sakura.io Evaluation Board

Hardware

Platform ST STM32: 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 STM32F411RET6
Frequency 100MHz
Flash 1MB
RAM 128KB
Vendor sakura.io

Configuration

Please use sakuraio_evb_01 ID for board option in “platformio.ini” (Project Configuration File):

[env:sakuraio_evb_01]
platform = ststm32
board = sakuraio_evb_01

You can override default sakura.io Evaluation Board settings per build environment using board_*** option, where *** is a JSON object path from board manifest sakuraio_evb_01.json. For example, board_build.mcu, board_build.f_cpu, etc.

[env:sakuraio_evb_01]
platform = ststm32
board = sakuraio_evb_01

; change microcontroller
board_build.mcu = stm32f411ret6

; change MCU frequency
board_build.f_cpu = 100000000L

Uploading

sakura.io Evaluation Board supports the next uploading protocols:

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

Default protocol is mbed

You can change upload protocol using upload_protocol option:

[env:sakuraio_evb_01]
platform = ststm32
board = sakuraio_evb_01

upload_protocol = mbed

Debugging

Debugging - “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 Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

sakura.io Evaluation Board has on-board debug probe and IS READY for debugging. You don’t need to use/buy external debug probe.

Frameworks

Name Description
CMSIS The ARM Cortex Microcontroller Software Interface Standard (CMSIS) is a vendor-independent hardware abstraction layer for the Cortex-M processor series and specifies debugger interfaces. The CMSIS enables consistent and simple software interfaces to the processor for interface peripherals, real-time operating systems, and middleware. It simplifies software re-use, reducing the learning curve for new microcontroller developers and cutting the time-to-market for devices
Mbed Arm Mbed OS is an open source embedded operating system designed specifically for the ‘things’ in the Internet of Things. It includes all the features you need to develop a connected product based on an Arm Cortex-M microcontroller, including security, connectivity, an RTOS and drivers for sensors and I/O devices
STM32Cube STM32Cube embedded software libraries, including: The HAL hardware abstraction layer, enabling portability between different STM32 devices via standardized API calls; The Low-Layer (LL) APIs, a light-weight, optimized, expert oriented set of APIs designed for both performance and runtime efficiency
libopencm3 The libOpenCM3 framework aims to create a free and open-source firmware library for various ARM Cortex-M0(+)/M3/M4 microcontrollers, including ST STM32, Ti Tiva and Stellaris, NXP LPC, Atmel SAM3, Energy Micro EFM32 and others
