Hi.

Compiling RTL opencl example1,

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

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

Querying device for info:

    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.html 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.html

    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_started.pdf

    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
