Contains startup code, crash handling and additional Esp32-specific support code, including the ESP-IDF SDK.
If you want to tune ESP-IDF to your needs you should run:
make SMING_ARCH=Esp32 sdk-menuconfig
Followed by:
make
The following variables may need to be changed if tools are installed in a different location, or if multiple versions are installed. By default, the most current version will be used.
.. envvar:: ESP32_COMPILER_PATH
Location of xtensa compiler toolchain
.. envvar:: ESP32_ULP_PATH
Location of ULP compiler toolchain
.. envvar:: ESP32_OPENOCD_PATH
Location of ESP32 version of Open OCD JTAG debugging tools.
.. envvar:: ESP32_PYTHON_PATH
Location of ESP-IDF python.
An empty ESP IDF project is built which generates a set of libraries and headers which the framework can then be built against.
The project is located in project/{SMING_SOC}
.
The code for this project is copied from sdk/project
.
The default configuration settings are obtained from sdk/config
and written
to project/{SMING_SOC}/sdkconfig.defaults
.
When sdk-menuconfig
is run, the project/{SMING_SOC}/sdkconfig
is modified.
This can be reset using make sdk-config-clean
.
If custom settings are required for a project then place these in a separate file and set :envvar:`SDK_CUSTOM_CONFIG` to the location, relative to the project source root directory.
