Introduction

Welcome to the amazon-freertos wiki!

• This wiki describes our FreeRTOS products, how to use, use cases, technical information, and more.
• We support some devices of RX, RE, and RL78 family.
  • If you have Renesas Starter Kit+ for RX65N-2MB, you can find quick start guide into Amazon Web Services FreeRTOS certified hardware platform.
  • In the future, there may be more families to be supported.
• Now we are trying translating this wiki to English.

Important Notice!

• This repository is now deprecated.
  • https://github.com/renesas/amazon-freertos#-deprecated
• Now Renesas is developing new iot-reference repository on:
  • https://github.com/renesas/iot-reference-rx
    • Maybe after consolidating this repo for whole of Renesas devices, we would use...
      • https://github.com/renesas/iot-reference-renesas (now considering)
• Please visit the URL above if you would like to use FreeRTOS 202210.01-LTS or later.

How to clone

1. clone the master branch
   • git clone https://github.com/renesas/amazon-freertos.git
2. change directory to the master branch
   • cd amazon-freertos
3. check out the release tag like
   • git checkout v202002.00-rx-1.0.0
4. update the submodules like
   • git submodule update --init --recursive
5. Please rename from amazon-freertos to afr if you would use RTOS configuration features on SmartConfigrator.
   • (this issue will be fixed at next e2 studio version from 2020-07)

How to import demo or create new project

• Sorry, under construction. Please refer to application notes in our device's web page in Renesas Web.

About FreeRTOS

• FreeRTOS has traditionally only had real-time OS processing.
• However, since it has been managed by Amazon Web Services since 2018, the distribution now includes code for AWS connectivity called IoT Libraries.
• For the sake of convenience, we call them as follows:
  • "FreeRTOS(with IoT Libraries)": FreeRTOS with IoT Libraries
  • "FreeRTOS(Kernel Only)": Real-time OS part only, it's as before 2018.
• Initially, "Amazon FreeRTOS", which is was officially called by Amazon, means "FreeRTOS(with IoT Libraries)", but this has been consolidated into the "FreeRTOS" brand name.
• When "Amazon FreeRTOS" is mentioned in this wiki, it can be read as "FreeRTOS(with IoT Libraries)".

Distribution scheme

AWS Led qualification version

• AWS is always maintaining whole of master source code at:
  • https://github.com/aws/amazon-freertos
• You can download separated/configured for each MCU vendors specific IDE projects from FreeRTOS console:
  • https://docs.aws.amazon.com/freertos/latest/userguide/freertos-ocw.html
• This is latest version of Amazon FreeRTOS implementation.
• RX65N RSK is champion case for AWS Led qualification for Renesas.

Partner Led qualification version

• Partner (MCU vendor) is always maintaining for specific MCU boards (optional against AWS Led qualification boards) related code.
  • The URL below includes renesas qualified boards:
    • https://devices.amazonaws.com/search?kw=renesas&page=1
      • You can access source code download link ">>source code access" on each pages.
        • ">>source code access" link exists if board link would have "Qualified for FreeRTOS" mark.
          • 
• This may not be latest version of Amazon FreeRTOS implementation.
• This version exists in specific branch like:
  • https://github.com/renesas/amazon-freertos/releases/tag/v202002.00-rl78-1.0.3
    • click: 287ad67 link
      • jump to specific commit onto the branch named "rl78_pkcs_test".
