3.2 System requirements
- Windows OS (XP , 7, 8)
- USB type A to Mini-B USB cable
3.3 NUCLEO-L476RG bootloader limitations
Boot from system Flash memory results in executing bootloader code stored in the system Flash memory protected against write and erase. This allows in-system programming (ISP), that is, flashing the MCU user Flash memory. It also allows writing data into RAM. The data come in via one of communication interfaces such as USART, SPI, I²C bus, USB or CAN. Bootloader version can be identified by reading Bootloader ID at the address 0x1FFF6FFE. The STM32L476RGT6 part soldered on the NUCLEO-L476RG main board is marked with a date code corresponding to its date of manufacture. STM32L476RGT6 parts with the date code prior or equal to week 22 of 2015 are fitted with bootloader V 9.0 affected by the
limitations to be worked around, as described hereunder. Parts with the date code starting from week 23 of 2015 contain bootloader V 9.2 in which the limitations no longer exist. To locate the visual date code information on the STM32L476RGT6 package, refer to its datasheet (DS10198) available on www.st.com, section Package Information. Date code related portion of the package marking takes Y WW format, where Y is the last digit of the year and WW is the week. For example, a part manufactured in week 23 of 2015 bares the date code 5 23. Bootloader ID of the bootloader V 9.0 is 0x90. The following limitations exist in the bootloader V 9.0: 1. RAM data get corrupted when written via USART/SPI/I2C/USB interface Description: Data write operation into RAM space via USART, SPI, I²C bus or USB results in wrong or no data written. Workaround: To correct the issue of wrong write into RAM, download STSW-STM32158 bootloader V 9.0 patch package from www.st.com and load "Bootloader V9.0 SRAM patch" to the MCU, following the information in readme.txt file available in the package. 2. User Flash memory data get corrupted when written via CAN interface Description: Data write operation into user Flash memory space via CAN interface results in wrong or no data written. Workaround: To correct the issue of wrong write into Flash memory, download STSW-STM32158 bootloader V 0.9 patch package from www.st.com and load "Bootloader V9.0 CAN patch" to the MCU, following the information in readme.txt file available in the package

5.2 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled. 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: –S W I M i n t e r f a c e – Minimum supported application voltage limited to 3 V
- Known limitation: – Activating the readout protection on ST -Link/V2-1 target prevents the target application from running afterwards. The target readout protection must be kept disabled on ST-Link/V2-1 boards. There are two different ways to use the embedded ST-LINK/V2-1 depending on the jumper states (see Table 3 and Figure 4):
- 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).

5.3.2 External power s upply inputs: VIN and EV5
Table 5. JP1 configuration table
- Connect the jumper between pin 2 and pin 3 of JP5.
- Check that JP1 is removed.
- Connect the external power source to VIN or E5V.
- Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for E5V.
- Check that LD3 is turned ON.
- Connect the PC to USB connector CN1.
Table 6. External power sources Table 7. Power-related jumper VIN or E5V is used as power source when JP5 is set as shown below.
Hardware layout and configuration UM1724 1. If more than 300 mA current is needed by the board, the PC may be damaged or the current supply can be limited by the PC. As a consequence the board is not powered correctly. 2. 300 mA is requested at enumeration (since JP1 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 power supplied (LED LD3 remains OFF).
5.3.3 External power supply input: + 3V3
- ST-LINK is removed (PCB cut), or
- SB2 (3V3 regulator) & SB12 (NRST) are OFF.
5.3.4 External pow er supply output
current of the power source specified in Table 6 needs to be respected. current is limited by the maximum current capability of the regulator U4 (500 mA max).
5.4 LEDs
- Slow blinking Red/Off: at power-on before USB initialization
- Fast blinking Red/Off: after the first correct communication between the PC and ST- LINK/V2-1 (enumeration)
- Red LED On: when the initialization between the PC and ST-LINK/V2-1 is complete
- Green LED On: after a successful target communication initialization
- Blinking Red/Green: during communication with target
- Green On: communication finished and successful.
- Orange On: Communication failure User LD2: the green LED is a user LED connected to Arduino signal D13 corresponding to MCU I/O PA5 (pin 21) or PB13 (pin 34) depending on the STM32 target. Please refer to Table 10 to Table 21.
- When the I/O is HIGH value, the LED is on.
- When the I/O is LOW, the LED is off. LD3 PWR: the red LED indicates that the MCU part is powered and +5V power is available.

