cannot create hex elf files with cmakelists - gcc

Question

I am trying to use cmakelists to create a hex and elf file for my blinkled project, using IAR files.
The compilation is without errors with cmake but I dont see the files in the build folder.
my goal is to create a hex and elf files for flashing pursoses later on.
Can someone please tell me what I should modify to solve this problem?
thanks a lot

Answer 1

I convert to .bin and .hex it with the following command:
add_custom_command(TARGET ${APPLICATION}
POST_BUILD
WORKING_DIRECTORY ${CMAKE_CURRENT_BINARY_DIR}
COMMAND ${OBJCOPY} ARGS -O binary ${APPLICATION} ${APPLICATION_BIN}
COMMAND ${OBJCOPY} ARGS -O ihex -R .eeprom -R .fuse -R .lock -R .signature ${APPLICATION} ${APPLICATION_HEX}
)
One notable difference is the ARGS as suggested here: https://stackoverflow.com/a/53573133
