ST-LINK/V2 (CN) - STM8 / STM32 Programmer & Debugger

ST-LINK/V2 (CN) - STM8 / STM32 Programmer & Debugger

The ST-LINK/V2 is an in-circuit debugger and programmer for the STM8 and STM32 microcontroller families. The single wire interface module (SWIM) and JTAG/serial wire debugging (SWD) interfaces are used to communicate with any STM8 or STM32 microcontroller located on an application board.

• STM8 applications use the USB full speed interface to communicate with STMicroelectronic's ST Visual Develop (STVD) or ST Visual Program (STVP) software.
• STM32 applications use the USB full speed interface to communicate with Atollic, IAR, Keil or TASKING integrated development environments.

Features

• 5 V power supplied by a USB connector
• USB 2.0 full speed compatible interface
• USB standard A to mini B cable
• SWIM specific features
• 1.65 V to 5.5 V application voltage supported on SWIM interface
• SWIM low-speed and high-speed modes supported

• SWIM programming speed rate: 9.7 Kbytes/s in low speed and 12.8 Kbytes/s in high speed

• SWIM cable for connection to the application via an ERNI standard vertical (ref: 284697 or 214017) or horizontal (ref: 214012) connector

• SWIM cable for connection to the application via a pin header or a 2.54 mm pitch connector

• JTAG specific features
  • 1.65 V to 3.6 V application voltage supported on the JTAG interface and 5 V tolerant inputs
  • JTAG cable for connection to a standard JTAG 20-pin pitch 2.54 mm connector
• Direct firmware update feature supported (DFU)
• Status LED which blinks during communication with the PC
• Operating temperature 0 to 50 °C

Device Drivers

While connecting the ST-LINK/V2 to the computer through USB interface, the USB driver is required and should be installed correctly first.

ST Link LED status

The LED labeled 'COM' on top of the ST-LINK/V2 shows the ST-LINK/V2 status (whatever the connection type). When the:

• LED is blinking RED: the first USB enumeration with the PC is taking place. If it keeps blinking RED, maybe the USB driver is NOT found.
• LED is RED: communication between ST-LINK/V2 and the PC is established (end of enumeration).
• LED is blinking GREEN/RED: data are being exchanged between the target and the PC.
• LED is GREEN: the last communication has been successful.
• LED is ORANGE: ST-LINK/V2 communication with the target has failed.
