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







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

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.
