ConnectX-4 onwards Adapter Cards Family

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.

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

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 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.

   Copy

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

4. Set device GUIDs and MACs.

   Copy

   Copied!

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

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

   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.
