mstflint – Firmware Burning Tool
The mstflint (Flash interface) utility performs the following functions:
Burns a binary firmware image to the Flash device attached to an adapter or a switch
device.
Burns an Expansion ROM image to the Flash device attached to adapters.
Queries for firmware attributes (version, GUIDs, UIDs, MACs, PSID, etc.)
Enables executing various operations on the Flash memory from the command line (for
debug/production).
Disables/enables the access to the device’s hardware registers, and changes the key
used for enabling. This feature is functional only if the burnt firmware supports it.
