Program size calculation using STM32CubeIDE

chai2145 · ‎2024-10-08

Hi,

When compiling program using Keil IDE, understand that the program size that flash to MCU can be calculate by:

Program size = Code + RO + RW

However, when compiling using STM32CubeIDE, how to know the program size going to flash into the MCU flash memory? I got the following memory details as below.

Is the program size = text + data?

Yes, for a standard program that's the amount that will be sent to flash.

As @Andrew Neil says, the Build Analyzer (Window -> Show View -> Build Analyzer) will show this and more detailed information.

The Build Analyzer tells you:

A complex system that works is invariably found to have evolved from a simple system that worked.
A complex system designed from scratch never works and cannot be patched up to make it work.
