ICSP Wiring (ARM Cortex-M)

 

In-Circuit Serial Programmer (ICSP) 

ST-Link devices are almost essential when developing software for the STM32 MCUs. They are relatively cheap and easily available.

They roughly fall into two different categories. ST themselves make a number of them and they all work quite well.

Description (OEM)

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.

ST-LINK/V2 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.

Connecting your debugger:

This small guide will explain how to connect your debugger to your development board. There are two commonly used connectors which expose only the SWD (Serial Wire Debug) interface or the full JTAG interface.

Connection Wiring (Chinese):

The easiest way to connect your development board to your debugger is by using the 4-pin SWD header, if present. This header is usually a male dupont header, but female headers are also used. The header exposes a ground pin, a +3.3V pin, a clock pin, and a data pin.

The table below provides in details of which pins to connect:

Note: There is no particular order in which these pins are arranged.

Warning: Do not connect the +3.3V pin if you are powering your board externally, as most Chinese development boards do not have any protection on the power pins. This may cause damage your board, debugger or PC.

Connection Wiring (OEM):

If your development board does not have a 4-pin SWD header, it most likely does have a 20-pin JTAG header. This connector exposes all the pins needed for full JTAG support. This includes the pins a SWD header would expose. Refer to the image below for an overview of a typical ARM JTAG header

The table below provides in details of which pins to connect:

Warning: Do not connect the +3.3V pin if you are powering your board externally, as most Chinese development boards do not have any protection on the power pins. This may cause damage your board, debugger or PC.

Connecting to GPIO pins:

If you have a development board that does not have a SWD or JTAG header, you can also connect your debugger to some specific GPIO ports. This is essentially the same as connecting your debugger via a SWD or JTAG header, although a bit more cumbersome.

The table below provides in details of which pins to connect:

Warning: Do not connect the +3.3V pin if you are powering your board externally, as most Chinese development boards do not have any protection on the power pins. This may cause damage your board, debugger or PC.
