VPD and ENV Commands
Two common tasks for which you need the factory-installed debug
monitor, EPPCBug, are:
❏
Using the EPPCBug command VPD to view board-specific
information that is stored in the VPD (Vital Product Data)
EPROM on the MBX board.
❏
Using the EPPCBug command ENV to edit configurable
EPPCBug parameters in the MBX board’s NVRAM.
The VPD and ENV commands are both described in the EPPCBug
Firmware Package User’s Manual (listed in
). Refer to that manual for general information about their
use and capabilities.
The following topics present a brief introduction to VPD and ENV, along
with the EPPCBug parameters that can be configured with the ENV
command.
VPD—Display Vital Product Data
The VPD command displays the board configuration data, which is
resident within a serial EEPROM located on the MBX board. The serial
EEPROM contains various elements that correspond to specific
operational parameters of the board. The following example shows the
board structure for the MBX embedded controller:
Product Identifier
: MBX
Manufacturing Assembly Number : 01-w3269F21B
Serial Number
: 2677405
Product Configuration Options : 000000000000000
Internal Clock Speed (Hertz) : 02625A00 (&40000000)
External Clock Speed (Hertz) : 02625A00 (&40000000)
