.

 

Thanks

Hi,

Yes I am using openvino toolkit , I neeed to install both BSP (MUSTANG F100 and A10) and reference a10_ref

Hi,

Can you try to install OpenVino for MUSTANG-F100-A10 by follow the link below:

https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R3....

 

Do you have two board which is MUSTANG F100-A10 and Arria 10GX FPGA board as you had mentioned you want to install both BSP? Since these two board use different BSP and compiler software.

 

Thanks

I have installed both BSP's , I have MUSTANG board connected to host via PCIe ,I need to emulate for both devices

This is what i get , but still when i run the host exe ,device is not found

cl_device not found

Hi,

Both the mustang and a10_ref BSPs are installed ,I have mustang board alone , but I need to emulate on both boards.

1.PNG

so this is what is get.

The device is still not found

Hi,

 

From the path provided as comment above, it seem like the path is not correct as compare with https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R3.... in step 11. 

 

I would like to suggest to do a clear uninstall for the BSP of both device and OpenVINO toolkit. 

 

Then do a install of OpenVINO toolkit for Mustang-F100-A10 based on the link below: 

https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R3....

 

After you have successful run and compile sample application for Mustang-F100-A10 device, then only installed another a10_ref BSP in the same path: /opt/altera/aocl-pro-rte/aclrte-linux64/board

 

Thanks

ok, As of now i need to emulate alone , so my understanding is I do not need the board, but for mustang it seems u need it . (even for BSP installation ), (I do not have the appropriate USB Blaster as of now )

so , now i would like to emulate for a_10_ref , for this what is the procedure ? the steps, can i use the opencl installation that are installed along with openvino or should i download a separate Opencl RTE

Hi,

I am sorry for misunderstanding the information about OpenVINO toolkit. I had check internally about the information about OpenVINO toolkit.

 

Firstly, the OpenVINO toolkit cannot run emulation. To run emulation, you have to download and follow the instruction as the link below: https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/hb/opencl-sdk/aocl_getting_...

 

Secondly, the BSP for Mustang-F100-A10 is a part of installation package in OpenVINO toolkit. Hence you can take the Mustang-F100-A10 BSP from OpenVINO toolkit and place it into the OpenCL SDK software installation path ie: <installation_path_opencl>\board to used it as BSP.

 

Please note that to set all the environment variable in correct path.

 

Also, you can look into the link below to know the OS supported for each software version:

https://fpgasoftware.intel.com/requirements/19.3/

 

Please note that the software in Pro Edition and Standard Edition is required paid license.

 

Thanks
