INTRODUCTION

STM32-P107 prototype board provides easy way for developing and prototyping with the new STM32F107VCT6 connectivity line microcontroller, produced by STMicroelectronics. STM32-P107 has JTAG port for programming and debugging, USB_OTG, user button, two status LEDs, and most of the GPIOs are on extension headers where you can connect your additional circuits.

BOARD FEATURES

- CPU: STM32F107VCT6 32 bit ARM-based microcontroller with 256 KB Flash, 64 KB RAM, USB OTG, Ethernet, 10 timers, 2 CANs, 2 ADCs, 14 communication interfaces- JTAG connector with ARM 2×10 pin layout for programming/debugging- Power jack for external power supply: suitable for (6.5-9)VDC or 6VAC- USB OTG connector capable of powering the board- USB host connector- 100 Mbit/s Ethernet driver with RJ-45 connector- RS232 driver with DE-09 female connector- MiniSD card connector- UEXT connector- Two user-programmable buttons- Reset button and circuit- Two user-programmable LEDs- Power-on LED- 25 Mhz quartz crystal- Extension port connectors for many of microcontrollers pins- Prototype area- Easy-to-change PTH jumpers- Compatible with the bootloader tools provided by STM: "Flash Loader Demo" and "DfuSe Demo"- PCB: FR-4, 1.5mm ~ (0.062)", soldermask, silkscreen component print- Dimensions: (5.2×3.8)'' ~ (132×97)mm

ELECTROSTATIC WARNING

The STM32-P107 board is shipped in protective anti-static packaging. The board must not be subject to high electrostatic potentials. General practice for working with static sensitive devices should be applied when working with this board.

BOARD USE REQUIREMENTS

Cables: The cable you will need depends on the programmer/debugger you use. If you use ARM-JTAG, you will need LPT cable, if you use ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-TINY, or ARM-USB-TINY-H you will need 1.8 meter USB A-B cable, for ARM-USB-OCD and ARM-USB-OCD-H you will need RS232 cable, too.

Hardware: Programmer/Debugger – one of the Olimex ARM Programmers: ARM-JTAG, ARM-JTAG-EW, ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-OCD-TINY, ARM-USB-OCD-H.

Note that Olimex OpenOCD debuggers lack SWD interface by default. There is the adapter ARM-JTAG-SWD that adds SWD to any of the programmers/debuggers mentioned above.

Additionally you can use our ARM-JTAG-COOCOX debugger which has both JTAG and SWD interfaces and works with CooCox IDE natively and with IAR EW and Keil uVision via plug-ins.

Note the board can be programmed without a debugger using the serial port (the one with theDE-9 connector).

Software: ARM C compiler

JUMPER DESCRIPTION

STM32-P107 has a number of jumpers. They control the behavior of the board and allow modification of the default hardware connections. There are two types of jumpers – PTH ones (big ones, easy to change using a plastic cap) and SMT ones (pads that require cutting and soldering). It is safe to change the position of the PTH jumpers as long as you use one of the legal positions of the jumper. Changing the SMT jumpers, on the other hand, is not recommended – misconfiguration of the SMT jumpers might damage the board.

There are jumper tables printed at the back of the board!

PTH jumpers:

B0_0/B0_1 and B1_0/B1_1 control the boot mode.

B0_0/B0_1When this jumper is in position B0_1 – BOOT0 is connected to 3.3V, and when the jumper is in position B0_0 – BOOT0 is connected to GND.Default state is B0_0.

B1_0/B1_1When this jumper is in position B1_1 – BOOT1 is connected to 3.3V, and when the jumper is in position B1_0 – BOOT1 is connected to GND.Default state is B1_0.

VBUS, USB_D+, and USB_D- are responsible for the USB host control. The host can be routed to either the USB_OTG or the USB_HOST control.

VBUSWhen is in position “H” - connects +5V_HOST_PWR to OTG_VBUS.When is in position “O” - connects +5V_OTG_PWR to OTG_VBUS.Default state is “O”.

USB_D+When is in position “H” - connects USB_HOST_D+ to OTG_DP.When is in position “O” - connects USB_OTG_D+ to OTG_DP.Default state is “O”.

