Management Processor Monitor
ATCA-9305 User’s Manual (10009109-07)

9.3.3 Monitor SDRAM Usage
Monitor SDRAM usage is typically around 1 MB for monitor code and stack support. Please note
that the monitor stack grows downward from below where the monitor code resides (in the
upper 512 KB). The monitor C stack will typically not grow beyond 512 KB, therefore the upper
1 MB of SDRAM is reserved for monitor use.
9.4 Monitor Recovery and Updates
This section describes how to recover and/or update the monitor, given one or more of the
following conditions:
If there is no console output, the monitor may be corrupted and need recovering (see the
Recovering the Monitor” section).
If the monitor still functions, but is not operating properly, then you may need to reset the
environment variables (see the “Resetting Environment Variables” section).
If you are having Ethernet problems in the monitor, you may need to set the serial number,
since the MAC address is calculated from the serial number variable.
The monitor has the ability to preserve (not overwrite) areas of memory defined by the pram
environment variable.
Any writes to these areas can cause unpredictable operation of the monitor.
