SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

How to find the memory usage

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

Hi

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
