    BSEC2 binary size, Cortex-M0+

    Hi,

    I have a question  about binary size of BSEC2 library.

    The document "BSEC Binary Size information.pdf" shows that when Cortex-M0+ platform is used with arm-none-eabi-gcc compiler is needed only 34021 bytes (ROM), but when I compile my project the size is larger.

    IDE information: MCUXpresso IDE, compiler arm-none-eabi-gcc, language standard C99, library NewLibNano.

    MCU: MKE15Z, Cortex M0+

    Flash memory used without BSEC2 library:

    Flash memory used with BSEC2 library:

    As we can see library size is 57068 bytes in my project, it is larger than the 34021 bytes expected.

    Is there something I can do to replicate the expected size?

    Hi Irepan,

    You can add the option of optimizing the code in the compiler to reduce the size. such as -fdata-sections, -O2.
