RESET - Cold/Warm Reset

Command Input

RESET

Description

The RESET command allows you to specify the level of reset

operation that will be in effect when a RESET exception is detected

by the processor. A reset exception can be generated by pressing the

RESET switch on the debugger host.

Two RESET levels are available:

Use the ÒwarmÓ RESET option with caution, since using this option

will prevent the execution of the full board initialization on *ALL*

RESETs until this option is modified to ÒcoldÓ.

Control may passed to the boot routine, System Menu, or the

diagnostics prompt, according to the ENV command parameters.

Example

Set to ÒcoldÓ start.

PPC1-Bug>RESET <Return>

Cold/Warm Reset [C,W] = C? c <Return>

Execute Local SCSI Bus Reset [Y,N] = N? <Return>

Execute Local (CPU) Reset [Y,N] = N? Y<Return>

PPC1Bug Debugger/Diagnostics Release Version x.x - mm/dd/yy

COLD Start

Local Memory Found =nnnnnnnn (&nnnnnnnn)

Cold This is the standard level of operation, and is the one

defaulted to on power-up. In this mode, all the static

variables are initialized every time a reset is done.

Warm In this mode, all the static variables are preserved when a

reset exception occurs. This is convenient for keeping

breakpoints, offset register values, the target register state,

and any other static variables in the system.
