Baremetal Application Example and CPU setup source files.

[Frikkie Badenhorst]

Hi there, 

We are looking for an example application for the nRF5340 DK that runs a very basic baremetal application. All sample applications seems to be using the Zephyr OS. Could you please point me to such an application?

We are planning on using a different real time embedded framework than Zephyr. We thus require all the essential source files that sets up the CPU prior to the main function executing. Where can I find these files? We want to include these files directly in the IDE so that we have full control over it and can edit it if ever necessary?

Regards,

Frikkie

Hi Håkon,

Are there any update on this?

Maybe some more context on what we want to achieve:

We want to get our existing application ported to the nRF5340 application core. Our current application uses a different real time embedded framework than the Zephyr OS (which we also want to use on the 5340 application core), hence we want to get a baremetal application running first so that we can start implementing the other OS.

When it comes to the network core, like bluetooth and 802.15.4 stacks, we will use the existing Zephyr RTOS.

Hence in summary, the network core will be running the Zephyr RTOS and the application core will be running the Zephyr RTOS as the bluetooth or other stacks may require.

Is this even a possibility?

Please advise ASAP.

Thanks

Frikkie

Hi Frikkie,

 

As mentioned, we do not have any bare metal implementation examples for nRF5340. As mentioned, we do supply the startup and system files, through the nRF MDK delivery available on our website, but you will have to include Zephyr OS in your project if you use NCS.

 

If you want to setup a bare metal example, you have to do this from scratch.

 

Kind regards,

Håkon
