How to Dig into Firmware Code Size

hey there. I wanted to use puncover for a msp430 gcc toolchain. Is this specifically made for arm controllers? because i get the following error message:

raise Exception("Could not find %s" % path)

Exception: Could not find C:…\msp430-gcc-8.3.0.16_win32\bin/arm-none-eabi-objdump

this file is in my case named: msp430-elf-objdump
