Kernel-mode CMake builds install applications to <build>/bin. On qemu arm/riscv the target mounts them over a semihosting hostfs relative to the spawned process working directory. When the generated .config selects CONFIG_BUILD_KERNEL=y, register app_bindir=<build>/bin and exec_cwd=<build>, keeping values set in YAML.

With app_bindir configured, cmd_check resolves commands against the application binary directory first and falls back to symbol lookups over bin_debug for names that are not applications (NSH builtins like cmd_df, cmocka entries). Flat-mode behavior is unchanged. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code
Runtime checks searched the core ELF or the NSH help output, neither of which lists kernel-mode applications. Route check_cmd through CoreConfig.cmd_check when the core is a kernel build with a known application directory, so runtime checks agree with collection-time filtering. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code
With exec_cwd set, QEMU resolved a relative '-kernel' path against the spawn directory instead of the NTFC working directory it is expressed in, so boot timed out. Absolutize the image path in the qemu and sim start paths when a custom spawn directory is configured. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code
Real hardware has no hostfs, so kernel-mode applications must be shipped as a filesystem image. Add the per-core apps_image option, which generates a ROMFS image from app_bindir with genromfs after the build, and the $APPS_BINDIR and $APPS_IMG flash command placeholders. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code
Prebuilt kernel-mode images have no host application directory, so check_cmd could not resolve commands. List CONFIG_PATH_INITIAL (default /system/bin) once on the running target, cache it, and match cmd_check patterns against it with the matcher shared with AppBinDir. A failed listing is not cached and is retried. Signed-off-by: raiden00pl <raiden00@railab.me> Assisted-by: Claude Code
CMake registers application targets at configure time from .config, but kv overrides are applied after configuring, so an override enabling a new application changed .config without ever creating its build target: code-level options took effect through the .config -> config.h rule while the application never appeared in the image. Overrides can also unlock suboptions (e.g. *_PROGNAME) whose missing defaults make cmake drop the application silently. Run olddefconfig and configure again after applying overrides.
