FPGA classification_sample freezes

[VDemc2]

Hello,

we have Mustang F100-A10 and TANK-870 AIoT Dev. Kit.

We have followed the official guide for the latest openvino to setup the 2019R1  openvino and our FPGA card.

We were able to run "aocl diagnose" and we see there is the card as you can see below.

ieisw@ieisw-SER0:~$ aocl diagnose
--------------------------------------------------------------------
Device Name:
acl0

BSP Install Location:
/opt/altera/aocl-pro-rte/aclrte-linux64/board/a10_1150_sg1

Vendor: Intel(R) Corporation

Phys Dev Name  Status   Information

acla10_1150_sg10Passed   Intel Vision Accelerator Design with Intel Arria 10 FPGA (acla10_1150_sg10)
                       PCIe dev_id = 2494, bus:slot.func = 01:00.00, Gen3 x8
                       FPGA temperature = 61.6406 degrees C.

DIAGNOSTIC_PASSED
--------------------------------------------------------------------

The 

./demo_squeezenet_download_convert_run.sh -d HETERO:FPGA,CPU

succeeded as well as demo_security_barrier_camera.sh with device HETERO:FPGA,CPU

However when we try to run classification_sample demo as below, it sometimes stuck forever. Not after certain amount of inference calls but randomly. Sometimes it finished with -ni set to 3000 but sometimes it stuck when we set -ni to 10. Below is the command we used.

/<path>/inference_engine_samples_build/intel64/Release/classification_sample -i /opt/intel/openvino/deployment_tools/demo/car.png -m /<path>/squeezenet1.1_FP16/squeezenet1.1.xml -d HETERO:FPGA,CPU -ni 10

While this execution is running we are not able to call "aocl diagnose" at all.

We are really out of ideas and we are starting to suspect that the FPGA card is broken. So any help or suggestion is highly appreciated.

PS: We have skipped the part in documentation which is about USB Blaster (we dont have this thing).

I think that you may be correct and should contact fpga support. You can find more information for it here  https://www.intel.com/content/www/us/en/programmable/about/contact/technical-support.html ;

Thanks, do you happen to know if USB Blaster is required for "aocl program"? Because we were able to program a bitstream with success message.
