Hi there! Can I use STM32CubeIDE to get hardware initialization code for using it in IAR IDE or it's possible only by STM32CubeMX?

Beyond the startup.s code most platforms build with exactly the same code.

IAR has some "In Ram" type directives, but these are used in some very limited circumstances.

The SystemClock_Config() is portable.

I mean can STM32CubeIDE generate IAR .eww files like STM32CubeMX does?

Sounds not. Do you know some IDE able to generate another IDE proprietary file(s) ?

Sounds only MX is able to.

Thank you for your answer. No, I really do not know such IDE. But in STMCubeIDE description page there is a statement :"STM32CubeIDE integrates all STM32CubeMX functionalities".
