FreeRTOS

Configuration:

framework = freertos

FreeRTOS is a real-time operating system kernel for embedded devices that has been ported to 40 microcontroller platforms.

Platforms

Name	Description
CHIPS Alliance	The CHIPS Alliance develops high-quality, open source hardware designs relevant to silicon devices and FPGAs.
SiFive	SiFive brings the power of open source and software automation to the semiconductor industry, making it possible to develop new hardware faster and more affordably than ever before.

Examples

• FreeRTOS for CHIPS Alliance

• FreeRTOS for SiFive

Debugging

Debugging - “1-click” solution for debugging with a zero configuration.

Tools & Debug Probes

Supported debugging tools are listed in “Debug” column. For more detailed information, please scroll table by horizontal. You can switch between debugging Tools & Debug Probes using debug_tool option in “platformio.ini” (Project Configuration File).

Warning

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

On-Board Debug Tools

Boards listed below have on-board debug probe and ARE READY for debugging! You do not need to use/buy external debug probe.
