2.1 Embedded ST-LINK/V2-1

The ST-LINK/V2-1 programming and debugging tool is integrated on the STM32091C-EVAL evaluation 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

This feature is no more supported on ST-LINK/V2-1:

• SWIM interface

For all general information concerning debugging and programming features common between V2 and V2-1 refer to the ST-LINK/V2 in-circuit debugger/programmer for STM8 and STM32ST-LINK/V2 User manual (UM1075).

Note: It is possible to power the board via CN12 (Embedded ST-LINK/V2-1 USB connector) even if an external tools is connected to CN10 (High density SWD connector) or CN11 (SWD connector).

2.1.1 Drivers

The ST-LINK/V2-1 requires a dedicated USB driver, which can be found at the www.st.com website for Windows® 7 and 8. On Windows® XP the ST-LINK/V2-1 driver requires WinUsb to be installed before using the ST-LINK/V2-1 (either available from Microsoft website or included in the USB driver for ST-LINK/V2 for XP).

In case the STM32091C-EVAL evaluation board is connected to the PC before the driver is installed, some STM32091C-EVAL interfaces may be declared as “Unknown” in the PC device manager. In this case the user must install the driver files, and update the driver of the connected device from the device manager.

Note: Prefer using the “USB Composite Device” handle for a full recovery.

Figure 5. USB Composite Device


12/58 DocID026902 Rev 3

2.1.2 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 new functionalities, bug fixes, support for new microcontroller families), it is recommended to visit the www.st.com website before starting to use the STM32091C-EVAL board and periodically, in order to stay up-to-date with the latest firmware version.

2.2 Board power supply

STM32091C-EVAL evaluation board is designed to be powered by 5 V DC power supply and to be protected by PolyZen from wrong power plug-in event. It is possible to configure the evaluation board to use any of the following three sources for the power supply:

• 5 V DC power adapter connected to CN16 (the Power jack on the board showed as PSU on JP15 silkscreen and called E5V). The external power supply is not provided with the board.

• 5 V DC power from CN12 (the USB Type-B connector of ST-LINK/V2-1, that is showed as STlk on JP15 silkscreen and called U5V). If the USB enumeration succeeds (as explained below), the ST-LINK U5V power is enabled, by asserting the PWR_EN pin. This pin is connected to a power switch (ST890), which powers the board. This power switch features also a current limitation to protect the PC in case of short-circuit on the board. If overcurrent (more than 600 mA) happens on board, the LED LD10 is lit.

• 5 V DC power from CN7 (the extension connector for daughterboard, that is showed as D5V on JP15 silkscreen).

STM32091C-EVAL evaluation board can be powered from ST-LINK USB connector CN12 (U5V), but only the ST-LINK part has the power before USB enumeration, because the host PC only provides 100 mA to the board at that time. During the USB enumeration, the STM32091C-EVAL board asks for the 300 mA power to the host PC. If the host is able to provide the required power, the enumeration finishes by a “SetConfiguration” command and then, the power transistor U23 (ST890) is switched ON, the red LED LD5 is turned ON, thus STM32091C-EVAL board can consume maximum 300 mA current, but not more. If the host is not able to provide the requested current, the enumeration fails. Therefore the ST890 (U23) remains OFF and the STM32 part including the extension board will not be powered. As a consequence the red LED LD5 remains turned OFF. In this case it is mandatory to use an external power supply as extra power supply.

E5V (from PSU) or D5V can be used as external power supply in case the current consumption of the STM32091C-EVAL board exceeds the allowed current on the USB. In this condition it is still possible to use the USB for communication, for programming or debugging only, but it is mandatory to power the board first using E5V or D5V, then connecting the USB cable to the PC. Proceeding this way the enumeration succeeds thanks to the external power source.

The following power sequence procedure must be respected:

4. Connect jumper JP15 for PSU or D5V side

5. Check that JP18 is removed

6. Connect the external power source to PSU or D5V (daughterboard mounted)

7. Check red LED LD5 is turned ON

8. Connect the PC to USB connector CN12

DocID026902 Rev 3 13/58


57

If this order is not respected, the board may be powered by VBUS first then E5V or D5V, and the following risks may be encountered:

1. If more than 300 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. 300 mA is requested at enumeration (since JP18 must be OFF), so there is risk that the request is rejected and the enumeration does not succeed if the PC cannot provide such current. Consequently the board is not powered (LED LD5 remains OFF).

