ESP32 Forum

I recently saw an article on getting started with NuttX on the ESP32 by Sara Monteiro, an embedded software engineer at Espressif. At this point I'm pretty committed to FreeRTOS for my current project, but I'm intrigued. Is there an article that compares FreeRTOS with NuttX to which you can point me, especially something that would describe the kinds of projects for which one or the other might be better?

Thanks.

Note that from what I understand, NuttX is it's own ecosystem and it's not possible to combine it with ESP-IDF. FreeRTOS on the other hand is only the RTOS component, so it needs ESP-IDF as support.

You might want to take a look at the article that got me wondering. It's at
https://medium.com/the-esp-journal/gett ... 3e1a3d182c

It purports to be by an Espressif embedded software engineer, Sara Monteiro. And the article seems to make use of the esp-idf quite a bit. Of course, the fact that FreeRTOS is pretty well integrated with the esp-idf makes me wonder how much of the esp-idf can be used with NuttX, but the article is intriguing.

from that article: "At this point, a conceptual note is very important, NuttX does not use FreeRTOS in any internal layer, only a few auxiliary tools that make up the IDF will be used for generating the binary and flashing it."

OK. So no articles of which you are aware that compare the two OS's. I'm pretty happy with FreeRTOS, but seeing an article on NuttX from an Expressif software engineer made me wonder about it.

Thanks for the reply.
