![]() ![]() Refer to Hardware versions for connection details. Pins are available on the ST-LINK to connect the JTAG/SWD signals. The USB device is mounted on the host PC and ready to be used. Rules must then be added into /etc/udev/rules.d.Īll information and files for installing the udev rules are provided in the STSW-LINK007 package available from (see stsw-link007\AllPlatforms\StlinkRulesFilesForLinux\Readme.txt file).Ī JTAG/SWD link is available from the USB link provided by the ST-LINK. Users must be granted with rights for accessing ST-Link USB devices. The driver is automatically installed by the toolsets supporting ST-LINK. The USB driver for the debugger can differ depending of the PC operating system:Ī driver must be installed before connecting ST-LINK to a Windows® 7, Windows® 7 8, or Windows® 10 PC via the USB. The serial communication port uses standard CDC ACM USB Class, which is usually present by default on all PC operating systems. Two USB drivers are associated to ST-LINK, depending of ST-LINK version: one for the debugger itself, and one for the serial communication port from ( ST-LINK/V2-1). To find out the ST-LINK version that is embedded in your ST board, refer to the Category:STM32 MPU boards page, and then select your hardware board.ģ Getting started 3.1 Installing the USB driver įor details about the different versions, please refer to technical note of ST-LINK derivatives. Several versions of ST-LINK exist: ST-LINK/V1, ST-LINK/V2, ST-LINK/V2-A, ST-LINK/V2-B, ST-LINK/V2-1 and STLINK-V3SET. ![]() SWD/JTAG: debug protocol for STM32 microcontrollers and microprocessors.SWIM: debug protocol for STM8 microcontrollers.ST-LINK can support different debug protocols depending on ST-LINK hardware version and on its embedded firmware version: It can be either embedded on ST boards or provided as standalone dongle. ST-LINK is a USB device and has to be connected to a PC host. ![]() The ST-LINK is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. 3.3 Connecting UART port (from ST-LINK/V2-1). ![]()
