Built-In Self Test (Bist); Bist Test Flow - Intel NetStructure MPCMM0001 Software Instructions

Built-In Self Test (BIST)

The CMM provides for a Built-In Self Test (BIST). The test is run automatically after power up.
This test detects flash corruption as well as other critical hardware failures.
Results of the BIST are displayed on the console through the serial port during boot time. Results
of BIST are also available through the CLI if the OS successfully boots. If the BIST detects a fatal
error, the CMM is not allowed to function as an active CMM.

BIST Test Flow

The following state diagram shows the order of the tests RedBoot runs following a power-up or
front-panel reset. On every state before reaching active CMM, if there is an error, RedBoot will log
the error event into the EEPROM, route the error message to the serial port, and continue booting.
If the execution hangs before the OS loads due to the nature of the error, the CMM hangs. If the OS
successfully boots, it alerts users to any errors that occurred during boot.
