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.
    https://www.intel.com/content/www/us/en/programmable/documentation/rjg1562957780901.html
  • 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

I have followed the instructions to install kernel headers. Here is my os/kernel version.

$ cat /etc/os-release
NAME="CentOS Linux"
VERSION="7 (Core)"
ID="centos"
ID_LIKE="rhel fedora"
VERSION_ID="7"
PRETTY_NAME="CentOS Linux 7 (Core)"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:centos:centos:7"
HOME_URL="https://www.centos.org/"
BUG_REPORT_URL="https://bugs.centos.org/"

CENTOS_MANTISBT_PROJECT="CentOS-7"
CENTOS_MANTISBT_PROJECT_VERSION="7"
REDHAT_SUPPORT_PRODUCT="centos"
REDHAT_SUPPORT_PRODUCT_VERSION="7"


$ cat /etc/centos-release
CentOS Linux release 7.6.1810 (Core)


$ uname -r
4.19.106-rt45

And I have an N3000-2 inserted to the server. You can find the output of 'lspci | grep acc' in my original question post.

There is some error in the output of 'fpgabist -i 0x0b30'. I don't know if that indicate anything wrong. Could you please help me check that?

Also, I have another post and I think that problem might be related to this one. Could you please take a look? Thanks!

    Hi Max,

    Thanks for your reply, as mention, It is expected for the software not to find any accelerators
    if you don’t have an FPGA platform in your system.
    Maybe you can try run it against a simulation of your accelerator in the AFU Simulation Environment (ASE).

    Meanwhile for the case related to "./nvmupdate64e and device not found"
    I am working on it, might need sometime expected will reply you within 3 days.

    Regards,

      Hi Max,

      I think I had answered your question about "why the accelerator not found".
      I will set this as close-pending.
      Let me know if you still have any other questions about this issue.
      Else, I will close this after 3 days.

      Regards,
