Overview

You can use the factory-installed debug monitor, PPCBug, to modify certain parameters contained in the MVME240x’s Non-Volatile RAM (NVRAM), also known as Battery Backed-up RAM (BBRAM).

❏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.
