I am having the same issue in OpenVINO 2019R1. classification_sample but classification_sample -d HETERO:FPGA,CPU does not.

[jjunn]

And I install dev not rte,the right one. so I don't have /opt/altera/aocl-pro-rte/aclrte-linux64

Hi,

May I know which aocx file do program into the board? could you try to program other aocx file to see if the classification_sample is working?

Have you try to follow the step use to install the board in https://docs.openvinotoolkit.org/latest/_docs_install_guides_installing_openvino_linux_fpga.html? Are you running in root?

[jjunn]

The aocx file that I used is 2019R1_RC_FP11_ResNet_SqueezeNet_VGG.aocx . I followed the step ,and I am running in root. The problem is the guide providing a runtime version. And I install the dev version in the right of the picture.

[JohnT_Intel]

Could you try other aocx file to see if you are facing the same issue?

[jjunn]

I am facing the same issue when I try other aocx file

[JohnT_Intel]

Could you try to performed diagnose on the board (aocl diagnose acl0)?

this is the error

this is my init_openvino.sh

[jjunn]

what should I do to solve this problem?

[jjunn]

I can run the hellworld sample,but there is still a problem when runing 2019R1_RC_FP11_ResNet_SqueezeNet_VGG.aocx

[JohnT_Intel]

Hi,

Have you try to run the diagnostic tools? Do you have another board to test it as I am suspect that the board might be damaged.

[jjunn]

It is a new board. And I have find the same problem link:https://software.intel.com/en-us/forums/computer-vision/topic/808441#comment-1940333

[jjunn]

And it is a runtime version ,and I use a dev version ,and it should be sloved

[JohnT_Intel]

Hi,

Could you check if you have "/opt/altera/aocl-pro-rte/aclrte-linux64" folder? The reason is that this is part of the OpenVINO installation. If you are able to find it then could you try to setup the environement for "INTELFPGAOCLSDKROOT " to this directory.

[jjunn]

Yes，I find it ，and the FPGA is running successfully.

But, I think it is the runtime problem. It did not solve the problem fundamentally.

because it notice me :

aoc was not found, but aocl was found. Assuming only RTE is installed.

And I have installed the DEV,not RTE .

[JohnT_Intel]

Hi,

RTE version is sufficient when you are just running the demo. Could you change the environment for "INTELFPGAOCLSDKROOT " to "/opt/altera/aocl-pro-rte/aclrte-linux64", This should be able to help you based on the other forum discussion.
