How to save the screenshot of the LCD on the target board into SD?

[Xu]

I found the void HALSDL2::saveScreenshot(); function, but it is located in the path of the simulator. Can the target board use this function?

No, it can't.

You have to make something that can

1. Read from the framebuffer you want to dump (can be multiple) - We don't use that concept on the windows simulator
2. Write files and directories on whatever media you want (SD Card)
3. The simulator uses a method called SDL_SaveBMP()) which is a part of the SDL framework. You can probably get some inspiration from that.
