nrf5340 Interprocessor Communication without using OpenAMP

[martibalbi]

Hello!

I am evaluating using nrf5340 for a very simple application (literally would only be a few lines of code). In it, I want to pass some information from the network core to the application core. I know that I can signal the application core that there is new information to be picked up using IPC, but the documentation then says that it is OpenAMP that handles the exchange. However, I do not wish to include Zephyr or any kind of high level library since I prefer working straight with registers.

Therefore, what would be the way for the application core to receive correctly data from the network core?

Thank you very much in advance.

Hi,

First of all, I strongly recommend using Zephyr and our nRF Connect SDK when working with the nRF5340. http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.8.0/nrf/ug_nrf5340.html

Here is a sample that show use to use RPMsg Service: github.com/.../rpmsg_service

We don't have any examples for this. But OpenAMP uses the IPC driver in nrfx, so you could take a look at that driver: https://github.com/NordicSemiconductor/nrfx/blob/master/drivers/src/nrfx_ipc.c
