Questions about custom nrf5340 dts

[mingjkl]

I created a new dts folder for nrf5340 appcore. The application works fine on the project, but I find netcore is not working properly. I found that the BOARD_ENABLE_CPUNET option is missing from appcore kconfig compared to nrf5340dk. I tried to copy the Kconfig file from nrf5340dk into my dts folder and enabled this option, but netcore still didn't work properly. Is there anything I haven't configured?

The netcore project uses the nrf5340dk netcore dts file.

Hi Jianming,

Thank you for being patient.

What you mean by "DTS Folder"? I can not find any board folder in your project.

Did you mean "using an overlay" as I can see an overlay file for the CPUAPP core.

So I modified the project configuration and the overlay file, and I am able to build, flash and see the output from both of the cores.

Here is what I am getting (I am connected to both COM ports through putty).

Let me know if this is what you are looking for or something else.

Hi Naeem Maroof,

Thank you for your patient reply.

DTS file in /boards/arm/em5340_v1.

You can find it by going back to the root directory.

Hi Jianming,

Why your DTS folder a level above your project folder?

Have you followed some tutorial or guide to design custom board?

Here is a webinar from Nordic about custom development which you can follow if you wish to: Custom Development

There could be configuration problems, but I will have to do and see.

Regards,

Naeem
