Note

It is recommended to upgrade your BlueField product to the latest software and firmware versions available to benefit from new features and latest bug fixes.

  1. Provide the image from BFB file. Run:

    Copy
    Copied!
                

    # mlx-mkbfb -x <BFB>

    For example:

    Copy
    Copied!
                

    # mlx-mkbfb -x DOCA_v1.1_BlueField_OS_Ubuntu_20.04-5.4.0-1017.17.gf565efa-bluefield-5.4-2.4.1.3-3.7.1.11866-1-aarch64.bfb

    Warning

    mlx-mkbfb is a Python script that can be found in BlueField release tarball under the /bin directory or in the Bluefield Arm file system /usr/bin/mlx-mkbfb.

  2. Copy the 2 dumped files, dump-image-v0 and dump-initramfs-v0 into the PXE server tftp path.

  3. In the PXE server create a boot entry. For example:

    Copy
    Copied!
                

    /var/lib/tftpboot/grub.cfg   set default=0 set timeout=5 menuentry 'Bluefield_Ubuntu_20_04_From_BFB' --class red --class gnu-linux --class gnu --class os { linux (tftp)/ubuntu2/dump-image-v0 ro ip=dhcp console=hvc0 console=ttyAMA0 initrd (tftp)/ubuntu2/dump-initramfs-v0 }

  4. Define DHCP.

    Copy
    Copied!
                

    /etc/dhcp/dhcpd.conf   allow booting; allow bootp;   subnet 192.168.100.0 netmask 255.255.255.0 { range 192.168.100.10 192.168.100.20; option broadcast-address 192.168.100.255; option routers 192.168.100.1; option domain-name-servers <ip-address-list> option domain-search <domain-name-list>; next-server 192.168.100.1; filename "/BOOTAA64.EFI"; }   # Specify the IP address for this client. host tmfifo_pxe_client { hardware ethernet 00:1a:ca:ff:ff:01; fixed-address 192.168.100.2; } subnet 20.7.0.0 netmask 255.255.0.0 { range 20.7.8.10 20.7.254.254; next-server 20.7.6.6; filename "/BOOTAA64.EFI"; }
