Every STM discovery / eval board comes with a ST-Link V2 on board, with one exception; the STM32VL version comes with a ST-Link V1.
SWD Header
Install Software
The st-flash and st-util tools are needed, provied by texane
Download and compile
$ cd /opt $ git clone git://github.com/texane/stlink.git stlink $ cd stlink $ ./autogen.sh $ ./configure $ make
Set enviroment variable
$ exportline="PATH=$PATH:/opt/stlink" $ if grep -Fxq "$exportline" ~/.profile; then echo nothing to do ; else echo $exportline >> ~/.profile; fi $ source ~/.profile
Add udev rules
$ sudo cp /opt/stlink/49-stlinkv*.rules /etc/udev/rules.d $ sudo udevadm control --reload-rules
ST-LinkV1 requires a bit different treatment, read the Readme.txt
Airframe.xml setup
Connect the ST-Link to the MCU. If a complete STM32Fx-Discovery board is used, CN3 jumpers need to be set. To program a external MCU, remove CN3 jumpers and connect the external MCU with the SWD header.
To use SWD via STLink as default:
Set FLASH_MODE=STLINK
Update the ST-Link to blackmagic probe
The STM32F103 (STLink MCU) can be flashed with the blackmagic's firware.
Two STLinkV2 Method
Hardware Setup:
One STLinkV2 (connected via USB) is programming the other one. Change the 4 Solder jumpers on the bottom of the target STLinkV2 from "DEFAULT" to "REVERSED".
Connections between the two STLinks
| Use | From Programmer | To Target |
|---|---|---|
| 5V | P2-5V | P2-5V |
| SWDIO | CN2-4 | CN3-2 |
| SWDCLK | CN2-2 | CN3-3 |
| GND | CN2-3 | CN3-4 |
Download and build the Firmware
git clone https://github.com/blacksphere/blackmagic cd blackmagic git submodule init git submodule update make cd src make clean make PROBE_HOST=stlink
Remove the readout protection, erase and flash
openocd -f interface/stlink-v2.cfg -f target/stm32f1x_stlink.cfg -c "init" -c "halt" -c "stm32f1x unlock 0" -c "shutdown" st-flash erase st-flash --reset write blackmagic.bin 0x8002000 st-flash write blackmagic_dfu.bin 0x8000000
Dokumentation
