Use the IAR ELF Tool to convert executable targets to their binary formats - IARSystems/cmake-tutorial GitHub Wiki

A CMake function can be used to convert executable target (*.elf or *.out) to binary formats such as Motorola S-Record (*.srec, *.mot), Intel Hexadecimal format (*.hex) and Raw Binary (*.bin).

• CMake projects using the IAR C/C++ Compilers with the IAR ILINK technology.

• $<TARGET_FILE:tgt>
• $<TARGET_PROPERTY:tgt,prop>
• add_custom_command()
• function()

• Add the following function() to the CMake project:

# Convert the ELF output to its binary formats
function(iar_elftool tgt)
  add_custom_command(TARGET ${tgt}
    POST_BUILD 
    COMMAND ${CMAKE_IAR_ELFTOOL} --silent --ihex $<TARGET_FILE:${tgt}> <TARGET_PROPERTY:${tgt},NAME>.hex
    COMMAND ${CMAKE_IAR_ELFTOOL} --silent --srec $<TARGET_FILE:${tgt}> <TARGET_PROPERTY:${tgt},NAME>.srec
    COMMAND ${CMAKE_IAR_ELFTOOL} --silent --bin  $<TARGET_FILE:${tgt}> <TARGET_PROPERTY:${tgt},NAME>.bin
)
endfunction()

• Call the iar_elftool(<target>) function replacing <target> by the actual executable target. Example:

iar_elftool(MyTarget)

• Build the target.

• Find MyTarget.hex, MyTarget.srec and MyTarget.bin inside the build sub-directory.

• Invoking IAR binary utilities
