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