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 32F723EDISCOVERY board and periodically, to stay up-to-date with the latest firmware version.

7.4 Power supply

The 32F723EDISCOVERY board is designed to be powered from a 5 V DC power source. It is possible to configure the 32F723EDISCOVERY board to use any of the sources described in the following
CN8 configuration Power connector Voltage
USB_STLINK CN1 5 V

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 32F723EDISCOVERY 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 32F723EDISCOVERY 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 32F723EDISCOVERY board asks for the 500 Two events can happen:
If the host is able to provide the required power, the enumeration finishes by a
“SetConfiguration” command and

red LED LD2 is turned ON, thus the 32F723EDISCOVERY board consumes maximum 500 mA current, but no more.
If the host is not able to provide the requested current, the enumeration fails. Therefore
the ST890 remains OFF and the STM32 part including the extension board is not powered. As a mandatory to use an
consequence the red LED LD2 remains turned OFF. In this case it is

Figure 8. CN8 (ST-LINK)
Note: In case the 32F723EDISCOVERY board is powered by a USB charger, there is no USB
enumeration, so the led Only in this specific

case, the resistor R5 needs to be soldered, to allow the board to be
powered anyway.
The LED LD2 is lit when the 32F723EDISCOVERY 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 32F723EDISCOVERY 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).

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:
18/59 DocID029990 Rev 2
Page 19
UM2140 Hardware layout and configuration
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 32F723EDISCOVERY 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.

8.4 TAG connector CN9

TAG connector is a 10-pin footprint supporting SWD mode, which shares same signals with ST-LINK: PA13 (JTMS / SWDIO), PA14 (JTCLK / SWCLK), PB3 (JTDO / SWO), PB4 (NRST).
TC2050-IDC-NL cable is used to link ST-LINK and TAG connector, so users can easily program and debug the STM32 without using any extra accessory.
