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.

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.

Burning the ConnectX®-4 onwards Adapter Cards Family

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

In order to burn a new device, follow the steps below:

  1. Disable the Write protection.

    # flint -d /dev/mst/mt521_pciconf0 -ocr hw set Flash0.WriteProtected=Disabled

  2. Burn the entire flash.

    # 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

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

  4. Enable flash quad SPI IO operations.

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

Method 2: Generating Firmware Image with Blank GUIDs, Burning and Setting GUIDs on the Device

In order to burn a new device, follow the steps below:

  1. Disable the Write protection.

    # flint -d /dev/mst/mt521_pciconf0 -ocr hw set Flash0.WriteProtected=Disabled

  2. Burn the entire flash.

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

  3. Set device manufacture GUIDs and MACs.

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

  4. Set device GUIDs and MACs.

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

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

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

    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.

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


    1. To view flash settings:

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

    2. To view assigned GUIDs:

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

    3. To change a GUID after the initial burn:

      # flint -d /dev/mst/mt4115_pciconf0 -ocr -guid 0xe41d2d0300570fc0 sg

    4. To change a MAC after the initial burn:

      # flint -d /dev/mst/mt4115_pciconf0 -ocr -mac 0x0000e41d2d570fc0 sg

    5. To change a GUID and derive MAC from it after the initial burn, run:

      # flint -d /dev/mst/mt4115_pciconf0 -ocr -uid 0xe41d2d0300570fc0 sg