USB_D-When is in position “H” - connects USD_HOST_D- to OTG_DM.When is in position “O” - connects USB_OTG_D- to OTG_DM.Default state is “O”.

RST_E and BOOT0_E jumpers are responsible for the system memory boot mode via UART protocol.

RST_E, BOOT0_E jumpersNote that it is recommended to move those jumpers together – either both should be open or both should be closed.When both are closed RS232 boot is enabled (and also B0_0/B0_1 should be in B0/1 position). You can use Flash Load Demonstrator program provided for free by STMicroelectronics: http://www.st.com/web/en/catalog/tools/PF257525

Default states are RST_E – open; BOOT_E – open.Page 10 of 23

SMT jumpers:

The SMT jumpers are typically used for hardware measurements and hardware debugging. Please do not attempt to change the jumpers if you lack the soldering skills required.

CONNECTOR DESCRIPTIONS

JTAG

The JTAG connector is used to program and debug the board via a third-party tool. It can be used for JTAG and SWD programming and debugging. It is recommended to use with tools that have a compatible20-pin 0.1 step connector.

The JTAG connector allows the software debugger to talk via a JTAG (Joint Test Action Group) port directly to the core. Instructions may be inserted and executed by the core thus allowing STM32F107 memory to be programmed with code and executed step by step by the host software.

For more details please refer to IEEE Standard 1149.1 – 1990 Standard Test Access Port and Boundary Scan Architecture and STM32F107's datasheet and user's manual.

PWR_JACK

The board has a standard Olimex DC barrel jack with 2.0mm inner pin and 6.3mm hole. More information about the exact component might be found here: https://www.olimex.com/wiki/PWRJACK

You can supply either DC or AC voltage to power the board however be careful – if you provide more than the maximum voltage suggested, you would permanently damage the board.

The suggested voltage ranges for powering the board from the PWR_JACK are:

If you are powering the board from a DC power source – you need to provide between 6.5V and 9.0V of voltage.

If you are powering the board from an AC power source – you need to provide 6.0V of voltage.

The port can be used for DFU USB mode of the STM32F107 processor. To be able to upload data you would need a mini USB cable connected to a personal computer that runs the proper software supplied byST.

Page 13 of 23

To enter the DFU mode you would also need to set the STM32-P107's jumpers properly. Make sure all jumpers are set as per default and then change the jumper B0_0/B0_1 to position B0_1 – which means boot from system memory.

More information about the DFU USB mode might be found at the ST's web-site. By the time of writing this document more information and required files can be found at this link: http://www.st.com/web/en/catalog/tools/PF257916

You can download the archive that contains the graphical user interface for DFU connection. It is called “DfuSe Demo”. Extract it and install the software. Set the jumpers of STM32-P107 to boot from system memory. Leave the rest of the jumpers as per default. Connect the STM32-P107 board to the computer using a mini USB cable. This would show an unrecognized device in “Windows Device Manager”. Point the driver updater to the folder where “DfuSe Demo” was installed. After the driver installation the board would be recognized as “STM Device in DFU Mode”. At this point launch “DfuSe Demo” and restart the board. A properly connected board looks like in the picture below:

For more information about DFU mode refer to the official USB and ST web-sites.

RS232

The board can be programmed via the RS232 connector (serial interface). This is done without the need of an additional programming tool. However, you would need a proper serial cable or adapter to access it. You would also need to change the positions of three PTH jumpers (the rest of the jumpers should be as per default):

1. B0_0/B0_1 should be set to position B0_1 – which means boot from system memory2. RST_E should be closed3. BOOT_E should be closed

Do not confuse B0_0/B0_1 with B1_0/B1_1.

After you set the jumpers and establish the hardware connection you need to download the software provided by STMicroelectronics. It is called “Flash Loader Demonstrator”. It might be found here: http://www.st.com/web/en/catalog/tools/PF257525 – after you install the software and establish connection you can upload hex files to the board without the need of an expensive debugger. A properly recognized board in “Flash Loader Demonstrater” is shown below:

Note that this method of programming is much slower than working with a debugger. Not only the uploadspeed is low – you would need to perform hardware debugging routines to be able to track what is going on.

The layout of the port is shown on the next page:Page 15 of 23
