ELECTROSTATIC WARNING
The STM32-P107 board s sh pped n protect ve ant -stat c packag ng. The board must not be
subject to h gh electrostat c potent als. General pract ce for work ng w th stat c sens t ve dev ces
should be appl ed when work ng w th th s board.

BOARD USE REQUIREMENTS
Cables: The cable you w ll need depends on the programmer/debugger you use. If you use ARM-
JTAG, you w ll need LPT cable, f you use ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-
TINY, or ARM-USB-TINY-H you w ll need 1.8 meter USB A-B cable, for ARM-USB-OCD and
ARM-USB-OCD-H you w ll need RS232 cable, too.
Hardware: Programmer/Debugger – one of the Ol mex ARM Programmers: ARM-JTAG, ARM-
JTAG-EW, ARM-USB-OCD, ARM-USB-OCD-H, ARM-USB-OCD-TINY, ARM-USB-OCD-H.
Note that Ol mex OpenOCD debuggers lack SWD nterface by default. There s the adapter ARM-
JTAG-SWD that adds SWD to any of the programmers/debuggers ment oned above.
Add t onally you can use our ARM-JTAG-COOCOX debugger wh ch has both JTAG and SWD
nterfaces and works w th CooCox IDE nat vely and w th IAR EW and Ke l uV s on v a plug- ns.
Note the board can be programmed without a debugger using the serial port (the one with the
DE-9 connector)
Software: ARM C comp ler

JUMPER DESCRIPTION
STM32-P107 has a number of jumpers. They control the behav or of the board and allow mod f cat on of
the default hardware connect ons. There are two types of jumpers – PTH ones (b g ones, easy to change
us ng a plast c cap) and SMT ones (pads that requ re cutt ng and solder ng). It s safe to change the
pos t on of the PTH jumpers as long as you use one of the legal pos t ons of the jumper. Chang ng the
SMT jumpers, on the other hand, s not recommended – m sconf gurat on of the SMT jumpers m ght
damage the board.
There are jumper tables pr nted at the back of the board!
PTH jumpers:
B0_0/B0_1 and B1_0/B1_1 control the boot mode.
B0_0/B0_1
When th s jumper s n pos t on B0_1 – BOOT0 s connected to 3.3V, and when the
jumper s n pos t on B0_0 – BOOT0 s connected to GND.
Default state s B0_0.
B1_0/B1_1
When th s jumper s n pos t on B1_1 – BOOT1 s connected to 3.3V, and when the
jumper s n pos t on B1_0 – BOOT1 s connected to GND.
Default state s B1_0.
VBUS, USB_D+, and USB_D- are responsible for the USB host control. The host can be
ro ted to either the USB_OTG or the USB_HOST control.
VBUS
When s n pos t on “H” - connects +5V_HOST_PWR to OTG_VBUS.
When s n pos t on “O” - connects +5V_OTG_PWR to OTG_VBUS.
Default state s “O”.
USB_D+
When s n pos t on “H” - connects USB_HOST_D+ to OTG_DP.
When s n pos t on “O” - connects USB_OTG_D+ to OTG_DP.
Default state s “O”.
USB_D-
When s n pos t on “H” - connects USD_HOST_D- to OTG_DM.
When s n pos t on “O” - connects USB_OTG_D- to OTG_DM.
Default state s “O”.
RST_E and BOOT0_E j mpers are responsible for the system memory boot mode via UART
protocol.
RST_E, BOOT0_E jumpers
Note that t s recommended to move those jumpers together – e ther both should be
open or both should be closed.
When both are closed RS232 boot s enabled (and also B0_0/B0_1 should be n B0/1
pos t on). You can use Flash Load Demonstrator program prov ded for free by
STM croelectron cs: http://www.st.com/web/en/catalog/tools/PF257525
Default states are RST_E – open; BOOT_E – open.

SMT jumpers:
The SMT jumpers are typ cally used for hardware measurements and hardware debugg ng. Please do not
attempt to change the jumpers f you lack the solder ng sk lls requ red.
3 3V_MCU_E
Enable m crocontroller 3.3V power supply
Default state s closed.
3 3V_E

CONNECTOR DESCRIPTIONS
JTAG
The JTAG connector s used to program and debug the board v a a th rd-party tool. It can be used for
JTAG and SWD programm ng and debugg ng. It s recommended to use w th tools that have a compat ble
20-p n 0.1 step connector.
The JTAG connector allows the software debugger to talk v a a JTAG (Jo nt Test Act on Group) port
d rectly to the core. Instruct ons may be nserted and executed by the core thus allow ng STM32F107
memory to be programmed w th code and executed step by step by the host software.
For more deta ls please refer to IEEE Standard 1149.1 – 1990 Standard Test Access Port and Boundary
Scan Arch tecture and STM32F107's datasheet and user's manual.

PWR_JACK
The board has a standard Ol mex DC barrel jack w th 2.0mm nner p n and 6.3mm hole. More
nformat on about the exact component m ght be found here: https://www.ol mex.com/w k /PWRJACK
You can supply e ther DC or AC voltage to power the board however be careful – f you prov de more
than the max mum 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 m n USB cable connected to a personal computer that runs the proper software suppl ed by
ST.
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 pos t on B0_1 – wh ch means
boot from system memory.
More nformat on about the DFU USB mode m ght be found at the ST's web-s te. By the t me of wr t ng
th s document more nformat on and requ red f les can be found at th s l nk:
http://www.st.com/web/en/catalog/tools/PF257916
You can download the arch ve that conta ns the graph cal user nterface for DFU connect on. It s called
“DfuSe Demo”. Extract t and nstall 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
us ng a m n USB cable. Th s would show an unrecogn zed dev ce n “W ndows Dev ce Manager”. Po nt
the dr ver updater to the folder where “DfuSe Demo” was nstalled. After the dr ver nstallat on the board
would be recogn zed as “STM Dev ce n DFU Mode”. At th s po nt launch “DfuSe Demo” and restart the
board. A properly connected board looks l ke n the p cture below:
For more nformat on about DFU mode refer to the off c al USB and ST web-s tes.

RS232
The board can be programmed v a the RS232 connector (ser al nterface). Th s s done w thout the need
of an add t onal programm ng tool. However, you would need a proper ser al cable or adapter to access t.
You would also need to change the pos t ons of three PTH jumpers (the rest of the jumpers should be as
per default):
1. B0_0/B0_1 should be set to pos t on B0_1 – wh ch means boot from system memory
2. RST_E should be closed
3. BOOT_E should be closed
Do not confuse B0_0/B0_1 w th B1_0/B1_1.
After you set the jumpers and establ sh the hardware connect on you need to download the software
prov ded by STM croelectron cs. It s called “Flash Loader Demonstrator”. It m ght be found here:
http://www.st.com/web/en/catalog/tools/PF257525 – after you nstall the software and establ sh
connect on you can upload hex f les to the board w thout the need of an expens ve debugger. A properly
recogn zed board n “Flash Loader Demonstrater” s shown below:
Note that th s method of programm ng s much slower than work ng w th a debugger. Not only the upload
speed s low – you would need to perform hardware debugg ng rout nes to be able to track what s go ng
on.
