Issue with nRF54L15DK Board and Secure OpenThread CLI Build

[AllWhy]

Hi everyone,

I'm experiencing an issue with my nRF54L15DK board.

When I build the OpenThread CLI sample with the /ns configuration, everything works as expected. However, when I try to build the secure version, the build completes successfully, but after flashing it to the DK board, there's no indication that the program is running—no logs, no output, nothing.

Has anyone encountered this issue or knows how I could fix it?

Thanks in advance!

Hi,

The sample works fine when I run it out of the box on the nRF54L15 DK.

Please provide the following information:

• The nRF Connect SDK version you are using
• The version of your nRF54L15 DK. You should find this on a sticker on the DK.
• Have you made any changes to the sample or SDK files?
• Are you adding any configurations, e.g., snippets, when building the sample?

Best regards,
Marte
