Configure freeRTOS project for nRF52805

[Guy L]

Hi,

Is it possible to run a freeRTOS project on nRF52805?

I've follow the instructions from "Developing for the nRF52805 with nRF5 SDK"  on the simple "blinky" example and it works fine. the problem begins when i'm trying to adjust the "blinky_RTOS" for nRF52805.

Thanks!

It's a Cortex-M4 like the other nRF52s - so no particular reason why you shouldn't be able to use freeRTOS.

Do you have any experience with using FreeRTOS on any other microcontroller(s) ?

I would suggest that nRF52 is not a good place to be getting started on FreeRTOS.

The nRF52805 is intended for small, simple applications - do you really need an RTOS at all ... ?

What problem, exactly?

We can't help to solve the problems when we have no idea what the problems are

Same problem here.

I think the latest nRF5 SDK 17.0.2 has a FreeRTOS provided port which requires FPU and it is for that reason that Nordic only targets PCA100040 (nRF52832) and not PCA10040e (nRF52810). The same problem applies to nRF52805.

My only concern is if there may be any port supporting also those smaller MCUs or if there will never be one since the nRF52805 preferred SDK is Nordic Connect.

Hi

Do you want a FreeRTOS project for the nRF52805? As awneil says, there's no reason why you shouldn't be able to use FreeRTOS here either, but I don't see why you would need an RTOS on these smaller devices.

I don't know of any plans to port the FreeRTOS projects to the smaller MCUs, as the use case is rather limited. You can contact our sales department for a detailed road map and any details on this, as we here in support don't have any information on this matter.

Seeing as this case is almost 6 months old, I would suggest creating a ticket of your own if you need further assistance and describe your issue in detail and we'll help you as soon as we can. Feel free to link to this case if you find that it is related.

Best regards,

Simon
