ConnectX-4 onwards Adapter Cards Family

NVIDIA Firmware Tools (MFT) Documentation v4.28

Upon first time device burning, the GUIDs, MACs and VPD of the device are required to be set on the flash.

The sections below demonstrate two methods of burning a new ConnectX-4 onwards device in order to set these initial settings. Subsequent firmware updates will not change these settings.

Note

flint for OEM is required for burning ConnectX-4 onwards adapter cards family for the first time.

For information regarding GUIDs, MACs and VPD, please refer to Accessing Remote InfiniBand Device by Direct Route MADs.

Method 1: Generating Firmware with Specific GUIDs and MACs and Burning it on the Device

    # flint -d /dev/mst/mt521_pciconf0 -i ./ fw-ConnectX4- MCX454_Ax.bin -ocr -ignore_dev_data - allow_psid_change -nofs --yes burn

  3. Set Write protection

    Copy
    Copied!
                

    # flint -d /dev/mst/mt521_pciconf0 -ocr hw set Flash0.WriteProtected=Top,8-SubSectors

  4. Enable flash quad SPI IO operations.

    Copy
    Copied!

  3. Set device manufacture GUIDs and MACs.

    Copy
    Copied!
                

    # flint -d /dev/mst/mt521_pciconf0 -ocr -guid 0xe41d2d0300570fc0 -mac 0x0000e41d2d570fc0 smg

  4. Set device GUIDs and MACs.

    Copied!
                

    # flint -d /dev/mst/mt521_pciconf0 -ocr -guid 0xe41d2d0300570fc0 -mac 0x0000e41d2d570fc0 sg

  5. Set Write protection on the last sector using flint:

    Copy
    Copied!
                

    # flint -d /dev/mst/mt521_pciconf0 -ocr hw set Flash0.WriteProtected=Top,8-SubSectors

    Note

    The command may vary based on the Flash type used.

    Protection_type can be :

    • 1- Top,8-SubSectors, if it is in [W25QxxBV]

    • 2- Top,1-Sectors, if it is in [MX25L16xxx, N25Q0XX, IS25LPxxx, S25FL256L, MX25Lxxx, W25Qxxx, MX25Uxxx]

  6. Enable flash quad SPI IO operations.

    Copy
    Copied!
                

    # flint -d /dev/mst/mt521_pciconf0 -ocr hw set QuadEn=1

    1. To view flash settings:

      Copy
      Copied!
                  

      # flint -d /dev/mst/mt521_pciconf0 -ocr hw query

    2. To view assigned GUIDs:

      Copy
      Copied!
                  

      # flint -d /dev/mst/mt521_pciconf0 -ocr

    3. To change a GUID after the initial burn:

      Copy
      Copied!
