5.4 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 STM32 user Flash memory. It also allows writing data into RAM. The
data come in via one of the 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 manufacturing. 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 the
section “Package information” of the datasheet (DS10198) available at www.st.com. 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 the www.st.com website and load "Bootloader V9.0 SRAM patch" to the
STM32, 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 the www.st.com website and load "Bootloader V9.0
CAN patch" to the STM32, following the information in readme.txt file available in the
package.

6.1 Cuttable PCB
The STM32 Nucleo board is divided into two parts: ST-LINK part and target STM32 part.
The ST-LINK part of the PCB can be cut out to reduce the board size. In this case the
remaining target STM32 part can only be powered by VIN, E5V and 3.3V on ST morpho
connector CN7 or VIN and 3.3V on Arduino connector CN6. It is still possible to use the
ST-LINK part to program the main STM32 using wires between CN4 and SWD signals
available on ST morpho connector (SWCLK CN7 pin 15 and SWDIO CN7 pin 13).
6.2 Embedded ST-LINK/V2-1
The ST-LINK/V2-1 programming and debugging tool is integrated in the STM32 Nucleo
board.
The ST-LINK/V2-1 makes the STM32 Nucleo boards mbed enabled.
The embedded ST-LINK/V2-1 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 User manual (UM1075), which describes in details all the ST-LINK/V2
features.
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:
–SWIM interface
– 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 4 and Figure 6):
•Program/debug the on-board STM32 (Section 6.2.2)
•Program/debug an MCU in an external application board using a cable connected to
SWD connector CN4 (Section 6.2.4).

6.2.1 Driver
Before connecting the Nucleo-64 board to a Windows 7, Windows 8 or Windows XP PC via
USB, a driver for ST-LINK/V2-1 must be installed. It can be downloaded from the
www.st.com website.
In case the STM32 Nucleo-64 board is connected to the PC before installing the driver, the
PC device manager may report some Nucleo interfaces as “Unknown”.
To recover from this situation, after installing the dedicated driver, the association of
“Unknown” USB devices found on the STM32 Nucleo-64 board to this dedicated driver,
must be updated in the device manager manually.
Note: It is recommended to proceed using USB Composite Device, as shown in Figure 7.
Figure 7. Updating the list of drivers in Device Manager
6.2.2 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 functionality, bug fixes, support for new microcontroller families), it is
recommended to visit www.st.com website before starting to use the STM32 Nucleo board
and periodically, in order to stay up-to-date with the latest firmware version.

6.2.4 Using ST-LINK/V2-1 to program and debug an external
STM32 application
It is very easy to use the ST-LINK/V2-1 to program the STM32 on an external application.
Simply remove the two jumpers from CN2 as illustrated in Figure 9: Using ST-LINK/V2-1 to
program the STM32 on an external application, and connect the application to the CN4
debug connector according to Table 5.
Note: SB12 NRST (target STM32 RESET) must be OFF if CN4 pin 5 is used in the external
application.

