Recipes for extraction of executable files and other binary data
An arbitrary number of extra steps can be performed by the IDE at the end of objects linking. These steps can be used to extract binary data used for upload and they are defined by a set of recipes with the following format:

Code

recipe.objcopy.FILE_EXTENSION_1.pattern=[.....]
recipe.objcopy.FILE_EXTENSION_2.pattern=[.....]
[.....] 

FILE_EXTENSION_x must be replaced with the extension of the extracted file, for example the AVR platform needs two files a .hex and a .eep, so we made two recipes like:

Code

recipe.objcopy.eep.pattern=[.....]
recipe.objcopy.hex.pattern=[.....] 

Code

## Create output (dfu file)
recipe.objcopy.dfu.pattern="{compiler.path}{compiler.elf2hex.cmd}" {compiler.elf2hex.bin.flags} {compiler.elf2hex.extra_flags} "{build.path}/{build.project_name}.elf" "{build.path}/{build.project_name}.dfu"

## Create output (iap file)
recipe.objcopy.iap.pattern="{compiler.path}{compiler.elf2hex.cmd}" {compiler.elf2hex.bin.flags} {compiler.elf2hex.extra_flags} -R .boot "{build.path}/{build.project_name}.elf" "{build.path}/{build.project_name}.iap"
