size of the executable using make command

[raju]

I want to get size of the project executable and display it in make file. How to get exact size of the executable file in make file.

Can you please provide the make file command to extract this information.

Hi,

You can get the size by calling arm-none-eabi-size _build/outfile.out

It will give you something like this:

   text    data     bss     dec     hex filename
  37568     128    4112   41808    a350 _build/example.out

Flash size = text RAM = data+bss dec = RAM+Flash

Go to your makefile.common and add it somewhere, for instance in the .out->.hex conversion:

## Create binary .hex file from the .out file
$(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).hex: $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).out
	$(OBJCOPY) -O ihex $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).out $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).hex
	arm-none-eabi-size $(OUTPUT_BINARY_DIRECTORY)/$(OUTPUT_FILENAME).out

Note, if you check out my colleagues repo and use those makefiles, then it's taken care of for you: github.com/.../template

Best regards Håkon

Thank you very much for your input!!!

Hey Hakon, I think "Flash size = text; RAM = data + bss; dec = RAM+flash" would be easier to read. Right now it's a little hard to figure out how the line parses.
