Determine RAM usage with arm-gcc

[pbirkner]

Hi,

I have an application that utilizes the dual bank bootloader and s132 soft device on the nRF52832 chip. I am trying to determine the total RAM used and can't seem to find a simple solution. I am using arm-gcc to compile. Is there a simple way to determine this upon compilation? I've looked at the map file in my _build/ library, but I can't seem to make any sense of it. Thank you!

You can use the size utility for gcc.

$ size file.out

   text       data        bss        dec        hex    filename
 0x1408       0x18      0x81c       7228       1c3c    file.out

data + bss is stored in RAM
