Total ROM and RAM usage

[sanju]

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.

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.
