    • 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

    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
    .itcm_ram 100 2118952

    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
