Need Zepher RTOS porting support for nRF52840 Based Application.

Hi

Unfortunately there are so many differences between the Zephyr RTOS and the nRF5 SDK that reimplementation will in any case be easier and faster than porting, as things that work in the nRF5 SDK might not work if ported directly to Zephyr. The nrfx libraries/drivers should stay the same though, so only the most basic things really need to be reimplemented if you use our drivers/libraries.

Best regards,

Simon

Hi Simon,

Once again thanks for reply.

Again i am repeating the same questing, If we want to take the Zephyr based project as Reference project and on top of that we will start our basic porting, in this manner which project is best fit for us like which sample project from Zephyr folder , Eg:     Samples/bluetooth,   Samples/application_development, Samples/basic ...etc

Basically we are expecting one ref project which is having the multi tasks and some os internal calls like memory mgmt, semaphore and mutex mechanisms usage etc...

Any way nrfx libraries/drivers should stay the same, only Zephyr related layers going to change the some of the basic things.

Could you please mention the things which we need to take care while porting to Zephyr, apart from nrfx related, it would be helpful to us.

Since you're using BLE, I would suggest choosing the BLE sample fitting your application best, and implementing the nrfx drivers you need for your application. The biggest changes are in terms of configurations, etc. as this is no longer done in an sdk_config.h file, but rather prj.conf and Kconfig files. This is better described in our nRFConnect getting started tutorial series.

You also need to note that the Zephyr RTOS doesn't use the SoftDevice, so the BLE/radio functions are somewhat different. 

You also mentioned Direction Finding earlier, which is only supported by the nRF52833, nRF52811 and nRF5340 SoCs. Not the nRF52840.

Hi Simon, 

Thanks for providing the reply.

We will use BLE Sample as a base project for our application porting.

Why we need to implement the nrfx drivers , those are part of NCS right? 

How to do configurations by prj.conf and kconfig file. 

iF We want to use the Zephyr RTOS with BLE Softdevice how we can use this  combination.

For our application we are going to use the Nrf52833 not nrf52840.

Hi

You will need to include and enable in your configs/settings the specific nRFX drivers you'd like to use in your project. For example if you need UART in your project, but you chose a project that doesn't use this by default, you'll need to add CONFIG_NRFX_UARTE0=y in your prj.conf file.

The SoftDevice from the nRF5 SDK is not compatible with the Zephyr RTOS I'm afraid. Instead the nRFConnect SDK uses either of the Bluetooth LE Controllers mentioned here for managing the BLE spec. 

Best regards,