Note: In case the board is powered by a USB charger, there is no USB enumeration, so the led LD5 remains set to OFF permanently and the board is not powered. Only in this specific case the jumper JP18 needs to be set to ON, to allow the board to be powered anyway.

Figure 6 helps to understand the structure of the power source on the evaluation board.

Figure 6. Structure of the power source

The power source is selected by setting the related jumpers JP15, JP7 and JP10 as described in Table 2.

2.3 STM32 power-mode configuration

Total three power modes are supported on the board that are configured by setting the related jumpers JP5, JP6, JP8, JP9 and JP12 as described in Table 3 and in the Notes below.

• Mode1: The VDD and VDDA are connected together and powered by fixed 3.3 V.

• Mode2: The VDD and VDDA are connected together and powered by adjustable voltage from 1.65 V to 3.6 V.

• Mode3: The VDD is powered by adjustable voltage from 1.65 V to 3.6 V while VDDA is powered by fixed 3.3 V.

Note:1 JP8 allows current measurement on VDD_MCU. Current measurement is performed by replacing JP8 by an ammeter.

Note:2 JP12 allows current measurement on VDDIO2. Current measurement is performed by replacing JP12 by an ammeter.

Note:3 JP6 allows to connect analog power source VDD_ANA to the STM32 VDDA. JP6 must be opened (to disconnect VDDA from all analog power VDD_ANA which is connected to analog circuits on the board) for STM32 Idd measurement.

Note:4 LD8 is lit when VDD < 2V and in this case STM32 is not functional. LD9 is lit when VDDA < 2.4 V and in this case analogue parts in STM32F091VCT6 are not functional.

The LED LD5 is lit when the STM32091C-EVAL evaluation board is powered by the 5 V correctly.

Table 4 shows the low-voltage limitations that might apply depending on the characteristics of some peripheral components. Components might work incorrectly when the power level is lower than the limitation.

2.18 IR LED and IR receiver

The IR receiver TSOP34836 is connected to PC6 of the STM32F091VCT6 and a current around 100 mA on IR LED is driven by PB9 through transistors T4 and T5 on the board.

Note: The IR LED may be driven by PB9 directly with 20 mA current when SB20 is closed and R116 is removed.

2.19 8x USARTs

USART chain could be routed to a 2*8 header so that some jumpers could be used to connect them to demonstrate 8x USART channels in daisy chain.The data flow is showed in the below Figure 8.

Figure 8. USART data flow

At the end both data sent at USART1_TX and data received at USART_RX can be compared and validated thanks to USARTs chain on CN1.

Warning: USART1/4/8 belongs to VDDIO2 power domain and USART2/3/5/6/7 belongs to VDDIO power domain, so the same voltage level for VDDIO and VDDIO2 is needed, to demonstrate USART chain application on this header.

2.20 Display and input devices

The 2.4” color TFT LCD connected to SPI1 port of the STM32F091VCT6 and 4-general- purpose-color LEDs (LD 1,2,3,4) are available as display device. The 4-direction joystick (B3) with selection key, which connects to PA0 and supports wakeup feature, and Tamper button (B2) are also available as input devices (see Table 16).

3.6 Daughterboard extension connectors CN6 and CN7

Two 52-pin male headers CN6 and CN7 are used to connect with daughterboard or standard wrapping board to the STM32091C-EVAL evaluation board. All GPIOs are available on it. The space between these two connectors, position of power, GND and RESET pin are defined as a standard which allows developing common daughterboards for several STM32 evaluation boards. The standard width between CN6 pin 1 and CN7 pin 1 is 2700 mils (68.58 mm). Most of evaluation boards implement this standard.

Each pin on CN6 and CN7 can be used by a daughterboard after disconnecting it from the corresponding function block on the STM32091C-EVAL evaluation board. Refer to Table 22 and Table 23 for details.
