Description: The boot flash rev number.
What is cardFlashRev?
This reports the revision of the boot flash firmware, which is distinct from the card's main software revision and its EPROM revision. Because the boot flash is what actually loads the main firmware image at startup, a boot flash revision that's too old to support a newer main software image is a specific, checkable reason an upgrade attempt might fail to boot, separate from an EPROM compatibility issue. For example, a firmware upgrade fails to boot until the admin discovers cardFlashRev needs updating first to support the newer main software image's boot requirements.
Examples
