3 Quick start
The STM32 Nucleo board is a low-cost and easy-to-use development platform used to
quickly evaluate and start a development with an STM32 microcontroller in LQFP64
package.
Before installing and using the product, please accept the Evaluation Product License
Agreement from www.st.com/epla.
For more information on the STM32 Nucleo boards and to access the demonstration
software, visit www.st.com/stm32nucleo.
3.1 Getting started
Follow the sequence below to configure the STM32 Nucleo board and launch the demo
software:
1. Check the jumper position on the board, JP1 off, JP5 (PWR) on U5V, JP6 on (IDD),
CN2 on (NUCLEO) selected.
2. For correct identification of all device interfaces from the host PC, install the Nucleo
USB driver available on www.st.com/stm32nucleo, prior to connecting the board
3. Connect the STM32 Nucleo board to a PC with a USB cable ‘type A to mini-B’ through
USB connector CN1 to power the board. The red LED LD3 (PWR) and LD1 (COM)
should light up. LD1 (COM) and green LED LD2 should blink.
4. Press button B1 (left button).
5. Observe how the blinking of the green LED LD2 changes according to clicks on button
B1.
6. The demo software and several software examples on how use the STM32 Nucleo
board features are available on www.st.com/stm32nucleo.
7. Develop the application using the available examples.
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
