Management Processor Monitor: Basic Operation
10009109-01 ATCA-9305 User’s Manual 9-3

BASIC OPERATION

The monitor performs various configuration tasks upon power-up or reset. This section
describes the monitor operation during initialization of the ATCA-9305 board. The flow-
chart (see Fig.9-2) illustrates the power-up and global reset sequence (bold text indicates
environment variables).

Power-up/Reset Sequence

The ATCA-9305 monitor follows the boot sequence in Fig.9-2 before auto-booting the oper-
ating system or application software. At power-up or board reset, the monitor performs
hardware initialization, diagnostic routines, autoboot procedures, free memory initializa-
tion, and if necessary, invokes the command line. See Fig.3-4 for the Cavium CN5860 pro-
cessor boot sequence. See Table 9 -6 for default environment variables settings.
