diagnostic for the correct mode.
2. Test Sets marked with an asterisk (*) are not available on PPCBug
release 3.1 and earlier.Overview
You can use the factory-installed debug monitor, PPCBug, to modify
certain parameters contained in the PowerPC board’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, listed in Appendix D, Related
Documentation. 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.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
PowerPC board. The board structure for the PowerPC board is as shown in
the following example for an MVME2600:
The parameters that are quoted are left-justified character (ASCII) strings
padded with space characters, and the quotes (") are displayed to indicate
the size of the string. Parameters that are not quoted are considered data
strings, and data strings are right-justified. The data strings are padded
with zeroes if the length is not met.
The Board Information Block is factory-configured before shipment.
There is no need to modify block parameters unless the NVRAM is
corrupted.
Refer to the Programmer’s Reference Guide, listed in Appendix D,
Related Documentation, for the actual location and other information
about the Board Information Block.
Refer to the PPCBug Firmware Package User's Manual for a description
of CNFG and examples.ENV – Set Environment
Use the ENV command to view and/or configure interactively all PPCBug
operational parameters that are kept in Non-Volatile RAM (NVRAM).
Refer to the PPCBug Firmware Package User’s Manual for a description
of the use of ENV. Additional information on registers in the Universe
ASIC that affect these parameters is contained in your PowerPC board
programmer’s reference guide.
Listed and described below are the parameters that you can configure
using ENV. The default values shown were those in effect when this
publication went to print.
Configuring the PPCBug Parameters
The parameters that can be configured using ENV are:
Bug or System environment [B/S] = B?
Field Service Menu Enable [Y/N] = N?
B Bug is the mode where no system type of support is
displayed. However, system-related items are still
available. (Default)
S System is the standard mode of operation, and is the
default mode if NVRAM should fail. System mode is
defined in the PPCBug Firmware Package User’s
Manual.
Y Display the field service menu.
N Do not display the field service menu. (Default)