6.3 Power supply and power selection
The power supply is provided either by the host PC through the USB cable, or by an
external source: VIN (7V-12V), E5V (5V) or +3.3V power supply pins on CN6 or CN7. In
case VIN, E5V or +3.3V is used to power the STM32 Nucleo board, using an external power
supply unit or an auxiliary equipment, this power source must comply with the standard
EN-60950-1: 2006+A11/2009, and must be Safety Extra Low Voltage (SELV) with limited
power capability.
6.3.1 Power supply input from the USB connector
The ST-LINK/V2-1 supports USB power management allowing to request more than
100 mA current to the host PC.
All parts of the STM32 Nucleo board and shield can be powered from the ST-LINK USB
connector CN1 (U5V or VBUS). Note that only the ST-LINK part is power supplied before
the USB enumeration as the host PC only provides 100 mA to the board at that time. During
the USB enumeration, the STM32 Nucleo board requires 300 mA of current to the host PC.
If the host is able to provide the required power, the targeted STM32 microcontroller is
powered and the red LED LD3 is turned ON, thus the STM32 Nucleo board and its shield
can consume a maximum of 300 mA current, not more. If the host is not able to provide the
required current, the targeted STM32 microcontroller and the MCU part including the
extension board are not power supplied. As a consequence the red LED LD3 remains
turned OFF. In such case it is mandatory to use an external power supply as explained in
the next Section 6.3.2: External power supply inputs: VIN and E5V.
When the board is power supplied by USB (U5V) a jumper must be connected between pin
1 and pin 2 of JP5 as shown in Table 8.
JP1 is configured according to the maximum current consumption of the board when
powered by USB (U5V). JP1 jumper can be set in case the board is powered by USB and
maximum current consumption on U5V does not exceed 100 mA (including an eventual
extension board or Arduino shield). In such condition USB enumeration will always succeed
since no more than 100mA is requested to the PC. Possible configurations of JP1 are
summarized in Table 6.
Warning: If the maximum current consumption of the NUCLEO and its
extension boards exceeds 300 mA, it is mandatory to power
the NUCLEO using an external power supply connected to
E5V or VIN.
Note: In case the board is powered by an USB charger, there is no USB enumeration, so the led
LD3 remains set to OFF permanently and the target STM32 is not powered. In this specific
case the jumper JP1 needs to be set to ON, to allow target STM32 to be powered anyway.

6.3.2 External power supply inputs: VIN and E5V
The external power sources VIN and E5V are summarized in the Table 7. When the board is
power supplied by VIN or E5V, the jumpers configuration must be the following:
•Jumper on JP5 pin 2 and pin 3
•Jumper removed on JP1
Using VIN or E5V as external power supply
VIN or E5V can be used as external power supply in case the current consumption of the
STM32 Nucleo and extensions boards exceeds the allowed current on 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 supply the board first using VIN or E5V then
connect the USB cable to the PC. Proceeding this way ensures that the enumeration occurs
thanks to the external power source.
The following power sequence procedure must be respected:

1. Connect the jumper between pin 2 and pin 3 of JP5
2. Check that JP1 is removed
3. Connect the external power source to VIN or E5V
4. Power on the external power supply 7 V< VIN < 12 V to VIN, or 5 V for E5V
5. Check that LD3 is turned ON
6. Connect the PC to USB connector CN1
If this order is not respected, the board may be supplied by VBUS first then by VIN or E5V,
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 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).
6.3.3 External power supply input: + 3.3V
It can be of interest to use the +3.3V (CN6 pin 4 or CN7 pin 12 and pin 16) directly as power
input for instance in case the 3.3V is provided by an extension board. When the STM32
Nucleo board is power supplied by +3.3V, the ST-LINK is not powered thus the
programming and debug features are unavailable. The external power sources +3.3V is
summarized in the Table 9.
Two different configurations are possible when using +3.3V to power the board:
•ST-LINK is removed (PCB cut) or
•SB2 (3.3V regulator) and SB12 (NRST) are OFF.
6.3.4 External power supply output
When powered by USB, VIN or E5V, the +5V (CN6 pin 5 or CN7 pin 18) can be used as
output power supply for an Arduino shield or an extension board. In this case, the maximum
current of the power source specified in Table 7 must be respected.
The +3.3V (CN6 pin 4 or CN7 pin 12 and 16) can be used also as power supply output. The
current is limited by the maximum current capability of the regulator U4 (500 mA max).

6.4 LEDs
The tricolor LED (green, orange, red) LD1 (COM) provides information about ST-LINK
communication status. LD1 default color is red. LD1 turns to green to indicate that
communication is in progress between the PC and the ST-LINK/V2-1, with the following
setup:
•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
STM32 I/O PA5 (pin 21) or PB13 (pin 34) depending on the STM32 target. Refer to Table 11
to Table 23 when:
•the I/O is HIGH value, the LED is on
•the I/O is LOW, the LED is off
LD3 PWR: the red LED indicates that the STM32 part is powered and +5V power is
available.
6.5 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 the
Nucleo board. This will avoid pressure on the buttons and consequently a possible
permanent target STM32 RESET.
6.6 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.

