CMSIS compliant RTOS

[dotm]

Hi all.
My idea is to list all CMSIS compliant RTOS kernel.
Information about CMSIS RTOS:
http://www.keil.com/pack/doc/CMSIS/RTOS/html/index.html

RTX (proprietary CMSIS version now open source), good integration in Keil:
http://www.keil.com/pack/doc/cmsis_rtx/_overview.html

abassi RTOS (proprietary):
http://code-time.com/cortex.html
Api documentation:
http://code-time.com/pdf/Abassi%20-%20CMSIS%20API.pdf

mbed (based on RTX):
http://mbed.org/users/mbed_official/code/mbed-rtos/

RT-Thread:

RT-Thread is an open source real-time operating system for embedded devices from China, which has strong scalability

https://github.com/RT-Thread/rt-thread
wrapper:
https://github.com/RT-Thread/rt-thread/tree/master/components/CMSIS/RTOS

FreeRTOS:
This seems to be available with CMSIS wrapper.
At least it is included in the STM32Cube middleware, see here:
http://www.st.com/st-web-ui/static/active/en/resource/technical/document/user_manual/DM00105262.pdf

In the STM32CubeF4 firmware FreeRTOS is used as real time operating system through the generic CMSIS-OS wrapping layer provided by ARM

ChibiOS:
Wrapper finally available:
https://sourceforge.net/p/chibios/svn/HEAD/tree/trunk/os/common/abstractions/cmsis_os/

Using CMSIS RTOS just requires 2 extra lines in the makefile and a main.c written using the CMSIS RTOS API, see the example.

µOS++

The µOS++ IIIe (micro oh ɛs plus plus third edition) project is the third iteration of µOS++, a POSIX-like, portable, open source, royalty-free, multi-tasking real-time operating system intended for 32/64-bits embedded applications, written in C++.

StateOs

Free, extremely simple, amazingly tiny and very fast real-time operating system (RTOS) designed for deeply embedded applications. Target: ARM Cortex-M family. It was inspired by the concept of a state machine.

Wrapper:

Huawei LiteOS

Huawei LiteOS is an IoT-oriented software platform integrating an IoT operating system and middleware. It is lightweight, with a kernel size of under 10 KB, and consumes very little power — it can run on an AA battery for up to five years!

Wrapper is found in the pack to be installed with the Keil Pack Installer:

Zephyr Project

The Zephyr™ Project is a scalable real-time operating system (RTOS) supporting multiple hardware architectures, optimized for resource constrained devices, and built with safety and security in mind.

we don't have the CMSIS RTOS Layer yet but we could create it on request, of course.

Update: found a possible wrapper. Seems to be inofficial:

Have you looked at SEL4?

Presently seL4 runs on ARMv6 (ARM11), ARMv7 (Cortex A8, A9, A15) and x86 cores. Supported ARM platforms for these are the Freescale i.MX31, OMAP3 BeagleBoard, Exynos Arndale 5250, Odroid-X, Odroid-XU, Inforce IFC6410 and Freescale i.MX6 Sabre Lite.

Why should I?
Since this is not running on any cortex M devices the likehood there is a cmsis rtos wrapper available is pretty.. not.
If you can provide a link to the wrapper eg. : cmsis_os.h
I will add it to the list

is uCOS III is CMSIS compliant ?

do you have any tutorial how to create a project in Keil µVision
I will downloaded many projects from Micrium it will compile correctly however when I build new in keil it gets me lot's of error.
If anybody has step by step procedure to create project in Keil µVision IDE then please post the details it will be very help ful for me.

Can you please link to the new ChibiOS SVN repository? https://sourceforge.net/p/chibios/svn/HEAD/tree/

There's also an official GitHub mirror of the SVN: https://github.com/ChibiOS

Hi.
Good hint.,
I wanted to check if a wrapper exists first before adding it to the list, since the documentation clearly says so.
https://wiki.stmicroelectronics.cn/stm32mcu/index.php?title=THREADX_overview&oldid=17193&diff=prev#CMSIS-RTOS_API_Support
However, I could not find it in the repo. The compatibility layers are located here:
https://github.com/azure-rtos/threadx/tree/master/utility/rtos_compatibility_layers
Do I have to search a specific fork? Any Idea?
Thanks

Edit: It seems just not ready yet. Should be available in the port of ST for projects based on CubeMX

Does Azure RTOS have a cmsis RTOS api?
Azure RTOS does not provide cmsis-RTOS api natively. with st delivery, we will provide cmsis-RTOS api on top of threadx

Their repository is located here: https://github.com/STMicroelectronics/x-cube-azrtos-h7/tree/main/Middlewares/ST/threadx
But the compatibility layer is not there as it seems. Further hints are welcome!
