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

Pinout with Apogee connector

Install Software

INFO Latest version is now available on github in this repository: https://github.com/stlink-org/stlink, with all install instructions (from packages or from sources with CMake). Instruction below are for legacy code and should be removed soon.

The st-flash and st-util tools are needed, provided by texane

Download and compile 

$ cd /opt
$ git clone git://github.com/texane/stlink.git stlink
$ cd stlink
$ ./autogen.sh
$ ./configure
$ make

Set environment 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 firmware.

Two STLinkV2 Method

Use one STLink to flash another

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

Connections [Header-Pin]
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

Documentation

Black Magic Discovery from Esden <-- This also describes how to remove the read out protection.
embdev.net page

BMP Method

Use a BMP to flash a STLink

Transfer the solder jumpers from "Default" to "Reversed" and build the firmware as described above.
Connect the BMP to the CN2 header (see Pinout above).

Start gdb, erase the option bytes and flash BMP 

(gdb) target extended-remote /dev/ttyACM0
(gdb) mon swdp_scan
(gdb) att 1 
(gdb) mon option erase
(gdb) load /dir/to/blackmagic
(gdb) load /dir/to/blackmagic_dfu
(gdb) detach

The option bytes do not cover the Readout Protection (RDP), but the RDP is disabled anyhow...

Error at loading a new image after removing RDP 

Error erasing flash with vFlashErase packet

If this occurs powercycle the target (disconnect and reconnect the 3V3 connection), swd scan, attach and try loading the image again. Usually the reset of the RDP requires a flash erase (done by mon option erase) and reset.

Probably this can also be done via gdb.

Clones

There are also a lot of different Chinese clones out there. Most with an identical MCU as the original STLinkV2, some with an STM32F101.

It seems that each clone has its own programming pinout, so better double check (continuity tester) than to release the magic smoke...

Most (all?) should work with the "stlink" target from Blackmagic Probe, since they probably use the same firmware from the original STLinkV2.

Red PCB

Seems to work with the standard stlink BMP image.

  • STM32F103C8T6

Programming header (1.27mm, populated on the images) from the Mini USB to the Pin header (right to left on the image), used for programming the onboard MCU.

This has not the same hardware as https://github.com/blacksphere/blackmagic/issues/62 , but the same MCU, seems that this has just an other PCB.