24/69 DocID025833 Rev 11
6.7 OSC clock
6.7.1 OSC clock supply
There are four ways to configure the pins corresponding to 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 the STM32 microcontroller.
The following configuration is needed:
– SB55 OFF and SB54 ON
– 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. Refer to the
AN2867 Application note for oscillator design guide for STM32 microcontrollers.The X3
crystal has the following characteristics: 8 MHz, 16 pF, 20 ppm, and DIP footprint. It is
recommended to use 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 with 20 pF capacitors
– 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:
–SB55 ON
–SB50
OFF
– R35 and R37 removed
•HSE not used: PF0/PD0/PH0 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
the STM32 Nucleo board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on the sticker, placed on the
bottom side of the PCB.
The board marking MB1136 C-01 corresponds to a board, configured as HSE not used.
The board marking MB1136 C-02 (or higher) corresponds to a board, configured to use
ST-LINK MCO as clock input.
DocID025833 Rev 11 25/69
UM1724 Hardware layout and configuration
68
Note: For NUCLEO-L476RG and NUCLEO-L452RE the ST-LINK MCO output is not connected to
OSCIN to reduce power consumption in low power mode. Consequently NUCLEO-L476RG
and NUCLEO-L452RE configuration corresponds to HSE not used.
6.7.2 OSC 32 KHz clock supply
There are three ways to configure the pins corresponding to low-speed clock (LSE):
•On-board oscillator: X2 crystal. Refer to the Oscillator design guide for STM8S,
STM8A and STM32 microcontrollers application note (AN2867) for oscillator design
guide for STM32 microcontrollers. It is recommended to use 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 three possible default configurations of the LSE depending on the version of the
STM32 Nucleo board hardware.
The board version MB1136 C-01 or MB1136 C-02 is mentioned on the sticker placed on the
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 and C32 value update.
6.8 USART communication
The USART2 interface available on PA2 and PA3 of the STM32 microcontroller can be
connected to ST-LINK MCU, ST morpho connector or to Arduino connector. The choice can
be changed by setting the related solder bridges. By default the USART2 communication
between the target STM32 and ST-LINK MCU is enabled, in order to support virtual COM
port for mbed (SB13 and SB14 ON, SB62 and SB63 OFF). If the communication between
the target STM32 PA2 (D1) or PA3 (D0) and shield or extension board is required, SB62 and
SB63 should be ON, SB13 and SB14 should be OFF. In such case it is possible to connect
another USART to ST-LINK MCU using flying wires between ST morpho connector and
CN3. For instance on NUCLEO-F103RB it is possible to use USART3 available on PC10
(TX) and PC11 (RX). Two flying wires need to be connected as follow:
•PC10 (USART3_TX) available on CN7 pin 1 to CN3 pin RX
•PC11 (USART3_RX) available on CN7 pin 2 to CN3 pin TX

6.11 Arduino connectors
CN5, CN6, CN8 and CN9 are female connectors compatible with Arduino standard. Most
shields designed for Arduino can fit to the STM32 Nucleo boards.
The Arduino connectors on STM32 Nucleo board support the Arduino Uno V3.
For compatibility with Arduino Uno V1, apply the following modifications:
•SB46 and SB52 should be ON,
•SB51 and SB56 should be OFF to connect I2C on A4 (pin 5) and A5 (pin 6 of CN8).
Caution 1: The I/Os of STM32 microcontroller are 3.3 V compatible instead of 5 V for Arduino Uno V3.
Caution 2: SB57 should be removed before implementing Arduino shield with VREF+ power being
provided on CN5 pin 8. Refer to Table 10: Solder bridges for details on SB57.
Table 11 to Table 23 show the pin assignment of each main STM32 microcontroller on
Arduino connectors.

6.12 ST morpho connector
The ST morpho connector consists in male pin headers (CN7 and CN10) accessible on both
sides of the board. They can be used to connect the STM32 Nucleo board to an extension
board or a prototype/wrapping board placed on top or on bottom side of the STM32 Nucleo
board. All signals and power pins of the STM32 are available on ST morpho connector. This
connector can also be probed by an oscilloscope, logical analyzer or voltmeter.
Table 24 to Table 33 show the pin assignments of each STM32 on ST morpho connector.
