C APTER 2 SETTING UP T E STM32-P407 BOARD
2. Introduction to the chapter
This section helps you set up the STM3 -P407 development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior is
detailed.
2.1 Electrostatic warning
STM3 -P407 is shipped in a protective anti-static package. The board must not be exposed to high
electrostatic potentials. A grounding strap or similar protective device should be worn when
handling the board. Avoid touching the component pins or any other metallic element.
2.2 Requirements
In order to set up the STM3 -P407, the following items are required:
- 5 Vdc power supply (or JTAG or SWD, or 5V TRACE, or 5V CAN, or 5V_USB, depending on
PWR_SEL jumper position)
- SWD interface programmer
Note 1: additionally, the board can be programmed via JTAG interface but there are signals
multiplexed with the LCD and the audio, so if using JTAG interface for programming you might
need to implement a software mechanism to stop them or you might not be able to reprogram again.
Note : the board can also be programmed via the USART (RS 3 _1) connector using the built-it
bootloader application (without the need of third-party tool). This way of programming/debugging
is slow but my provide a better/cheaper solution in certain cases. The configuration is explained in
the RS 3 chapter (6.10) of the manual.
You may use a pair of the following devices for this purpose:
- ARM-JTAG-COOCOX programmer/debuuger which has both JTAG and SWD interfaces and
works natively with CooCox IDE, and Keil uVision and IAR EW via plugin
- Any of Olimex’s ARM-JTAG programmer/debugger (keeping in mind the note above)
- Any of Olimex's ARM-JTAG programmer/debugger + ARM-JTAG-SWD + Rowley CrossWorks
Also, a host-based software toolchain is required in order to program/debug the STM3 -P407
board. There are also a number of ready IDEs available like CooCox IDE, IAR Embedded
Page 7 of 3

OLIMEX© 014 STM3 -P407 user's manual
Workbench, Rowley CrossWorks, etc.
Olimex distributes a free IDE that works with our OpenOCD programmers:
https://www.olimex.com/Products/ARM/JTAG/_resources/OpenOCD/.
At the moment of writing this guide our ARM programmers/debuggers equipped with an ARM-
JTAG-SWD work fine (out-of-the-box) with Rowley CrossWorks.
2.3 Powering the board
Provide +5 V DC to the board's power jack, OR +5 V via the JTAG or TRACE connector (before
providing the power set the PWR_SEL jumper in the correct position)
Additionally the board can be powered using the PROTO AREA pads. Provide 5V to the respective
pad with the same label. Ground pad is named AGND.
On powering the board the PWR LED, the SATA4 LED and the display should turn on. The
SATA1, SATA and SATA3 LEDs must start blinking consecutively.
If measuring the current consumption it should be around 30 mA.
2.4 Prebuilt software
On arrival the board has a basic demo installed which features test of the LEDs, the LCD, the
joystick, the camera.
Note that the demo provided by Olimex LTD is the same as the demo provided for STM3 -P 07
though not optimized for the F407 processor.
IMPORTANT: If you have only a programmer with JTAG interface and you need to turn off the
peripherals using the JTAG signals press WKUP button (if there is a reset after programming you
might need to keep it pressed)! Pressing WKUP button will turn off those modules and will allow
JTAG reprogramming. T

6. Introduction to the chapter
In this chapter are presented the connectors that can be found on the board all together with their
pinout. Proto area is shown. Jumpers functions are described. Notes and info on specific peripherals
are presented. Notes regarding the interfaces are given.
6.1 JTAG connector
The 0-pin JTAG connector provides the interface for JTAG or/and SWD/TRACE
programming/debugging. It is advisable to use SWD or TRACE interface programmers.
*The JTAG TRST signal is multiplexed with the display. When using JTAG interface you will not
be able to debug the display of the board. If you wish to program the board with JTAG make sure to
hold the WKUP button when programming/debugging until you wipe the system memory or the
JTAG will not connect. This behavior is caused by the initial demo which redefines the pin to show
the display.
Another workaround is to set the bootloader jumpers so the board would attempt to boot from the
Embedded SRAM (and since it is blank, the display would not start which will allow you to debug
with the JTAG). Note this is not an issue if you use SWD interface.

6.10 RS232_1
RS 3 _1 is located on USART6/SPI3 line. This interface can be used for accessing the built-in
bootloader of STM3 F407 microcontroller. You will need DB9 male – DB9 female RS 3 cable.
You will also need a freely distributed piece of software called “Flash Loader Demo” - it can be
downloaded from the official page of the microcontroller under the “Design resources” (by the time
of writing the resource is located here: http://www.st.com/web/en/catalog/tools/PF 575 5 ) . Once
you have acquired the needed perquisites we need to set the board for bootloader mode as explained
below:
Step 0. It is good idea to revert all jumpers to default positions in the beginning
Step 1. Change jumper B0_1/B0_0 to B0_1 position (as said in the table print – “Boot Mode:
System Memory”)
Step . RST_E and BOOT0_E should be open, as per default (if they are closed; they are located
below the RS 3 connectors)
Step 3. Close TX_BOOT_E and RX_BOOT_E by soldering. They are located on the back of the
board near CAN connector.
Step 4. Download, install the Flash Loader Demo (from the STM3 F407 web page, resources
window)
Step 5. Connect RS 3 and run the Flash Loader Application, the target is STM3 F4_10 4K (check
the screenshots below).
