STM32 Nucleo boards

Introduction

The STM32 Nucleo board (NUCLEO-F030R8, NUCLEO-F072RB, NUCLEO-F103RB, NUCLEO-F302R8, NUCLEO-F401RE, NUCLEO-L152RE) provides an affordable and flexible way for users to try out new ideas and build prototypes with any STM32 microcontroller lines, choosing from the various combinations of performance, power consumption and features. The Arduino™ connectivity support and ST Morpho headers make it easy to expand the functionality of the Nucleo open development platform with a wide choice of specialized shields. The STM32 Nucleo board does not require any separate probe as it integrates the ST-LINK/V2-1 debugger/programmer. The STM32 Nucleo board comes with the STM32 comprehensive software HAL library together with various packaged software examples, as well as direct access to mbed online resources at mbed.org.

5.1Cutable PCB

The STM32 Nucleo board is divided into two parts: ST-LINK part and target MCU part. The ST-LINK part of the PCB can be cut out to reduce the board size. In this case the remaining target MCU part can only be powered by VIN, E5V and 3.3V on STMicroelectronics Morpho connector CN7 or VIN and 3.3V on Arduino connector CN6. It is still possible to use the STLINK part to program the main MCU using wires between CN4 and SWD signals available on STMicroelectronics Morpho connector (SWCLK CN7 pin 15 and SWDIO CN7 pin 13).

5.2Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo boards.

The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled.

The embedded ST-LINK/V2-1 supports only SWD for STM32 devices. For information about debugging and programming features refer to UM1075 - ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32, User manual, which describes in detail all the ST-LINK/V2 features.

The changes versus ST-LINK/V2 version are listed below.

New features supported on ST-LINK/V2-1:

–USB software re-enumeration

–Virtual com port interface on USB

–Mass storage interface on USB

–USB power management request for more than 100 mA power on USB

Features not supported on ST-LINK/V2-1:

–SWIM interface

–Minimum supported application voltage limited to 3 V

There are two different ways to use the embedded ST-LINK/V2-1 depending on the jumper states (see Table 3 and Figure 5):

Program/debug the MCU on board (Section 5.2.2),

Program/debug an MCU in an external application board using a cable connected to SWD connector CN4 (Section 5.2.4).

		Table 3. Jumper states

5.2.1Drivers

		The ST-LINK/V2-1 requires a dedicated USB driver, which can be found on www.st.com for
		Windows Vista, 7 and 8. On Windows XP the ST-LINK/V2-1 driver requires WinUsb to be
		installed before using the ST-LINK/2-1 (either available from Microsoft website or included in
		the USB driver for ST-LINK/V2 for XP).
		In case the STM32 Nucleo board is connected to the PC before the driver is installed, some
		Nucleo interfaces may be declared as “Unknown” in the PC device manager. In this case
		the user must install the driver files (Figure 6), and from the device manager update the
		driver of the connected device.
Note:		Prefer using the “USB Composite Device” handle for a full recovery.
		Figure 6. Updating the list of drivers in Device Manager

5.2.2ST-LINK/V2-1 firmware upgrade

The ST-Link/V2-1 embeds a firmware upgrade mechanism for in-situ upgrade through the USB port. As the firmware may evolve during the life time of the ST-Link/V2-1 product (for example new functionality, bug fixes, support for new microcontroller families), it is recommended to visit www.st.com periodically in order to stay up-to-date with the latest firmware version.

5.2.3Using the ST-LINK/V2-1 to program/debug the STM32 on board

To program the STM32 on the board, plug in the two jumpers on CN2, as shown in red in Figure 7. Do not use the CN4 connector as this could disturb the communication with the STM32 microcontroller of the STM32 Nucleo board.

5.2.4Using ST-LINK/V2-1 to program/debug an external STM32 application

It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application. Simply remove the two jumpers from CN2 as illustrated in Figure 8, and connect your application to the CN4 debug connector according to Table 4.

Note:	SB12 NRST (target MCU RESET) must be OFF if you use CN4 pin 5 in your external
	application.
		Table 4. Debug connector CN4 (SWD)
	Pin		CN4	Designation
	1		VDD_TARGET	VDD from application
	2		SWCLK	SWD clock
	3		GND	Ground
	4		SWDIO	SWD data input/output
	5		NRST	RESET of target MCU
	6		SWO	Reserved
