N3000 Sample Test: Native Loopback fail

I try to run Sample Test: Native Loopback by using 'sudo ./hello_fpga', but it gives error Using OPAE C library version '1.3.7' build '81afe79' Error no matching accelerator: not found '...

Hi,

I might need the below info (PrintScreen will help)

rpm -qa | grep opae
check the OPAE version, also to confirm the step is correct.

The hello_fpga sample host application uses the OPAE library to test the hardware in native loopback mode (NLB).

I would suggest referring back to session 7.2.1 at link below (for detailed setup)

https://www.intel.com/content/www/us/en/programmable/documentation/iyu1522005567196.html
Follow the provided step, please let me know if you facing any problem.

What you have to do is the following

cd sw_sample
gcc -o hello_fpga -std=gnu99 -rdynamic -ljson-c -luuid -lpthread -lopae-c -lm -Wl,-rpath -lopae-c hello_fpga.c
sudo sh -c "echo 20 > /sys/kernel/mm/hugepages/hugepages-2048kB/nr_hugepages"
sudo ./hello_fpga

[guest@hw-rae-a3-l sw_sample]$ sudo ./hello_fpga

Using OPAE C library version '1.3.3' build 'c6c0d9f'

Thanks for the reply.

When following the tutorial, I don't know what is this variable '$OPAE_PLATFORM_ROOT'. After installation, I only have two folders. Here is the folder structures. (I only show 2 levels)

I am using 'N3000-2', the link you send me is for 'Intel Arria 10 GX FPGA', not for 'N3000-2', is that correct?

Here is the output

rpm -qa | grep opae

Hi Max,

How about the test result of "fpgainfo fme" and "fpgabist" ?

Apologize for wrong doc, can you please try out doc below

Intel® Acceleration Stack User Guide, Intel FPGA Programmable Acceleration Card N3000
Page 32/92, Session 6 Native : Loopback
https://www.intel.com/content/dam/www/programmable/us/en/pdfs/literature/ug/ug-ias-n3000.pdf
Please follow the step from extract the package to sudo ./hello_fpga

Just want to ensure that the step is correct, please let me know if you are still unable to get it.

Regards,

I think there is the correct doc for N3000-2?

https://www.intel.com/content/www/us/en/programmable/documentation/zsf1588015530773.html

I follow the instruction on this doc and I also follow the instructions on the doc you suggest, but none of them work.

Here is the error and the output for "fpgainfo fme" and "fpgabist".

Hi Max,

Thanks for double confirm that. We can confirm that there is no missing step/driver error.
May I know server OS and kernel version that you are using ? Currently PAC N3000 cards support:

CentOS Linux version 7.6 kernel 3.10 or kernel 4.19

Red Hat* Enterprise Linux* (RHEL) version 7.6 kernel 3.10

It is possible to happen if your OS is not in the suggested version or missing file (kernel headers)

Apart of that, is there any hardware you are running on ?

IF you don’t have an FPGA platform in your system.

It is expected for the software not to find any accelerators (well, to be fair, there aren't any ).

If you want to run your OPAE application without hardware, you can run it against a simulation of your accelerator in the AFU Simulation Environment (ASE).

You'll need to link your application against a different implementation of the OPAE library (libopae-c-ase instead of libopae-c) and run your accelerator RTL through a logic simulator.

Have a look at the AFU user guide for more details on how to use ASE.

In some case, the error might also occur if the FPGA image doesn’t match the test to do, hence the software can’t connect with the AFU which has the same accelerator ID

Hope this can help you
