* Add hello world project for Vitis. * Working hello world program. * Remove the call to ps7_init(). * Demo moved from the XSDK project to Vitis is now compiling - not tried running yet though. * Blink is printing out in blinky demo. * Adjust the priorities of the demo tasks to enable them to run at once. Update blocktim.c so it stores the line on which an error was detected in the error occurred variable rather than just setting the variable to true. * Add launch configuration file. Remove unused definitions from FreeRTOSConfig.h. Edit the comments that describe what the demo does. * Revert changes to blocktim.c, which should have been in a separate PR. * Correct header comments in new files. * Update headers for core checks. * Third attempt at getting headers through the commit checks - copy headers from other files is not enough. * Still trying to get core checks to pass. * Update lexicon.txt * Correct spelling in Cortex-A9 QEMU main.c.

The FreeRTOS 202112.00 release adds the Fleet Provisioning for AWS IoT library and the Sigv4 library. Additionally, the update includes an example demonstrating the use of the Fleet Provisioning library, as well as a modification to the HTTP S3 download demo to demonstrate the Sigv4 library. This release also includes CBMC proofs for all public and private functions in the OTA Update library. The version of mbed TLS used in corePKCS11 and in demos has been updated.
Getting started
The FreeRTOS.org website contains a FreeRTOS Kernel Quick Start Guide, a list of supported devices and compilers, the API reference, and many other resources.
Getting help
You can use your Github login to get support from both the FreeRTOS community and directly from the primary FreeRTOS developers on our active support forum. The FAQ provides another support resource.
Cloning this repository
This repo uses Git Submodules to bring in dependent components.
Note: If you download the ZIP file provided by the GitHub UI, you will not get the contents of the submodules. (The ZIP file is also not a valid git repository)
If using Windows, because this repository and its submodules contain symbolic links, set core.symlinks to true with the following command:
git config --global core.symlinks true
In addition to this, either enable Developer Mode or, whenever using a git command that writes to the system (e.g. git pull, git clone, and git submodule update --init --recursive), use a console elevated as administrator so that git can properly create symbolic links for this repository. Otherwise, symbolic links will be written as normal files with the symbolic links' paths in them as text. This gives more explanation.
To clone using HTTPS:
git clone https://github.com/FreeRTOS/FreeRTOS.git --recurse-submodules
Using SSH:
git clone git@github.com:FreeRTOS/FreeRTOS.git --recurse-submodules
If you have downloaded the repo without using the --recurse-submodules argument, you need to run:
git submodule update --init --recursive
Repository structure
This repository contains the FreeRTOS Kernel, a number of supplementary libraries including the LTS ones, and a comprehensive set of example projects. Many libraries (including the FreeRTOS kernel) are included as Git submodules from their own Git repositories.
Kernel source code and example projects
FreeRTOS/Source contains the FreeRTOS kernel source code (submoduled from https://github.com/FreeRTOS/FreeRTOS-Kernel).
FreeRTOS/Demo contains pre-configured example projects that demonstrate the FreeRTOS kernel executing on different hardware platforms and using different compilers.
Supplementary library source code and example projects
FreeRTOS-Plus/Source contains source code for additional FreeRTOS component libraries, as well as select partner provided libraries. These subdirectories contain further readme files and links to documentation.
FreeRTOS-Plus/Demo contains pre-configured example projects that demonstrate the FreeRTOS kernel used with the additional FreeRTOS component libraries.
Previous releases
Releases contains older FreeRTOS releases.
FreeRTOS Lab Projects
FreeRTOS Lab projects are libraries and demos that are fully functional, but may be experimental or undergoing optimizations and refactorization to improve memory usage, modularity, documentation, demo usability, or test coverage.
Most FreeRTOS Lab libraries can be found in the FreeRTOS-Labs repository.
A number of FreeRTOS Lab Demos can be found in the FreeRTOS Github Organization by searching for "Lab" or following this link to the search results.
coreMQTT Agent Demos
The FreeRTOS/coreMQTT-Agent-Demos repository contains demos to showcase use of the coreMQTT-Agent library to share an MQTT connection between multiple application tasks.
The demos show a single MQTT connection usage between multiple application tasks for interacting with AWS services (including Over-the-air-Updates, Device Shadow, Device Defender) alongside performing simple Publish-Subscribe operations.
