The esp-idf-configdep utility works as a compiler wrapper. It lets the
compiler compile the app and checks whether -MF option was used to
generate dependency files. If yes, it checks for sdkconfig.h dependency
in those files.
Target file depending on sdkconfig.h is then scanned for all CONFIG_*
occurrences and the dependency file is altered so that the given target
file is marked as "dirty" only if the config options it actually uses
are changed.
This ensures that after a configuration update, only affected files are
rebuilt, reducing incremental build times.
The compiler launcher mechanism is changed from RULE_LAUNCH_COMPILE
(Makefile-only) to CMAKE_*_COMPILER_LAUNCHER (generator-agnostic),
enabling launcher chaining (configdep -> ccache -> compiler).
Made-with: Cursor
Add USB DFU and OTG console SOC capability flags for esp32s2, esp32s3, and esp32p4.
Use these caps in Kconfig, documentation conditionals, and idf.py DFU actions so USB support
is derived from SOC capabilities instead of hardcoded target names.
Calling idf.py size on linux target project would cause an
error. This was a problem for IDEs or build script which
often call this as the last step in the build process,
as it could mark the whole "build" as failed.
This command will allow users to resolve mismatches in default values
between sdkconfig and Kconfig according to a policy specified:
* sdkconfig: Using default values from sdkconfig (backward compatible)
* interactive: User can choose the source for every affected config
option separatedly
* kconfig: Using default values from Kconfig
This commit adds a new idf.py --preset NAME argument, which allows
selecting the CMake configuration preset with a given name.
For idf.py, selecting the preset does two things:
- sets the build directory, which is specified in the preset itself
using "binaryDir" field
- passes --preset argument to CMake configuration phase
The multi_config example is updated to illustrate how this feature is
expected to be used.
1. fix(wifi): Rename old NAN configuration to NAN-Sync
- Rename CONFIG_ESP_WIFI_NAN_ENABLE to CONFIG_ESP_WIFI_NAN_SYNC_ENABLE to indicate
the support for Synchronized NAN (Wi-Fi Aware).
- Because the original flag really controls the synchronized feature set, rename it
to CONFIG_ESP_WIFI_NAN_SYNC_ENABLE so the NAN-Sync and NAN-USD paths can be
selected independently without confusion.
2. Document esp_wifi_start requirement and fix USD examples
3. Rename nan_callbacks to nan_sync_callbacks
4. Remove the discovery_flag, clarify docs for sync vs USD flows, and add USD start/stop APIs
5. Require esp_wifi_start() before USD start
6. docs(nan): add NAN-USD application examples
7. add migration guide and hints for NAN-USD proto field
8. Improve allow_broadcast documentation
9. Add attention to the API esp_wifi_remain_on_channel
10. fix(wifi): align NAN API renames and docs for v6.0
- keep shared APIs under esp_wifi_nan_* while reserving
sync/usd names for mode-specific entry points
- clarify synchronized-cluster scope in headers, docs, and migration notes (EN/zh-CN)
- update examples for renamed helpers and WIFI_NAN_SYNC_CONFIG_DEFAULT()
- rename `wifi_nan_config_t` to `wifi_nan_sync_config_t`
11. Mark NAN-USD as esp-idf experimental feature
This changes how available ports are detected. It removes code duplication
for MacOS filtering which already is in esptool and prepares for port
prioritization to be used from esptool.
fix: allow larger buffer size for commands (especially for idf.py confserver)