5.5 Push buttons
B1 USER: the user button is connected to the I/O PC13 (pin 2) of the STM32 microcontroller. B2 RESET: this push button is connected to NRST, and is used to RESET the STM32 microcontroller. Note: The blue and black plastic hats that are placed on the push buttons can be removed if necessary, for example when a shield or when an application board is plugged on top of NUCLEO. This will avoid pressure on the buttons and consequently a possible permanent target MCU RESET.
5.6 JP6 (IDD)
Jumper JP6, labeled IDD, is used to measure the STM32 microcontroller consumption by removing the jumper and by connecting an ammeter.
- Jumper ON: STM32 microcontroller is powered (default).
- Jumper OFF: an ammeter must be connected to measure the STM32 microcontroller current. If there is no ammeter, STM32 microcontroller is not powered.OSC clock
5.6.1 OSC clock supply
There are four ways to configure the pins corresponding to external high-speed clock external high-speed clock (HSE):
- MCO from ST-LINK: MCO output of ST-LINK MCU is used as input clock. This frequency cannot be changed, it is fixed at 8 MHz and connected to PF0/PD0/PH0- OSC_IN of STM32 microcontroller. The following configuration is needed: – SB55 OFF – SB16 and SB50 ON – R35 and R37 removed
- HSE oscillator on-board from X3 crystal (not provided): for typical frequencies and its capacitors and resistors, refer to STM32 microcontroller datasheet. Please refer to the AN2867 for oscillator design guide for STM32 microcontrollers. 9SL8000016AFXHF0 manufactured by Hong Kong X'tals Limited. The following configuration is needed: – SB54 and SB55 OFF – R35 and R37 soldered – C33 and C34 soldered – SB16 and SB50 OFF
- Oscillator from external PF0/PD0/PH0: from an external oscillator through pin 29 of the CN7 connector. The following configuration is needed: –S B 5 5 O N –S B 5 0 OFF
UM1724 Hardware layout and configuration – R35 and R37 removed
- HSE not used: PF0/PD0/PH1 and PF1/PD1/PH1 are used as GPIO instead of Clock The following configuration is needed: – SB54 and SB55 ON – SB16 and SB50 (MCO) OFF – R35 and R37 removed There are two possible default configurations of the HSE pins depending on the version of NUCLEO board hardware. The board version MB1136 C-01 or MB1136 C-02 is mentioned on sticker placed on bottom side of the PCB. The board marking MB1136 C-01 corresponds to a board, configured for HSE not used. The board marking MB1136 C-02 (or higher) corresponds to a board, configured to use ST- LINK MCO as clock input. Note: For NUCLEO-L476RG the ST-L ink MCO output is not connected to OSCIN to reduce power consumption in low power mode. Consequently NUCLEO-L476RG configuration corresponds HSE not used.
5.6.2 OSC 32 kHz clock supply
There are three ways to configure the pins corresponding to low-speed clock (LSE):
- On-board oscillator: X2 crystal. Please refer to the AN2867 for oscillator design guide for STM32 microcontrollers.ABS25-32.768KHZ-6-T manufactured by Abracon corporation.
- Oscillator from external PC14: from external oscillator through the pin 25 of CN7 connector. The following configuration is needed: – SB48 and SB49 ON – R34 and R36 removed
- LSE not used: PC14 and PC15 are used as GPIOs instead of low speed Clock. The following configuration is needed: – SB48 and SB49 ON – R34 and R36 removed There are two possible default configurations of the LSE depending on the version of NUCLEO board hardware. The board version MB1136 C-01 or MB1136 C-02 is mentioned on sticker placed on bottom side of the PCB. The board marking MB1136 C-01 corresponds to a board configured as LSE not used. The board marking MB1136 C-02 (or higher) corresponds to a board configured with on- board 32kHz oscillator. The board marking MB1136 C-03 (or higher) corresponds to a board using new LSE crystal (ABS25) and C26, C31 & C32 value update.
