Diagnostic Parameters and Commands
Using diagnostics-related DO commands
FClear
Description: Clears Flash memory on the MAX unit. When the unit boots, it loads the code
and configuration from Flash memory into Dynamic Random Access Memory (DRAM). If
you want to return your unit to its factory-set defaults, you need to perform an FClear.
Usage: Enter
fclear
at the command prompt.
Example:
MAX> fclear
See Also: FSave
FRestore
Description: Restores a configuration from flash memory and loads it into DRAM on the
MAX.
Note:
The MAX unit performs an FRestore when it boots. You need to execute the command
if you have made changes to the current configuration and want to restore the configuration
stored in Flash memory.
Usage: Enter
frestore
at the command prompt.
FSave
Description: Stores the current configuration into flash memory.
Note:
When you load code with the TloadCode command, an FSave is performed
automatically before the code is uploaded. When the box boots after the upload, the MAX unit
will load the configuration stored in flash memory rather than be reset to factory default
settings.
Usage: Enter
fsave
at the command prompt.
Example:
MAX> fsave
See Also: FClear
