I’m working on an embedded project for STM32 Bluepill. I was using Stm32CubeIDE for development but I recently transitioned to CLion (Jetbrains) as I really like that IDE. However, I noticed there’s a noticable size increase when building with CLion. My flash memory is almost at capacity at 63.8KB whereas when I build the same code in Stm32CubeIDE, the flash is only used up 48KB. The MCU has 64KB flash memory and I still need to add stuff so it seems if I continue using CLion, I’ll be running out of flash memory very soon.
