How to find the memory usage

Posted by beandigital on 2017-06-14 17:16

I am using the STM32F072 part with system workbench. How do I find out how much of the flash and RAM the program has used?

Thanks

Jon

You can set the post-build call to output that information to the console in a more readable format.

Project Settings -> C/C++ Build -> Settings -> Build Steps tab, look for the post-build steps command. There is already a call to arm-none-eabi-size at the end, if you insert --format=sysv afterwards you should get a nicer printout.

My total command looks like: arm-none-eabi-objcopy -O binary “${BuildArtifactFileBaseName}.elf” “${BuildArtifactFileBaseName}.bin” && arm-none-eabi-size --format=sysv “${BuildArtifactFileName}”

When the code builds, I get output on the console that has a table with the size in bytes of each section:

section size addr
.isr_vector 456 2097152
.text 21336 2097616

As above but with

 --format=berkeley

instead of

 --format=sysv

will give you output that may be more what you had in mind. For example:


arm-none-eabi-size --format=berkeley   src/*.o libraries/common/*.o 

   text	   data	    bss	    dec	    hex	filename
   1503	      0	      0	   1503	    5df	src/main.o
    339	      0	      0	    339	    153	libraries/common/assert.o
     84	      0	      0	     84	     54	libraries/common/compensator.o
    516	      4	     64	    584	    248	libraries/common/edgetracker.o
    328	      0	      0	    328	    148	libraries/common/ffcompensator.o
    696	      0	      0	    696	    2b8	libraries/common/leadcompensator.o
    682	  49161	    168	  50011	   c35b	libraries/common/logger.o
