General Information

Start-up

At either power-up or system reset, PPCBug performs the MPU, hardware,

and firmware initialization process (refer to MPU, Hardware, and

Firmware Initialization on page 1-5). This process includes a checksum of

the FLASH memory contents.

The following types of messages are displayed on the firmware console

during the initialization process:

PPCx Debugger/Diagnostics Release Version 4.x - xx/xx/xx/RMxx

PPCx-Bug>

At this point, PPCBug is waiting for you to enter one of the commands

described in Chapter 3, of this manual.

PPCBug may alternatively be configured via the ENV command to run

selftest and/or autoboot automatically during startup. If so, then PPCBug

will instead behave as follows:

The system pauses five seconds, during which you may terminate start-up,

and exit to the diagnostics prompt, by pressing ESC or the Break key.

The system performs the self test diagnostics if you do not terminate

system start-up. Upon successful completion of these tests, the system

pauses another five seconds. You may terminate start-up, and exit to the

diagnostics prompt, by pressing ESC or the Break key.
