INTRODUCTION

This document describes the usage of the Broadcom DOS USH Diagnostics program (USHDIAG).

The DOS USHDIAG is a single DOS based diagnostic program that provides the necessary host based diagnostics

interface to the USH firmware.

The USH (BCM5880) has two communication interfaces: TPM (via LPC) and CV (via USB). The USHDIAG program

can communicate to the USH firmware via the TPM or CV interface. The program provides a means of extracting

diagnostic information, running diagnostic tests, upgrading firmware and enabling diagnostic debug information,. The

program is command line driven with the arguments specifying the desired diagnostic functions or download operations.

The USHDIAG uses Dell’s BIOS USB Driver for the USH CV interface.

SYNTAX

The USHDIAG is a Host command line diagnostics program which communicates to the USH firmware. The various

options passed into the program dictates the behavior of the USHDIAG.

The USHDIAG syntax is:

ushdiag [option] … [option] <CR>

•

Each option is preceded by a dash (-), with no space between the dash and the option.

•

Some options are stand alone, meaning there is no additional data. While other options have data associated

with them. If an option has data associated with it, the data is entered just after the option (e.g.: -offset 10000).

•

If an invalid option is entered, the help option is displayed, which lists all possible options.

•

Several options can be selected. The USHDIAG executes each option in a predefined order.

These options are divided into three categories (control commands, TPM commands & CV commands) and are

described below.

The USHDIAG can communicate to the USH firmware either via the TPM or CV interface. By default the USHDIAG

communicates to the USH via the TPM interface. If you wish to communicate to the USH via the CV interface you must

select the CV interface by using the CV Interface option (‘-u’ for USB interface).

CONTROL COMMAND OPTIONS

The USHDIAG provides controls to enable diagnostic debugging. These controls help in the debugging of a particular

issue by providing more information to help identify a particular problem.

This is accomplished with the following commands:

3.1

Help (-h)

This command displays the available commands and their syntax.

3.2

Verbose (-v)

This command generates additional console messages.

3.3

Pause (-p)

If the DOS console messages scroll off the screen, it is not possible to retrieve them. This command ‘pauses’ the console

output (and execution) when the console screen is full. The console and program remain ‘paused’ until any key is

pressed on the keyboard.

3.4

Repeat (-rep <num>)

This command repeats the specified diagnostic tests <num> times. The tests are repeated <num> times unless an error

occurs or a key is pressed on the keyboard. If <num> is 0, the tests are repeated forever or until an error occurs or a key

is pressed.

3.5

Log (-l <filename>)

This command directs the console messages to the specified log file.

3.6

CV Interface (-u)

By default the USHDIAG uses the TPM interface to communicate with the USH. Selecting this option forces the

USHDIAG to use the CV (or USB) interface to communicate with the USH.
