NDK firmware support

  • Ethernet cores that are supported in the NDK firmware:
  • PCIe cores that are supported in the NDK firmware:

    • R-Tile in the PCIe Module

    • See the <NDK-FPGA_root_directory>/card/silicom/fb2cdg1/config/card_conf.tcl file for supported PCIe configurations.

  • Makefile targets for building the NDK firmware (valid for Minimal app, may vary for other apps):

    • Use make 400g2 command for firmware with 2x400GE (default).

  • Support for booting the NDK firmware using the nfb-boot tool:

    • YES, starting with the nfb-framework version 6.28.5

Note

To build the NDK firmware for this card, you must have the Intel Quartus Prime Pro and PACSign tool installed, including a valid license.

Board Variants

This card exists in multiple variants. The correct variant for the firmware build can be selected using the Makefile parameter BOARD_VARIANT, for example as follows:

$ cd <NDK-FPGA_root_directory>/apps/minimal/build/fb2cdg1
$ make BOARD_VARIANT=1

Allowed values of BOARD_VARIANT parameter

  • BOARD_VARIANT=1 - The board uses FPGA part number AGMF039R47A1E2VC (Production sample).

  • BOARD_VARIANT=0 - The board uses FPGA part number AGMF039R47A2E2VR0 (Engineering sample).

Initial Boot instructions

The card itself should be preloaded with firmware designed by Silicom. This design can be used to load an FPGA image to the BMC flash via PCIe using the Silicom rawcardtool tool.

Execute the following steps to perform the manual initialization:

  1. Obtain PCIe address of the card by the command below. In this example, the PCIe address is 01:00.0 and will be used in the next steps:

    $ lspci | grep "Silicom Denmark Device"
01:00.0 Ethernet controller: Silicom Denmark Device 0001

  2. Ensure the card respond to memory space accesses by command:

    $ setpci -s 01:00.0 COMMAND=0x0002

  3. Flash the fpga_page1_pacsign_user1.bin file to the card using RawCardTool provided by Silicom:

    $ rawcardtool_fjord --device 01:00.0 --flash fpga_page1_pacsign_user1.bin

  4. Set your design as default by command:

    $ rawcardtool_fjord --device 01:00.0 --fpgadefault user1

  5. Boot your design executing:

    $ rawcardtool_fjord --device 01:00.0 --reboot-fpga user1

Note

The fpga_page1_pacsign_user1.bin file will be located in the build folder of your application after building. For NDK-FPGA, the folder is ndk-fpga/apps/minimal/build/fb2cdg1.

Note

If some bars are unmapped, power cycle the server.

If the rawcardtool tool is unavailable, it is possible to use JTAG to load the design (SOF file), and nfb-boot command to load the BMC flash with the FPGA image:

$ nfb-boot -f0 fb2cdg1-minimal-pcie1xgen5x8x8-400g2.nfw
