aocl list-devices : No devices attached for package:

Please post the environmental variables you have set that are related to the Intel tools. There is likely something wrong with the way you have set the "ALTERAOCLSDKROOT" variable.

I am having the same problem - and I can provide more details. Perhaps answering my issue will help us both... I have the exact same issue: OpenCL doesn't know about my PAC card.

PLEASE help educate us about how to debug/solve this...

(I have ENVIRONMENT variables in NEXT post)...

My QUESTION: How do I debug (and solve) a “ERROR: CL_DEVICE_NOT_FOUND” for a system with a PAC card installed?

I think my issue is this: OpenCL can’t find the PAC card.

Here is an example of trying to use it:

% ~/inference_engine_samples/intel64/Release/security_barrier_camera_sample -d CPU -d_va FPGA -d_lpr CPU -i /opt/intel/computer_vision_sdk_fpga_2018.3.343/deployment_tools/demo/../demo/car_1.bmp -m /opt/intel/computer_vision_sdk_fpga_2018.3.343/deployment_tools/demo/../intel_models/vehicle-license-plate-detection-barrier-0106/FP32/vehicle-license-plate-detection-barrier-0106.xml -m_va /opt/intel/computer_vision_sdk_fpga_2018.3.343/deployment_tools/demo/../intel_models/vehicle-attributes-recognition-barrier-0039/FP32/vehicle-attributes-recognition-barrier-0039.xml -m_lpr /opt/intel/computer_vision_sdk_fpga_2018.3.343/deployment_tools/demo/../intel_models/license-plate-recognition-barrier-0001/FP32/license-plate-recognition-barrier-0001.xml

Query for number of devices failed

Here is evidence that the card is plugged in (with BOARD info and everything!)…

% bwconfig --list

There are no mapped devices in your system.

I did this after trying the run, and then tried the run again… NO change, OpenCL still doesn’t see the card… see this:

% aocl diagnose

--------------------------------------------------------------------

Warning:

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

I’m wondering - is “a10_ref” appropriate for a PAC (Arria 10)? I have NO other board reference files to point to - but the name does concern me. If there are OpenCL files for the PAC card to try… I’m eager to know that.

I would REALLY enjoy any feedback/hints/tips on how to debug (and solve) a “ERROR: CL_DEVICE_NOT_FOUND” for a system with a PAC card installed… THANK YOU!!!

@JRein, I don't think the PAC card is the same as the a10_ref board. The latter is a development board with one bank of DDR3 and one bank of DDR4 while the PAC card has two DDR4 banks. You most definitely need a BSP specific to the PAC card. Contact whoever you purchased the board from to get the respective BSP. Furthermore, it seems you have not even set up your board. You need to program the board via JTAG with a base firmware to enable the PCI-E core before it is detected using aocl diagnose. Intel's documents outline the steps to do so.

Thank you. Yes, it turns out "PAC A10" is different than "A10 REF" - and I needed "PAC A10." And, the firmware was flashed but with a version that was too old now for the current OpenCL. So, I needed to flash a newer firmware in the PAC card. Once I got the PAC A10 BSP, and flashed the newer firmware (that matches the BSP) - everything worked. A very helpful support engineer at Intel helped me find the right files and everything works now. The key was having the right combination of firmware on the card, OpenCL driver and BSP, and other libraries... and then it all just work. Very nicely indeed.
