This commit adds support for dfu targets for cmake2. The following changes have been made: - Adds a new tools/cmakev2/dfu.cmake file on similar lines as the tools/cmake/dfu.cmake file. - Adds the idf_create_dfu() function to create the dfu targets. This function now takes the executable as an argument thus allowing the dfu target to be created per-executable. - idf_project_default() is updated to create the dfu target.

idf_create_dfu(<binary>
|
|
TARGET <target>)
|
|
|
|
*binary[in]*
|
|
|
|
Binary target for which to create DFU targets. The binary target is
|
|
created by :cmakev2:ref:`idf_build_binary`.
|
|
|
|
*TARGET[in]*
|
|
|
|
Name of the DFU generation target to be created (e.g., "dfu", "dfu-app").
|
|
Also creates "<target>-list" and "<target>-flash" targets.
|
|
|
|
Create DFU (Device Firmware Update) targets for the specified binary target.
|
|
DFU is only supported on certain targets. For other
|
|
targets, this function does nothing.
|
|
|
|
Note: DFU is not supported when secure boot is enabled. This function will
|
|
not create DFU targets if secure boot is enabled.
|
|
|
|
Three targets are created:
|
|
- <TARGET>: Generates the DFU binary file from flasher_args.json
|
|
- <TARGET>-list: Lists connected DFU devices
|
|
- <TARGET>-flash: Flashes the DFU binary to a connected device
|
|
|
|
Example usage for default project:
|
|
idf_build_binary(myapp TARGET myapp_binary OUTPUT_FILE myapp.bin)
|
|
idf_create_dfu(myapp_binary TARGET dfu)
|
|
