nRF54L15dk working with external flash and partition managed

[Vojislav]

Hi, 

I am having trouble setting up the partition manager in external flash with nRF54L15dk in NCS 3.0.0. I did not find any examples of this working. Interesting thing is that for machine_learning example application in NCS you can see nRF54H20 utilize this, but not nRF54L15dk, not sure why is that the case. 

Best regards,
Vojislav

Hello Vojislav,

I'll look into this issue from here on. I tried building the sample from the nRF Developer Academy course, and it works fine on my end. I think you may have missed updating the overlay file name provided with the solution.

In the solution, they’ve included overlays for two flash modules, one for &mx25r64 and one for &gd25wb256. You need to remove the one you're not using and rename the overlay files (both for the application and for MCUboot) accordingly. Please see the screenshot below.

I have removed the files app_gd.overlay and mcuboot_gd.overlay from the application.

You can ignore the .yml file, as it's used for Twister tests and the VS Code extension. It won't affect your build.

Kind Regards,

Abhijith

hi Menon 

Thanks for pointing this out, I was able to build the academy sample.

I will look how that can help my application and get back to you. 

Cheers,
