Hi,

May I know if you follow the guide in https://docs.openvinotoolkit.org/latest/_tools_downloader_README.html to install all the prerequisite dependencies file?

[Titanameda]

Thank you for your reply

No , I have not ,

so now I have installed the necessary requirements , as below

1./opt/intel/openvino/deployment_tools/open_model_zoo/tools/downloader# python3 -mpip install --user -r ./requirements.in

but the error persists ,i have followed this guide

https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux_fpga.html

2. Isn't there another approach to program the Mustang? apart from USB blaster , via PCIe something like opencl?

3. any guides on how to connect the to the host machine ,like power, the harware connections ?

[JohnT_Intel]

Hi,

The error looks like you are not able to download the model from Github. Could you check your internet connection?

Currently you have not move towards running it on FPGA yet as it is more towards the package downloading and setup.

[Titanameda]

hello ,

so I am referring this document and in page 20 , a driver has to be installed , that particular driver is not present , so where can i find the driver , from intel? or any other alternative method.

Thank you

[JohnT_Intel]

Hi,

For the PCIe driver then please refer to https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R3.html which you will need to download the fpga_support_files.tgz which contain the BSP and driver. Please follow the step provide to install the card.

The next step involves flashing with the USB flasher ,

2.What about Opencl methodology of sending .aocx files to fpga, or any other methodologies.

Thank You

[JohnT_Intel]

Question No:1:

1. https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2019R1.html , following this guide, so after step 10 , I get the following errors:

The error that you observed is not related to FPGA. So you should be able move forward with your testing. 

Question No 2:

The next step involves flashing with the USB flasher ,

1.Cant we achieve this without the USB flashing ?

You only need to do it the 1st time if you are it is preloaded with the image with the same OpenVINO version.

2.What about Opencl methodology of sending .aocx files to fpga, or any other methodologies.

If you are just want to run different topology then you can use "aocl program ***.aocx" which will update the FPGA topology. If the preloaded image is using different OpenVINO version then you will need to use USB Blaster to flash it before you are able to program it.

Hi,

https://files.icp-deutschland.de/produkte/KC001777/web/Mustang-F100-A10_UMN_v1.02-manual-20190212.pdf,

pg:20 and 21

In this guide , the flashing is not done , an alternate method is provided , does this work?

[JohnT_Intel]

Hi,

Yes. it will work if you are able to program it. If you see issue on programming it then you will need to flash the FPGA.

How to resolve this

[Titanameda]

The guide which is followed :

https://docs.openvinotoolkit.org/latest/_docs_install_guides_VisionAcceleratorFPGA_Configure_2018R5.html

[JohnT_Intel]

Hi,

Its look like you are installing the wrong BSP. You will need to run "export AOCL_BOARD_PACKAGE_ROOT=/opt/altera/aocl-pro-rte/aclrte-linux64/board/a10_1150_sg1" as this will be the BSP installed into your system as you are using this board.

If you "a10_1150_sg1" is install in the different directory then you can changed "export AOCL_BOARD_PACKAGE_ROOT=/opt/intelFPGA_pro/18.1/hld/board/a10_1150_sg1" which is the same directory of the a10_ref BSP.

[Titanameda]

Hi

Hi,

Could you performed "AOCL UNINSTALL" in order to uninstall the BSP that is not used? Are you able to detect the board when you use "lspci" command?
