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.

Note:
The monitor has the ability to preserve (not overwrite) areas of memory defined by the pram environment
variable.
variable.
Caution:
Any writes to these areas can cause unpredictable operation of the monitor.
MONITOR RECOVERY AND UPDATES
This section describes how to recover and/or update the monitor, given one or more of the
following conditions:
following conditions:
• If there is no console output, the monitor may be corrupted and need recovering (see
• 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.
