nRF54L15dk working with external flash and partition managed

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,
