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

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,

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.

I will have to look into it.

Will update you accordingly.

I use the hello world project, appcore and netcore are the same project, the difference is that in the "add build configuration" interface of "board" selection, appcore project uses my own board. The netcore project uses nrf5340dk_nrf5340_cpunet.
Below is the specific code, please help me to have a look.

Hi Jianming,

Thank you for contacting DevZone at NordicSemi.

Which netcore project you are talking about? Is it some provided sample?

Are you including netcore image as a child image?

As you have not provided any information about your project/sample setup, I would recommend looking into multicore sample that works with nrf5340.

Hope it helps.

Regards,

Naeem
