.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
