Emerson ATCA-9305 Manuel D’Utilisation

 Basic Operation

ATCA-9305 User’s Manual

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 

) illustrates the power-up and global reset sequence (bold text indicates 

environment variables).

The ATCA-9305 monitor follows the boot sequence in 

 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 

 for the Cavium CN5860 pro-

cessor boot sequence. See 

 for default environment variables settings.
