RTM-ATCA-SXXX Overview

Each image contains a CRC signature which is validated by the system prior to loading. The normal methods for updating these code images is to establish a management connection, ( see chapter 3 ) login as administrator, and utilize either the command line interface (CLI) or web-based graphical user interface (GUI) interface outlined later in this chapter . Both of these mechanisms require that the existing firmware is known-good and intact.

Additionally, an alternate emergency recovery method is provided to repair flash contents that are blank, erased or corrupted.
