RE: size of the executable using make command

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.

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
