- Remove the EXAMPLE_LCD_IMAGE_SOURCE Kconfig option (embedded binary vs
file system) and always load images from LittleFS.
- Convert the PNG images into LZ4-compressed LVGL binary images (.bin)
at
build time using LVGLImage.py, and flash them to a LittleFS partition.
- Upgrade lvgl to 9.6.0 and add the espressif/lz4 component; link the
external LZ4 library into lvgl.
- Split the example: main.c focuses on the esp_lcd i80 API, while the
LVGL
porting (lvgl_port.c) and the UI (lvgl_demo_ui.c) live in separate
files.
- Rework the demo animation to use the LVGL animation engine (lv_anim)
with
easing paths instead of a manual software timer for smoother
rendering.
- Remove the embedded C image arrays (esp_logo.c, esp_text.c) and the
obsolete sdkconfig.ci.image_in_{bin,fs} variants.
Add test apps for binary size tracking:
- esp_timer size_metrics app with minimal/full sdkconfig variants
- minimal_baseline app to establish the platform binary size floor
idf-ci emits a skip pipeline containing only a fake_pass job, with no
include of test_child_pipeline.yml, when the modified files match no
buildable apps. patch_buildv2_child_pipeline.py redefined
generate_pytest_child_pipeline unconditionally, assuming the included
template supplied its tags, image and assign_test stage via keyword
merge. With the template absent, the injected job was bare: no tags,
default test stage. It was scheduled on the wrong runner and failed,
turning the allow_failure build_child_pipeline_buildv2 bridge red on
every buildv2 MR whose changes produce an empty app matrix.
Return early when a fake_pass job is present so the child pipeline is
left untouched and skips, matching the default build path. Add a unit
test for the patch script and a host_test job to run it.
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.
Keep legacy ULP apps on the CMake v1 build path while buildv2 coverage
is limited to full_subproject ULP apps.
Also add the missing esp_driver_gpio dependency to the esp_pm test app
so buildv2 dependency checks see driver/rtc_io.h explicitly.
The idf_test component was previously cleaned up but accidentally
reintroduced when adding esp32s31 support. It only contained an empty
header file (idf_performance_target.h) with no references anywhere
in the codebase.
Also removes the corresponding entry from astyle-rules.yml.
These tests enable features they do not use -- the VFS console, Wi-Fi task core pinning, and
the DS peripheral -- which shift memory layout, interrupt allocation, and peripheral access
enough to fail them. Override the unused options in each test's sdkconfig and ignore the
resulting unknown-symbol build warnings.
Add the parallel set of CI jobs that exercise the cmakev2 path end-to-end
via the IDF_BUILD_V2 shim. All jobs are gated on the `buildv2` MR label
with `allow_failure: true` so unrelated MRs do not pay for the extra
build matrix.
- `.gitlab/ci/build.yml`: add the buildv2 child build pipeline that
re-runs the full app build matrix with IDF_BUILD_V2=y, plus the
Windows buildv2 build job. The generator script injects IDF_BUILD_V2
and a PIPELINE_COMMIT_SHA suffix into each child job and broadens
target_test job filters so v1 and buildv2 artifacts upload to distinct
s3 cache paths and each child pipeline tests its own binary.
- `.gitlab/ci/host-test.yml`: add the QEMU (esp32, esp32c3) and Linux
pytest buildv2 jobs.
- `.idf_build_apps.toml`: parameterize build_dir with BUILDV2_DIR_SUFFIX
(set to _v2 only on the buildv2 pipeline).
