CAVIUM MONITOR
The primary function of the monitor software is to transfer control of the hardware to the
user’s application. Secondary responsibilities include:
• low-level initialization of the hardware
•diagnostic tests
• low-level monitor commands/functions to aid in debug
Start-up Display
At power-up or after a reset, the Cavium monitor runs diagnostics and reports the results in
the start-up display, see an example in
Fig. 3-3. During the power-up sequence, the monitor
configures the board according to the environment variables (see “MPC8548 Environment
Variables” on page 9-26). If the configuration indicates that autoboot is enabled, the moni-
tor attempts to load the application from the specified device. If the monitor is not config-
ured for autoboot or a failure occurs during power-up, the monitor enters normal
command-line mode. The monitor command prompt in
Fig.3-3 is the result of a successful
hardware boot of the ATCA-9305.

Note: There will be either a 1 or 2 in front of the monitor prompt indicating which Cavium processor is prompting.
Power-up/Reset Sequence
The Cavium CN5860 processor follows the boot sequence in Fig.3-4 before auto-booting
the operating system or application software. At power-up or board reset, the monitor per-
forms hardware initialization, diagnostic routines, autoboot procedures, and if necessary,
invokes the command line. See
Ta bl e 3- 5 for default Cavium environment variables settings.
