burningcommand. Moreover, the burn process cannot be failsafe when burning a blank Flash,
thereforethe -nofs flag must be specified.

Burning theMFA2 Images
Burning the MFA2 images enables the user to extract (i.e. unzip) 4MB images from MFA2 archive that
matches the device type and device PSID.If there are more than one matching images, the user may
use the--latest_fwflag and burn the latest firmware, or choose the required image from the user
menu.
Burning theMFA2 Images when the Device Includes a Valid Image
In this scenario, the user may (optional) provide a “—psid” flag and extract from the MFA2
archive the image that matches this flag, and this way actually change the PSID on the
device.
Burning theMFA2 Images when in Live Fish Mode
In this scenario, the user must provide a“—psid”flag and extract from the MFA2 archive the
image that matches this flag, and this way actually change the PSID on the device.
Cable Firmware Update (In-Field-Firmware-Update)
The In-Field-Firmware-Update (IFFU) tool works via the HCAs in the datacenters and is intended for
remote control. The tool is used to update cables transceivers' firmware.
Optical Cables and Transceivers are active network components which run firmware, and as any
component running firmware, the ability to update firmware is mandatory. Transceiver firmware
update is a system flow which requires the following elements:
Tool/Manager which will perform the firmware update
HCA firmware management used as a middleman between the Manager and the cable
transceiver
Transceiver firmware: target for upgrade
The figure below shows the tool/manager which runs on a remotely controlled HCA on host shown as
‘Device’.
The manager can query the transceivers type and the current running firmware to understand if an
update is required.When an update is required, the manager can apply set of commands that will
send the remote host device a new firmware images for the specific transceiver(s) and activate a
firmware update flow.The set of commands is defined with low level primitives to support full
The device flash MUST have all relevant device information (signatures, PSID, VPD,
DEV_INFO, MFG_INFO, etc.) valid since MFA2 format does not have that information and
without the burn process will fail.
#mstflint -d <device> -i <mfa2 file> --psid <PSID string> (optionally) --
latest_fw (optionally) –silent (optionally) b (or burn)

Burning mfa2 requires installing mstflint with --enable-fw-mgr option.

This capability is supported only hosts with NVIDIA ConnectX-6 adapter cards.
