Built-In Self Test

6.0Built-In Self Test

The CMM provides for a Built-In Self Test (BIST). The test will be run automatically after power-up or front-panel reset. This test will detect flash corruption as well as other critical hardware failures.

Results for the BIST are displayed on the console through the serial port during boot time. Results of BIST will also be available through the CLI if the OS successfully boots.

If the BIST detects a fatal error, the CMM will not be allowed to function as an active CMM.

6.1BIST 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 will alert users to any errors that occurred during boot.
