Product marking UM2469

2 Product marking

Evaluation tools marked as "ES" or "E" are not yet qualified and therefore they are not ready to be used as reference design or in production. Any consequences deriving from such usage will not be at ST charge. In no event, ST will be liable for any customer usage of these engineering sample tools as reference design or in production.

"E" or "ES" marking examples of location:

• On the targeted STM32 that is soldered on the board (for illustration of STM32 marking, refer to the section "Package information" of the STM32 datasheet at www.st.com).

• Next to the evaluation tool ordering part number, that is stuck or silkscreen printed on the board

This board features a specific STM32 device version, which allows the operation of any bundled commercial stack/library available. This STM32 device shows a "U" marking option at the end of the standard part number and is not available for sales.

In order to use the same commercial stack in his application, a developer may need to purchase a part number specific to this stack/library. The price of those part numbers includes the stack/library royalties.

7.3 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32F7308-DK board. Compared to ST-LINK/V2 the changes are listed below.

The new features supported on ST-LINK/V2-1 are:

• 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

These features are no more supported on ST-LINK/V2-1:

• SWIM interface

• Application voltage lower than 3 V

For general information concerning the debugging and programming features that are common to both versions V2 and V2-1, refer to the ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32 user manual (UM1075).

7.3.1 Drivers

Before connecting the STM32F7308-DK board to a Windows® 7, Windows® 8 or Windows downloaded from the www.st.com website.

In case the STM32F7308-DK board is connected to the PC before installing the driver, the PC device manager may report some STM32F7308-DK board interfaces as “Unknown”. To recover from this situation, after installing the dedicated driver, the association of “Unknown” USB devices found on the STM32F7308-DK board to this dedicated driver, must be manually updated in the device manager.

Note: It is recommended to proceed using USB Composite Device, as shown in Figure 7.

7.3.2 ST-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 a new functionality, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the STM32F7308-DK board and periodically, to stay up-to-date with the latest firmware version.

7.4 Power supply

The STM32F7308-DK board is designed to be powered from a 5 V DC power source. It is possible to configure the STM32F7308-DK board to use any of the sources described in the following

Tabl e 2.

Note: The Discovery board must be powered by a power supply unit or by an auxiliary equipment

complying with the standard EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited power capability.

7.4.1 Supplying the board through the ST-LINK USB port (default setting)

To power the STM32F7308-DK board in this way the USB host (PC) gets connected with the ST-LINK USB port through a USB Type-A to Micro-B cable.

5 V DC power is provided by V LINK/V2-1 (USB 5

V power source on silkscreen “ST-LINK”, see Figure 8). If the USB enumeration succeeds (as explained below), the ST-LINK 5 V link power is enabled by asserting the PWR_ENn signal. This pin is connected to U1, a power switch powers the board. This power switch also features a current limitation to protect the PC in case of a short-circuit on the board (current demand exceeding 700

The STM32F7308-DK board can be powered from the ST-LINK USB connector CN1 (STLINK), but only the STM32F103CBT6 (U2) is powered before USB enumeration, because the host PC only provides 100 enumeration, the STM32F7308-DK board asks for the 500 events can happen:

• If the host is able to provide the required power, the enumeration finishes by a

case, the resistor R5 needs to be soldered, to allow the board to be

powered anyway.

The LED LD2 is lit when the STM32F7308-DK board is powered by the 5 V correctly.

Caution: Do not connect a PC to ST-LINK (CN1) when R5 is soldered. The PC may be damaged or the

board not powered correctly.

7.4.2 Supplying the board through a charger connected to ST-LINK

The 5 V DC power charger is connected to USB STLINK (CN1). In this case if the STM32F7308-DK board is powered by an external USB charger then the debug is not available. If the PC is connected instead of the charger, then the limitation is no more effective and the PC could be damaged (5 see

Figure 9).

7.4.3 Supplying the board from E5V (CN3 or CN12)

Figure 10. CN8 (External 5V supply)

From E5V: 5V DC power adapter connected to CN3

In this case, the STM32F7308-DK board must be powered by a power supply unit or by an auxiliary equipment complying with standard EN-60950-1: 2006+A11/2009 connected to CN3, and must be Safety Extra Low Voltage (SELV) with limited power capability (5 source on silkscreen “E5V” see

Figure 10).

V power

From E5V: 7-12V DC power from CN12 (VIN)

7-12 V DC power supply is provided by an Arduino Uno V3 compatible shield connected to CN11, CN12, CN13 and CN15 connectors.

This 7-12 V voltage (VIN) is then converted to 5 V by a LDO (U11).

Finally, the user must fit the jumper on "E5V" position on CN8 connector, to select this LDO output (E5V) as main power supply for the board (see

Figure 10).

7.4.4 Supplying the board from an external power supply through USB HS

A 5 V DC external power supply is connected to USB OTG HS Micro-AB connector CN19 (5

V power source on silkscreen “USB_HS”, refer to Figure 11).

7.4.5 Supplying the board from an external power supply through USB FS

A 5 V DC external power supply is connected to USB OTG FS Micro-AB connector CN18 (5

V power source on silkscreen “USB_FS”, see Figure 12).

Figure 12. CN8 (USB_FS)

7.5 Programming/debugging when the power supply is not from ST-LINK

It is mandatory to power the board first using CN3 (E5V) or CN12 (VIN) or CN18 (USB FS) or CN19 (USB_HS), then connecting the USB cable to the PC. Proceeding this way ensures that the enumeration succeeds thanks to the external power source.

The following power sequence procedure must be respected:

1. Connect the jumper CN8 on (E5V) or (USB_HS) or (USB_FS)

2. Connect the external power source to CN3 or CN12 or CN18 or CN19

3. Check that the red LED LD2 is turned ON

4. Connect the PC to USB connector CN1

If this order is not respected, the STM32F7308-DK Discovery board may be powered by V

first from ST-LINK and the following risks may be encountered:

BUS

1. If more than 500 mA current is needed by the board, the PC may be damaged or current can be limited by PC. As a consequence the board is not powered correctly.

2. 500 mA is requested at the enumeration: if the PC cannot provide such current, there is a risk that the request is

rejected and the enumeration does not succeed.

7.6 Clock sources

Up to 2 clock sources as described below:

• X2, 25 MHz oscillator for STM32F730I8K6 microcontroller.

• X3, 32 KHz crystal for STM32F730I8K6 embedded RTC
