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

'lspci | grep acc' gives

08:00.0 Processing accelerators: Intel Corporation Device 0b30

I also try to use 'sudo ./hello_fpga -B 0x08' but it gives the same error.

Any idea on how to solve this? Thanks!

    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)

    What you have to do is the following

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

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

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

    Running Test

    Let me know if this helps.

      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

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

        Regards,
