ST B-L475E-IOT01A Discovery kit

Contents

Hardware

Platform :ref:`platform_ststm32`: The STM32 family of 32-bit Flash MCUs based on the ARM Cortex-M processor is designed to offer new degrees of freedom to MCU users. It offers a 32-bit product range that combines very high performance, real-time capabilities, digital signal processing, and low-power, low-voltage operation, while maintaining full integration and ease of development.

Microcontroller STM32L475VGT6
Frequency 80MHz
Flash 1MB
RAM 96KB
Vendor ST

Configuration

Please use disco_l475vg_iot01a ID for :ref:`projectconf_env_board` option in :ref:`projectconf`:

[env:disco_l475vg_iot01a]
platform = ststm32
board = disco_l475vg_iot01a

You can override default ST B-L475E-IOT01A Discovery kit settings per build environment using board_*** option, where *** is a JSON object path from board manifest disco_l475vg_iot01a.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:disco_l475vg_iot01a]
platform = ststm32
board = disco_l475vg_iot01a

; change microcontroller
board_build.mcu = stm32l475vgt6

; change MCU frequency
board_build.f_cpu = 80000000L

Uploading

ST B-L475E-IOT01A Discovery kit supports the following uploading protocols:

  • blackmagic
  • cmsis-dap
  • jlink
  • mbed
  • stlink

Default protocol is stlink

You can change upload protocol using :ref:`projectconf_upload_protocol` option:

[env:disco_l475vg_iot01a]
platform = ststm32
board = disco_l475vg_iot01a

upload_protocol = stlink

Debugging

:ref:`piodebug` - "1-click" solution for debugging with a zero configuration.

Warning

You will need to install debug tool drivers depending on your system. Please click on compatible debug tool below for the further instructions and configuration information.

You can switch between debugging :ref:`debugging_tools` using :ref:`projectconf_debug_tool` option in :ref:`projectconf`.

ST B-L475E-IOT01A Discovery kit has on-board debug probe and IS READY for debugging. You don't need to use/buy external debug probe.

Compatible Tools On-board Default
:ref:`debugging_tool_blackmagic`    
:ref:`debugging_tool_cmsis-dap`    
:ref:`debugging_tool_jlink`    
:ref:`debugging_tool_stlink` Yes Yes
