Why to go with Zephyr RTOS in nRF5340?

Hi Bruno,

Yes, we decided to start our development with Zephyr RTOS, and yeah ,as you have mentioned , it really takes more development time. The device tree seems a bit complicated to understand.

But as Nordic has mandated NCS with Zephyr for nRF5340, we started to use it.

Mohan, did you proceed any further with your considerations?

The more we progress here in our current development, the less I see Zephyr as of any advantage at all. Yes, it is too big to fail, and eventually it will work - if your project can wait a couple of years.

The mandatory Zephyr has caused us at least 6 months delay so far, and very basic functionalities are still not working in Zephyr. Our project is one year old and there are bugs we can't seem to solve unless we decide to learn the realms of Zephyr and change low level issues ourselves - after which we will have a hard time to use main Zephyr updates...

We are seriously considering to propose to our customer another 6 months delay on the project, and come up with our 'bare bone' solutions for nRF5340 with FreeRTOS or something similiar... Or maybe we should go as far as redesigning the HW to use a silicon that does not force Zephyr into their developers...

Maybe join this webinar this afternoon: https://webinars.nordicsemi.com/understand-the-nrf-connect-sdk/join

There seem to be a few nRF Connect webinars coming up:

Oh okay @awneil . From the link you mentioned Didrik Rokhaug quoted that it was not feature ready for production. What stage is it now? Are there any example implementation for DFU bootloader and mesh model like as in nRF52, as a starting point?

Yes - AIUI, Zephyr is an integral part of the nRF-Connect SDK.
