ESP32 Forum

Hi all,

I think it is very interested if Zephyr supports ESP32.
Do you guys have the same idea with me? And does Espressif have any plan for this?

Thank you.

Howdy,
Can you post a description of "What is Zephyr?" and ideally some links to where we can read about it on the Internet? I for one don't know what Zephyr is.

We have a whole bunch of small RTOSses that would be in theory interesting to run on the ESP32: MyNEWT, Zephyr, NuttX, ... We are looking at all of them, but in all probability a fair few of them will not be implemented by us. We do plan on making it possible for others to support any OS the ESP32 is capable off: the idea is that we will shim the OS-dependent portions of the WiFi and BT libraries, and make the rest of the hardware entirely documented.

Yeah, that is a good news.

Event Zephyr is not supported by Espressif officially, the ESP32 fans (include me) can do it if we have enough information from hardware documents.
Thank you

Hi kolban,

It is a RTOS for IoT devices. Link is: https://www.zephyrproject.org/

I've been noticing there is a lot of support developing around zephyr. Lots of developments from all kinds projects/companies/communities. Might be the place to be.

Zephyr does look good indeed, unfortunately there is no support for multiprocessor systems there right now.

Maybe they need to be formally introduced to esp32...

https://jira.zephyrproject.org/browse/ZEP-323

I ended up creating another topic, but preliminary port to ESP32 has been submitted for code review: https://github.com/zephyrproject-rtos/zephyr/pull/517

There's still a whole lot missing, but I'm quite excited for the progress.

Is there anything out there that can compare to Jorge Aparicio's RTFM? Its IMHO the natural design for memory-constrained devices. Shared memory, multitasking, events, hardware assisted scheduling, verifiably safe by virtue of Rust.
