FreeRTOS Linux Port

FreeRTOS port implementation for Linux using POSIX threads. Made to test FreeRTOS projects on Linux systems.

Getting Started

Include the files inside the port folder into your FreeRTOS project.

Build the example project

git clone https://github.com/innerand/FreeRTOSLinux.git
make get_freertos
make 

Requirements

• FreeRTOS 10.2.1, other versions may work but are not tested.
• Tasks must be created with dynamic memory allocation using vTaskCreate(). Tasks with statically allocated memory are not supported.
• FreeRTOS should be compiled with a c compiler. C++ doesn't work well with pthread_cancel() which is used to end FreeRTOS tasks. This also applies to c++ functions called within a FreeRTOS task. pthread_cancel() throws an exception which is problematic e.g. within destructors or while another exception is handled. If the program aborts with terminate called without an active exception it was probably because pthread_cancel() was executed at a wrong moment. However, this port is used for CI/CD testing with Gtest/Gmock (C++) and turned out to be quite stable when all the C++ has been put into critical sections.

Usage

• FreeRTOS tasks may be interrupted at anytime. Therefore all functions that are not async-signal safe (e.g. printf()) must be put into critical sections. If the program crashes or deadlocks within syscalls, it's probably because a function hasn't been put into a critical section.
• Add an ApplicationIdleTask() to the project and put a nanosleep (without a critical section) into it. Otherwise the port will eat all your CPU time.
