Legacy ulp_embed_binary() call-site sources were attached directly to the CMake v2 child executable. However, the ULP runtime is linked with WHOLE_ARCHIVE through target_link_options(), which CMake emits before executable objects. This reversed the CMake v1 order, changed ULP code placement, and allowed runtime weak definitions to take precedence over legacy strong handlers.
Build the call-site sources as a dedicated static archive and place its whole-archive option before the runtime archive. Preserve the parent sdkconfig and include view, including FSM-specific include behavior, without generating a synthetic component tree.
Factor linker-specific whole-archive handling into a shared CMake v2 helper for GNU, Darwin, and ULP FSM linkers. Link the archive target normally as well so CMake tracks build and relink dependencies when a legacy ULP source changes.
Rename the internal ULP child-build marker to __ULP_BUILDV2 so component CMake files make the build-system scope explicit.
Document that the marker is currently set only by the IDF_BUILD_V2 ULP child path.
Route ulp_embed_binary() through a built-in CMake v2 default ULP project instead of generating a compatibility project with a synthetic main component.
Attach legacy ULP sources directly to the ULP executable, pass the parent component include view through the existing ULP_S_SOURCES/COMPONENT_* channel, and remove the generated legacy project templates plus the component path ownership validation bypass they required.
Update the build-system coverage to assert that the builtin child project builds and rebuilds when parent-owned ULP sources change.
Preserve all linker scripts passed to target_linker_script() so LP-core child builds keep the full esp32p4 LP ROM script set instead of only the first script.
Link the ULP runtime component as WHOLE_ARCHIVE for ULP child builds, matching the legacy helper behavior where runtime sources were added directly to the executable. This keeps strong runtime handlers such as ulp_lp_core_panic_handler from being skipped in favor of weak defaults from already-extracted archive objects.
Validated with the esp32p4 lp_core_hp_uart panic and LP-ROM pytest cases, plus the focused local/CI build_all shape for the app.
fix(bt): Fixed several issues on BR/EDR controller on ESP32-S31
Closes BTQABR2023-829, BTQABR2023-836, BTQABR2023-837, BTQABR2023-840, BTQABR2023-687, and BTQABR2023-697
See merge request espressif/esp-idf!51249
Fixed bug when BR/EDR ACL-U dynamic Tx buffer is enabled
Fixed infinite loop during connection set-up
Optimized the scheduling of SCO/eSCO and sniff events
Both newlib and picolibc headers in toolchain 16.1 declare timespec_get()
but the archives do not define it. Provide the missing C11 implementation
through esp_libc, mapping TIME_UTC to clock_gettime(CLOCK_REALTIME).
Closes https://github.com/espressif/esp-idf/issues/18889
Add SOC_DEBUG_HAVE_OCD_STUB_BINS for esp32c5, esp32c61, esp32h4,
esp32h21, esp32p4, and esp32s31. Update TEE linker scripts with
correct esp_tee_app_config offsets for the 0x3000 stub reservation
Move 7 trace-related examples (app_trace_basic, app_trace_to_plot,
esp_trace_custom_library, function_tracing, gcov, sysview_tracing,
sysview_tracing_heap_log) from examples/system/ into a dedicated
examples/system/tracing/ subdirectory for better organization.
Update all path references across documentation (en + zh_CN),
build-test-rules, CI configs, Kconfig, and component READMEs.
Configure the shared LCDCAM core clock through guarded LCD and CAM LL APIs,
and unify LCD functional clock LL calls around group IDs across supported targets.
