MCU? Any code can use any designed ram, you need handle bus capacity. Use linker section for this.

thanks for answer;i want to ask another question; Because the project is more complex, ui controls and containers are more, including text and dynamic text are many; HardFault_Handler freezes when adding text or ui images. The current test found that add a few dynamic text definition on crash, delete after normal; Also encountered after adding a picture crash, delete the picture after normal

If each screen shares a function or control, such as a hover button (used in both screen0 and screen1), the function of the hover button in screen0 must be the same as it is in screen1; Switching screens does not free up resources; What's the best way to share a function?
