Task generators created from other task generators may be skipped during partial builds. This change re-enables install_task as a task attribute and provides a task object with input and output nodes which can be re-used by other tasks.

"""
|
|
Support for converting linked targets to ihex, srec or binary files using
|
|
objcopy. Use the 'objcopy' feature in conjuction with the 'cc' or 'cxx'
|
|
feature. The 'objcopy' feature uses the following attributes:
|
|
|
|
objcopy_bfdname Target object format name (eg. ihex, srec, binary).
|
|
Defaults to ihex.
|
|
objcopy_target File name used for objcopy output. This defaults to the
|
|
target name with objcopy_bfdname as extension.
|
|
objcopy_install_path Install path for objcopy_target file. Defaults to ${PREFIX}/fw.
|
|
objcopy_flags Additional flags passed to objcopy.
