1 Getting started
1.1 Package contents
The following items are supplied in the Flash loader demonstrator package:
1.1.1 Software contents
1.
STBLLIB.dll : a dynamic link library implementing the system memory bootloader protocol and the COM communication APIs.2.
Files.dll : a dynamic link library implementing the needed file manipulation APIs to load and store binary, hexadecimal and motorola S19 files.3. STMicroelectronics flash loader.exe: a wizard application that provides the high-level
operations that can be performed by the user.
1.1.2 Hardware contents
This tool is designed to work with all STMicroelectronics devices that support the system
memory bootloader protocols. For more details, please visit the STMicroelectronics website
(https://www.sodocs.net/doc/857884614.html,) and refer to the application note AN2606: “STM32F101xx and
STM32F103xx system memory boot mode”.
1.2 System requirements
In order to use the Flash loader demonstrator with the Windows operating system, a recent
version of Windows, such as Windows 98, Millennium, 2000, XP or Vista, must be installed
on the PC.
The version of the Windows OS installed on your computer may be determined by right-
clicking on the “My Computer” icon on the desktop, then clicking on the “Properties” item in
the displayed pop-up menu. The OS type is displayed in the “System Properties” dialog box
under the “System” label as shown in Figure 1.
UM0462Getting started Figure 1.System Properties dialog box
For the communication, you need to verify that you have an available COM port(RS232) as
one COM port is required for system connection.
T o check that you have an available communication port, right-click on the “My Computer”
icon on the desktop and select “Properties” from the pop-up menu. The “System Properties”
dialog box appears. Click on the “Hardware” tab, and then on the “Device manager” button
to display the system hardware configuration. Available COM ports are grouped under the
”Ports (COM & LPT)” node in the hardware tree as shown in Figure2.

1.3 Flash loader demonstrator installation
1.3.1 Software
installation
Run the UM0462.exe file: the InstallShield Wizard will guide you to install Flash loader
demonstrator application on your computer. When the software is successfully installed,
click on the “Finish” button.
1.3.2 Hardware
installation
Connect the device to a spare COM port on your PC.
2 User interface description
The Flash loader demonstrator is designed as a wizard application. It is structured into five
steps, the:
●welcome page
●connection settings
●device information
●operation choice
●operation progress
Step 1
Run the Flash loader demonstrator from the “Programs” menu (connection to the device has
not been made yet) then, make sure that the device is connected to your PC and reset it to
restart the system memory bootloader code. The Welcome window shown in Figure3
appears.
If all is ready click “Next” to continue.

Step 2
The second step consists in selecting the connection settings. Select the desired UART
settings (port name, baud rate, data bits, parity and stop bits and timeout) as shown in
Figure4. The default configuration is automatically set.
Ensure that the boot configuration pins are set correctly, then reset the device and click
“Next” to continue. If a connection has been established, the wizard moves to the next step,
otherwise a message box is displayed that indicates the error that occurred.

Step 3
In this step the connection has been established and communication has started.
The Wizard displays the available device information such as the target ID or the number of times the read protection is disabled/enabled.
Select the target name in the target combobox as shown in Figure5, then click on “Next” to continue.

Step 4
At this step, select the requested operation –Erase, Download or Upload– and set the
related parameters:
●Erase
–Select the “All” button to erase the whole memory
–Select the “Selection” button to customize the Erase operation. Click on the
“Selection” button to display the memory mapping dialog window, then check the
pages to be erased and click “Ok”.
●Download
–Click the related browse button to open a binary, hexadecimal or S19 Motorola file.
If the loaded file is a binary file, the download address is the start address of the first
page and the “@” field is still editable to accept changes.
If the loaded file is a hexadecimal or an S19 motorola file, the download address is
the start address of the first record in the file, and the “@” field is read-only.
–Check the “Verify” check box to launch the verification process when the Download operation is finished.
–Check “Jump to the user program” to launch the downloaded program.
–Check the “Optimize download duration” to filter FFs packets (256 bytes).
–Check ”Enable read protection after download” to activate the Flash memory read protection.
●Upload
–Click the related browse button to select which binary, hexadecimal or S19 motorola file will store the uploaded data.
Note:Erase and Download operations can be performed only if the write protection is disabled.
Consequently, the software will automatically disable the write protection before launching
the operation.
For Upload operations, the software will automatically disable the read protection before
launching the operation.

Step 5
The last Wizard page shows the operation progress: it gives the size of the data to be
downloaded or uploaded, the percent completed and the duration of the operation as
illustrated in Figure7.
●In case of success, the progress bar is green colored. If an error occurs, the bar turns
red and the error is displayed.
●To stop the operation click the “Cancel” button.
●If the user program is successfully executed and
–the “Jump to the user program” check box was checked in the previous step, the communication with the system memory bootloader is lost. Consequently, the
“Back” button is disabled to avoid the launch of another operation.
–If the “Jump to the user program” check box was not checked in the previous step, the “Back” button remains active and it is possible to return to the previous step to
select the same or a different operation.
