9.3.1 Power-up/Reset Sequence
The ATCA-9305 monitor follows the boot sequence in Figure 9-2 before auto-booting the
operating system or application software. At power-up or board reset, the monitor performs
hardware initialization, diagnostic routines, autoboot procedures, free memory initialization,
and if necessary, invokes the command line. See Fig.
Figure 3-4 for the Cavium CN5860
processor boot sequence. See Table 9-6 for default environment variables settings.
