Mbed OS Development on MCU

Hi, I’m a beginner to the Mbed OS environment.
I want to know what’s different between using-mbedos and non-using-mbedos in the MCU.
Does it need other external RAM or Flash on MCU?
Or is it just enough to use mbed OS with internal flash?

Thank you so much!


Yes, you not need external RAM or Flash, the MbedOS will run from on-chip Flash and RAM.
Of course it need little bit more memory than pure HAL solution. More content = more memory.
