    • .rodata' will not fit in region `ROM'

    Posted by edge0xc on 2016-02-13 12:24

    Hey,
    i am playing arround with a stm32f303CBT6. Yesterday i tried to use the arm_math lib with sin and cos functions. but when i use them, i get the following error:

    STM32f303CBT6_MC.elf section `.rodata' will not fit in region `ROM'
    region `ROM' overflowed by 118192 bytes

    is the library that big, that i cant put it on the micro?

    Cheers,

    Alex

    Hi, I do not know about arm_math lib, but what I now if you want to use the very optimize c lib for arm gcc you can add this linker flag to link against it

    -specs=nano.specs

    It will reduce the size of the code size, which will reduce the .rodata

    best regards
