6.1
Embedded ST-LINK/V2 (or V2-A) ST-LINK/V2 on STM32F4DISCOVERY or ST-LINK/V2-A on STM32F407G-DISC1 is embedded as programming and debugging tool. The embedded ST-LINK/V2 (or V2-A) supports only SWD for STM32 devices. For information about debugging and programming features refer to ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32, UM1075 User manual, which describes in details all the ST-LINK/V2 features. The changes on ST-LINK/V2-A versus ST-LINK/V2 version are listed below. New features supported on ST-LINK/V2-A: •
Virtual com port interface on USB (see Section 6.1.3: ST-LINK/V2-A VCP configuration)
•
Mass storage interface on USB
DocID022256 Rev 5
11/39 38
Hardware and layout
UM1472
Features not supported on ST-LINK/V2-A: •
SWIM interface
•
Minimum supported application voltage limited to 3 V
•
USB power management request for more than 100 mA power on USB
Known limitation: •
Activating the readout protection on ST-LINK/V2-A target, prevents the target application from running afterwards. The target readout protection must be kept disabled on ST-LINK/V2-A boards.
There are two different ways to use the embedded ST-LINK/V2 (or V2-A) depending on the jumper states (see Table 3): •
Program/debug the STM32 on board (refer to Section 6.1.4: Using ST-LINK/V2 (or V2A) to program/debug the STM32F4 on board)
•
Program/debug the STM32 in an external application board, using a cable connected to SWD connector CN2 (refer to Section 6.1.5: Using ST-LINK/V2 (or V2-A) to program/debug an external STM32 application) Table 3. Jumper states Jumper state
6.1.1
Description
Both CN3 jumpers ON
ST-LINK/V2 (or V2-A) functions enabled for on board programming (default)
Both CN3 jumpers OFF
ST-LINK/V2 (or V2-A) functions enabled for application through external CN2 connector (SWD supported)
Drivers The ST-LINK/V2 (or V2-A) requires a dedicated USB driver, which, for Windows® XP, 7 and 8, can be found on the www.st.com website. In case the STM32 Discovery is connected to the PC before the driver is installed, some Discovery 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 he must update the driver of the connected device.
Note:
Prefer using the “USB Composite Device” handle for a full recovery. Figure 5. Updating the list of drivers in Device Manager

6.1.2
Hardware and layout
ST-LINK/V2 (or V2-A) firmware upgrade The ST-LINK/V2 (or V2-A) 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 (or V2-A) product (for example new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the Discovery board and periodically, in order to stay up-to-date with the latest firmware version.
6.1.3
ST-LINK/V2-A VCP configuration The ST-LINK/V2-A supports Virtual Com Port (VCP) on U2 pin 12 (ST-LINK_TX) and U2 pin 13 (ST-LINK_RX) but these pins are not connected to an USART of the STM32F407 target STM32 for mbed support. Two solutions are possible to connect an STM32F407 USART to the VCP on the PC: •
Using an USART to USB dongle from the market connected for instance to STM32F407 USART2 available on connector P1 pin 14 (PA2: USART2_TX) and P1 pin 13 (PA3: USART2_RX).
•
Using flying wires to connect ST-LINK/V2-A Virtual com port (ST-LINK VCP on U2 pin 12 and 13) to STM32F407 USART2 (PA2 and PA3: P1 pin 14 and 13) as shown in the Figure 6 below. Figure 6. ST-LINK VCP connection to USART2

6.1.4
UM1472
Using ST-LINK/V2 (or V2-A) to program/debug the STM32F4 on board To program the STM32F4 on board, simply plug in the two jumpers on CN3, as shown in Figure 7 in red, but do not use the CN2 connector as that could disturb communication with the STM32F407VGT6 of the STM32F4DISCOVERY.

Using ST-LINK/V2 (or V2-A) to program/debug an external STM32 application It is very easy to use the ST-LINK/V2 (or V2-A) to program the STM32 on an external application. Simply remove the two jumpers from CN3, as shown in Figure 8, and connect the application to the CN2 debug connector according to Table 4.
Note:
SB11 must be OFF if CN2 pin 5 is used in the external application. Table 4. Debug connector CN2 (SWD) Pin

Power supply and power selection The power supply is provided either by the host PC through the USB cable, or by an external 5V power supply. The D1 and D2 diodes protect the 5V and 3V pins from external power supplies:

•
5V and 3V can be used as output power supplies when another application board is connected to pins P1 and P2. In this case, the 5V and 3V pins deliver a 5V or 3V power supply and power consumption must be lower than 100 mA.
•
5V can also be used as input power supplies e.g. when the USB connector is not connected to the PC. In this case, the STM32F4DISCOVERY board must be powered by a power supply unit or by auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability.
LEDs •

On board audio capability The STM32F4 uses an audio DAC (CS43L22) to output sounds through the audio mini jack connector. The STM32F4 controls the audio DAC through the I2C interface and processes digital signals through an I2S connection or an analog input signal. •
•
6.6
The sound can come independently from different inputs: –
ST MEMS microphone (MP45DT02): digital using PDM protocol or analog when using the low pass filter
–
USB connector: from external mass storage such as a USB key, USB HDD, and so on
–
Internal memory of the STM32F4
The sound can be output in different ways through audio DAC: –
Using I2S protocol
–
Using the STM32F4 DAC to analog input AIN1x of the CS43L22
–
Using the microphone output directly via a low pass filter to analog input AIN4x of the CS43L22
USB OTG supported The STM32F4 is used on this board to only drive the USB OTG full speed. The USB microAB connector (CN5) allows the user to connect a host or device component, such as a USB key, mouse, and so on. Two LEDs are dedicated to this module:
6.7
•
LD7 (green LED) indicates when VBUS is active
•
LD8 (red LED) indicates an overcurrent from connected device
Motion sensor (ST MEMS LIS302DL or LIS3DSH) Two different versions of motion sensors (U5 in schematic) are available on the board depending on the PCB version. The LIS302DL is present on board MB997B (PCB revision B) and the LIS3DSH is present on board MB997C (PCB rev C). The LIS302DL and LIS3DSH are both ultra-compact low-power three-axis linear accelerometers. The motion sensor includes a sensing element and an IC interface able to provide the measured acceleration to the external world through the I2C/SPI serial interfaces. The LIS302DL has dynamically user selectable full scales of +-2g/+-8g and it is capable of measuring acceleration with an output rate of 100Hz to 400Hz. The LIS3DSH has ±2g/±4g/±6g/±8g/±16g dynamically selectable full-scale and it is capable of measuring acceleration with an output data rate of 3.125 Hz to 1.6 kHz. The STM32F4 controls this motion sensor through the SPI interface.
