In versions >= 3.0.0, the folder structure of FreeRTOS-Plus-TCP has changed and the files have been broken down into smaller logically separated modules. This change makes the code more modular and conducive to unit-tests. Additionally, the source files have been moved to source directory. This change requires modification of project(s) to include the modified source files and directories.
If you wish to continue using the older source code organization, a script is provided to generate the folder structure similar to this.
Note: After running the script, while the .c files will have same names as the pre V3.0.0 source, the files in the include directory will have different names and the number of files will differ as well. This should, however, not pose any problems to most projects as projects generally include all files in a given directory.
For running the script, you will need Python version > 3.7. You can download/install it from here.
Once python is downloaded and installed, you can verify the version from your terminal/command window by typing python --version.
To run the script, you should switch to the FreeRTOS-Plus-TCP directory that was created using the Cloning this repository step above.
And then run python <Path/to/the/script>/GenerateOriginalFiles.py.
The easiest way to use FreeRTOS-Plus-TCP is to start with the pre-configured demo application project (found in this directory). That way you will have the correct FreeRTOS source files included, and the correct include paths configured. Once a demo application is building and executing you can remove the demo application files, and start to add in your own application source files. See the FreeRTOS Kernel Quick Start Guide for detailed instructions and other useful links.
Additionally, for FreeRTOS-Plus-TCP source code organization refer to the Documentation, and API Reference.
FreeRTOS+TCP V2.3.2-LTS-Patch-2 source code(.c .h) is part of the FreeRTOS 202012.04 LTS release.

This repository contains the FreeRTOS-Plus-TCP repository and a number of supplementary libraries for testing/PR Checks. Below is the breakdown of what each directory contains:
- tools
- This directory contains the tools and related files (CMock/uncrustify) required to run tests/checks on the TCP source code.
- tests
- This directory contains all the tests (unit tests and CBMC) and the dependencies (FreeRTOS-Kernel/Litani-port) the tests require.
- source/portable
- This directory contains the portable files required to compile the FreeRTOS-Plus-TCP source code for different hardware/compilers.
- source/include
- The include directory has all the 'core' header files of FreeRTOS-Plus-TCP source.
- source
- This directory contains all the [.c] source files.
At this time it is recommended to use BufferAllocation_2.c in which case it is essential to use the heap_4.c memory allocation scheme. See memory management.
The FreeRTOS Kernel Source is in FreeRTOS/FreeRTOS-Kernel repository, and it is consumed by testing/PR checks as a submodule in this repository.
The version of the FreeRTOS Kernel Source in use could be accessed at ./test/FreeRTOS-Kernel directory.
The test/cbmc/proofs directory contains CBMC proofs.
To learn more about CBMC and proofs specifically, review the training material here.
In order to run these proofs you will need to install CBMC and other tools by following the instructions here.
