I'm running into issues when specifying non-secure for the build target, even for the basic Blinky sample. I created a build configuration with the nRF Connect SDK v3.4.0 and nRF Connect SDK Toolchain v3.4.0. The board target I'm trying to use is nrf7002dk/nrf5340/cpuapp/ns. I've left all the other options blank/default. I don't see any issues in the build output or flashing step that would indicate that the sample app would fail. Instead of a blinking LED, I only see the status LED lit up next to the IMCU.
Notably, flashing the exact same application as a secure app (nrf7002dk/nrf5340/cpuapp) works perfectly fine on this board, and I'm able to see the LED blink.
VS Code and the related SDKs and utilities are installed in a Ubuntu 22.04 distrobox while the host OS is Fedora Silverblue. I've also tested in a devcontainer with the same build configuration, toolchain, and SDK and ran into the same issue with non-secure apps.
Build output:
