Total ROM and RAM usage

sanju · ‎2022-12-05

Hi all,

i have tried same project in two different IDEs( Keil and STM32CUBEIDE). i am confuse that why they both are telling different usgae for RAM and ROM.

Keil map file says:

Total RO Size (Code + RO Data) 21156 ( 20.66kB)

Total RW Size (RW Data + ZI Data) 2360 ( 2.30kB)

Total ROM Size (Code + RO Data + RW Data) 21284 ( 20.79kB)

STM32 Cube IDE says:

why the difference is there between these IDEs. application code is same and HAL code is generated by STMCUBEMX for both IDEs.

Programming101:

Not all compiler and linker are equally performant in memory footprint.

Compiler options will also affect footprint results. It is called benchmarking the compiler toolchains.
