Overview

You can use the factory-installed debug monitor, PPCBug, to modify certain parameters contained in the PrPMC800/800ET’s Non-Volatile RAM (NVRAM), also known as Battery Backed-up RAM (BBRAM). NVRAM is located in the last 32K of flash bank A on the PrPMC800/800ET.

The Board Information Block in NVRAM contains various elements concerning operating parameters of the hardware. Use the PPCBug command CNFG to change those parameters.

Use the PPCBug command ENV to change configurable PPCBug parameters in

NVRAM.

The CNFG and ENV commands are both described in the PPCBug Firmware Package User’s Manual. Refer to that manual for general information about their use and capabilities.

The following paragraphs present additional information about CNFG and ENV that is specific to the PPCBug debugger, along with the parameters that can be configured with the ENV command.

Note Boards without NVRAM use the last 32K of flash bank A as substitute storage space. In these cases, there is no protection against user code being programmed over in this area.

CNFG – Configure Board Information Block

Use this command to display and configure the Board Information Block, which is resident within the NVRAM. The board information block contains various elements detailing specific operational parameters of the PrPMC800/800ET. The board structure for the PrPMC800/800ET is as shown in the following example:

Board (PWA) Serial Number

= “xxxxxxx

Board Identifier

= “PrPMC800-xxxx

Artwork (PWA) Identifier

= “01-w3649FxxD

MPU Clock Speed
