Using nRF Connection SDK v3.0.2 and nRF Connection SDK Toolchain v3.0.2
Create a new blank application, "Add build Configuration" for nrf54l15dk/nrf54l15/cpuapp/ns then "Generate and Build"
Build will fail with ...
C:/ncs/v3.0.2/zephyr/boards/nordic/nrf54l15dk/nrf54l15dk_nrf54l15_cpuapp_ns.dts:71:10: fatal error: nordic/nrf54l15_ns_partition.dtsi: No such file or directory
71 | #include <nordic/nrf54l15_ns_partition.dtsi>
That file does not exist.
There do not appear to be any suitable *_partition.dtsi files for the nRF54Lxx series in the 3.0.2 distribution.
Commenting out the relevant line (71) just leads to slot0 build errors instead.
Same problem occurs with the nrf54l15dk/nrf54l15/cpuapp/ns version and the 10 and 05 variants.
No build problems with 2.9.1/2.9.2, only with 3.0.2
