Introduction

This document describes the demonstration user interface that was developed to illustrate the use of the STMicroelectronics device firmware upgrade library. A description of this library, including its application programming interface, is contained in the “DfuSe application programming interface” document and installed with the DfuSe software.

Getting started

1.1 System requirements
In order to use the DfuSe demonstration with the Windows operating system, a recent version of Windows, such as Windows 98SE, Millennium, 2000, XP, or VISTA, must be
installed on the PC.
The version of the Windows OS installed on your PC may be determined by right- clicking on the “My Computer” icon on the desktop, then clicking on the “Properties” item in the displayed PopUpMenu. The OS type is displayed in the “System Properties” dialog box under the “System” label in the “General” tab sheet (see Figure 1).

Figure 1. System properties dialog box

1.2 Package contents
The following items are supplied in this package:
Software contents

1. STTube driver consisting of the two following files:
   – STTub30.sys: Driver to be loaded for demo board.
   – STFU.inf: Configuration file for the driver.

2. DfuSe_Demo_V3.0_Setup.exe: Installation file which installs the DfuSe applications and source code on your computer.

Hardware contents
This tool is designed to work with all STMicroelectronics devices which support the Device Firmware Upgrade via a USB interface. For more details, please contact your ST
representative or visit the ST website (http://www.st.com).

1.3 DfuSe demonstration installation
1.3.1 Software installation

Run the DfuSe_Demo_V3.0_Setup.exe file: the InstallShield Wizard will guide you to install DfuSe applications and source code on your computer. When the software is successfully installed, click the “Finish” button. You can then explore the driver directory.
The driver files are located in the “Driver” folder in your install path (C:\Program files\STMicroelectronics\DfuSe).
The source code for the Demo application and DfuSe library is located in the “C:\Program Files\STMicroelectronics\DfuSe\Sources” folder.
Documentation is located in the “C:\Program Files\STMicroelectronics\DfuSe\Sources\Doc” folder.

1.3.2 Hardware installation

• Connect the device to a spare USB port on your PC.

• The “Found New Hardware Wizard” then starts. Select the “Install from a list or specific location” as shown below and then click “Next”.

• Select “Don’t search. I will choose the driver to install” as shown below and then click “Next”.
  

• If a driver is already installed, the model list will show the compatible hardware models, else click “Have Disk…” to locate the driver files.
  

• In the “Install From Disk” dialog box, click “Browse…” to specify the driver files location, the driver directory is located in your install path (C:\Program files\STMicroelectronics\DfuSe\Driver), then click “OK”.
  The PC autoselects the correct INF file, in this case, STFU.INF. Once Windows has found the required driver.INF file, the compatible hardware model will be displayed in the model list. Click “Next” to proceed.
  

• When Windows is performing the driver installation, a warning dialog will be displayed indicating that the driver has not passed Windows logo testing, click “Continue Anyway” to continue.
  

• Windows should then display a message indicating that the installation was successful.
  Click “Finish” to complete the installation.

DFU file

Users that have purchased DFU devices require the ability to upgrade the firmware of these devices. Traditionally, firmware is stored in Hex, S19 or Binary files, but these formats do not contain the necessary information to perform the upgrade operation, they contain only the actual data of the program to be downloaded. However, the DFU operation requires more information, such as the product identifier, vendor identifier, Firmware version and the Alternate setting number (Target ID) of the target to be used, this information makes the upgrade targeted and more secure. To add this information, a new file format should be used, to be called the DFU file format. For more details refer to the “DfuSe File Format Specification” document (UM0391).

User interface description

This section describes the different user interfaces available in the DfuSe package and explains how to use them to perform DFU operations such as Upload, Download and
firmware file management.

3.1 DfuSe demonstration
Firmware upgrades need to be able to be performed without any special training, even by novice users. Hence, the user interface was designed to be as robust and simple to use as possible (see Figure 9). The numbers in Figure 9 refer to the description in Ta bl e 1 listing the available controls in the DfuSe Demonstration interface.

Table 1. use demo dialog box description

one currently used.
A Compatible HID device is an HID class device providing the HID detach feature (USAGE_PAGE OxFF0O and USAGE_DETACH 0x0055) in its report descriptor.
Example:
Oxa1, Ox00, // Collection(Physical)
0x06, Ox00, OxFF, // Vendor defined usage page – OxFP00 0x85, 0x80, // REPORT_ID (128)
0x09, 0x55, // USAGE (HID Detach)
0x15, Ox00, // LOGICAL_MINIMUM (0)
0x26, OxFF, Ox00, // LOGICAL_MAXIMUM (255)
0x75, 0x08, // REPORT_SIZE (8 bits)
0x95, Ox01, // REPORT_COUNT (1)
Ox131, 0x82, // FEATURE (Data,Var,Abs,Vol)
OxCO, // END_COLLECTION (Vendor defined)
2| Device identifiers for DFU mode; PID, VID and Version.
3| Device identifiers for Application mode; PID, VID and Version.
4| Send Enter DFU mode command. Target will switch from Application to DFU mode or send an HID Detach if the device is a compatible HID device.
5| Send Leave DFU mode command. Target will switch from DFU to Application mode.
6| Memory mapping, Double-click each item to view more details about the memory part.
7| Choose the destination DFU file, the uploaded data will be copied into this file.
8| Start Upload operation.
9| Size of the transferred data during the current operation (Upload/Upgrade).
10| Duration time of the current operation (Upload/Upgrade).
11| Available targets in the loaded DFU file.
12| Choose the source DFU file, the downloaded data will be loaded from this file.
13| Start upgrade operation (Erase then download).
14| Verify if data was successfully uploaded.
15| Show the progress of the operation.
16| Abort current operation.
17| Exit application.

If the microcontroller in use in an STM32F105xx or an STM32F107xx, the DfuSe demo shows a new feature that consists in reading the option byte data over the exported “Option byte” memory part. A double click on the related item in the memory map (Item 6 in Ta bl e 1 /Figure 9) opens a new dialog box that displays the read option bytes. You can use this box to edit and apply your own configuration (see Figure 10).
The tool is able to detect the capabilities of the selected memory part (read, write and erase). In case of an unreadable memory (readout protection activated), it indicates the
memory read status and prompts to ask whether to deactivate the read protection or not.

3.2 DFU file manager
3.2.1 “Want to do” dialog box
When the DFU file manager application is executed, the “Want to do” dialog box appears, and the user has to choose the file operation he wants to do. Select the first Radio button to generate a DFU file from an S19, Hex, or Bin file, or the second to extract an S19, Hex, or Bin file from a DFU file (see Figure 11). Select the “I want to GENERATE a DFU file from S19, HEX, or BIN files” radio button if you want to generate a DFU file from S19, Hex, or Binary files.
Select the “I want to EXTRACT S19, HEX, or BIN files from a DFU one” radio button if you want to extract an S19, Hex, or Binary file from a DFU file.

3.2.2 File generation dialog box
If the first choice was selected, click the OK button to display the “File Generation dialog box”. This interface allows the user to generate a DFU file from an S19, Hex, or Bin file.

Table 2. File generation dialog box description

Because S19, Hex and Bin files do not contain the target specification, the user must enter the Device properties (VID, PID, and version), the Target ID and the target name before generating the DFU file.

3| Start address of the loaded file
4| Add file to the file list
5| Delete file from the file list
6| File list
7| Confirm file selection
8| Cancel and exit operation

3.2.3 File extraction dialog box
If the second choice in the “Want to do” dialog box was selected, Click the OK button to display the “File extraction” dialog box. This interface allows you to generate an S19, Hex, or Bin file from a DFU file.
