Thank you!! 👍

General RTOS API's maintained at Zephyr, and underlying drivers to which the APIs would connect are maintained at SoC venders like Nordic.

Thanks for the reply.

So soc specific API contained and maintained at zephyr!

No, I don't think there is anything planned like that.

Yes, NRFX drivers will be there.

Ok. I found nrfx driver included inside Zephyr Official Repo and I ran it on 52DK.

Every thing works fine and I got the expected result.

I just want to make clear for nrfx driver in zephyr.

Question: Nordic is doing/planing any work to have zephyr RTOS API level for peripheral DMA? (Not just for SPI. I meant all the peripherals with DMA).

If not, I think you guys will keep the nrfx driver. I hope getting proper answer!🤔

NRF52832 does have a SPIM (SPI Master with EasyDMA) peripheral.

You can use an overlay for the DK based on the DTS information.

As a sample, you may like to look at SPI lesson which does have overlay for 52DK (written for that particular sensor).
