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.
Provide the image from BFB file. Run:
# mlx-mkbfb -x <BFB>
For example:
# 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
Warningmlx-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.
Copy the 2 dumped files, dump-image-v0 and dump-initramfs-v0 into the PXE server tftp path.
In the PXE server create a boot entry. For example:
/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 }
If additional parameters must be set, use the bf.cfg configuration file, then add the bfks parameter to the Linux command line in the grub.cfg above.
menuentry 'Ubuntu22.04 From BFB with bf.cfg' --class red --class gnu-linux --class gnu --class os { linux (tftp)/dump-image-v0-ubuntu22 console=hvc0 console=ttyAMA0 bfnet=oob_net0:dhcp bfks=http://15.22.82.40/bfks initrd (tftp)/dump-initramfs-v0-ubuntu22 }
Where bfks is a BASH script that creates a /etc/bf.cfg file. For example:
cat >> /etc/bf.cfg << 'EOF' DEBUG=yes ubuntu_PASSWORD='$1$3B0RIrfX$TlHry93NFUJzg3Nya00rE1' EOF
Define DHCP.
/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"; }
Connect to the BlueField console via UART or RShim console.
Reboot Arm.
Interrupt the boot process into UEFI menu.
