    The image is not provided with the acceleration stack. Can you check with your local FAE? Thanks.

Hi @SeanMa

b3:00.0 Processing accelerators: Intel Corporation Device 0b30
b7:00.0 Processing accelerators: Intel Corporation Device 0b32

==> This is expected. Cards are shipped with the default DID 0b30/0b32 as you saw.

But according to https://doc.dpdk.org/guides/bbdevs/fpga_5gnr_fec.html it should have something with deviceID 0d8f Is there anything we missed?

==> You will only see 0d8f if you have programmed the 5GNR FEC image into the card.

    Thanks for the answer, just wonder if there is any instruction for how to program FEC image into the card?

      If you have installed the Acceleration Stack, and if you have the image, run below:

      fpgasupdate <BIN filename> <BDF>

      When it completed update...run

      rsu bmcimg <BDF>

      Example:

      fpgasupdate example.bin 1a:00.0

      rsu bmcimg 1a:00.0

        Correction: you must install the Acceleration Stack in order to run those commands. It is not a "if", it is a MUST. You can either install the RTE or the Development version.
