Board target with and without ns on nRF54L15DK

[Archiet]

Hi there!

May I know why sample codes cannot be run on nRF54L15DK when board target "nrf54l15dk/nrf54l15/cpuapp" is chosen?

Yet, everything is fine when nrf54l15dk/nrf54l15/cpuapp/ns" is selected.

Thanks!

Hi there! what do you mean by "delete the build directory" Is that removing the entire build and  create a new one? 

[Jørgen Holmefjord]

Yes, delete the folder where the build files are stored. In your case, this looks like "C:/Users/morri/nrf/direct_test_mode/build/" according to your build log.

Tried but still showing the same thing.

Hi there!

I reinstalled toolchain v2.9.0. Now I can have both target boards "nrf54l15dk/nrf54l15/cpuapp" and "nrf54l15dk/nrf54l15/cpuapp/ns" for my application.

If I use my own hardware design instead of the DK, may I ask if I can still use the two target boards above? Anything I need to pay attention to ?

Thanks!

Great to hear that a reinstall of the toolchain resolved the problem.

You can typically use the DK targets for initial testing, but since they describe the hardware on our boards, it may include things not present on your board and missing parts that you have on your board. I would recommend creating your own board targets as soon as you have you own hardware, see this DevAcademy lesson: https://academy.nordicsemi.com/courses/nrf-connect-sdk-intermediate/lessons/lesson-3-adding-custom-board-support/
