FreeRTOS alternatives

Postby Deouss » Fri Apr 06, 2018 3:33 pm

I just noticed a wide variety of real-time operating systems out there.

Here is wiki list:
https://en.wikipedia.org/wiki/Compariso ... ng_systems

When I visited a couple of websites - the features of those were very impressive
I wonder if there is some better faster alternative and if anyone tried it.

These are listed with Xtensa support:

https://www.zephyrproject.org/
http://www.riot-os.org/ (crazy minimal resources of 5Kb !!)

Nothing that is usable in terms of having full chip/board support. Zephyr may get there eventually.

This was noted a month or so ago:

This indicates a version of Amazon FreeRTOS running on ESP32 at some future date.

Zephyr and NuttX both have some level of ESP32 support.

There is work in progress internally to make the WiFi & Bluetooth libraries easier to integrate into different RTOSes, via an abstraction layer. We're keen to see third party RTOSes work well on ESP32. :)
