Tool for printing FLASH and RAM usage of firmware for avr and stm32

Prettier firmware size printer

Print size of used FLASH and RAM storage of avr and stm firmware by elf file. Allow to print used percents, and RAM usage of stack with help of ezstack.

Usage

--size=<path to toolchain size tool>
--elf=<path to elf file>
--ezstack=<path to stack analyzer ezstack> *optional
--mcu=<name of mcu, supported all avr mcu and stm32...>
--maxflash=<maximum size of flash. Needs for stm32 mcu. If specified prints used percents> *optional
--maxram=<maximum size of ram. Needs for stm32 mcu. If specified prints used percents> *optional

Example

python size_printer.py --size=path/to/avr-size.exe --elf=path/to/firmware.elf --ezstack=path/to/ezstack.exe --mcu="atmega168p"

Result

Device: atmega168p. Program data: 224 bytes (4.0%). RAM usage: 214 bytes (20.9%).

From CMake

set (PATH_TO_UTILITY size_printer.py)
set (PATH_TO_EZSTACK ezstack.exe)
add_custom_command(
	TARGET ${EXECUTABLE_NAME} POST_BUILD
	COMMAND
		${PYTHON_EXECUTABLE} ${PATH_TO_UTILITY}
		--size=${CMAKE_SIZE}
		--elf=${OUTPUT_DIR}/${elf_file}
		--ezstack=${PATH_TO_EZSTACK}
		--mcu=${MCU}
		)
)

Tests

Before run tests, set ENVIRONMENT VARIABLES (by .env file for example):

PATH_TO_AVR_SIZE_TOOL = <avr-size.exe>
PATH_TO_STM32_SIZE_TOOL = <arm-none-eabi-size.exe>
PATH_TO_EZSTACK = <ezstack.exe>
