Gotya. Let me know if you get anything. Alternatively the error log would be nice.

I've really been trying to come up with some sort of minimal reproducer by using publiclly available samples. Every time i try to use a debugger I can't even break into main() so i'm trying to take this approach. It always seems to get stuck in an infinite loop in the idle thread.

I'm currently trying something else by to trying to move my overlay and config on top of a common sample and find out where it breaks.

But the same thing didn't with nRF54L15 on the same SDK version? Gotya. Could you get me the error log you are getting? Does this project use anything in particular that stands out?

it worked fine with ncs 3.2.1.

Hi John,

[quote user=""]I have an application with the nrf52840 that was trying to port to nrf54l15 using ncs 3.2.1 but i ran into various issues. I decided to look into some samples that could help narrow down the problem. The application code is written in C++ for the most part

This previous code you are trying to port, was that made for another version of NCS? I would think some sw that worked well for a 52840 would also work for 54L15.

[quote user=""]I started with this sample[/quote]

I would recommend that you base what you create on something made by Nordic, preferably on the NCS SDK. Unfortunately there is no go-to sample directly from Nordic on how to work with C++, but there are two from Zephyr. Though I see that the sample you link to is rather straight forward, and based on the DevAcademy, so that should be fine.

Elfving

Oh, i realize I'm using the the v3.2 branch here, rather than the specific version tag, but the problem exists at the v3.2.1 tag
