Hi:

 Is there any way to put a binary file (for example, a bitmap file) into a specific address so the project can read it from flash? Is there any example show how to do it?

There are lots of ways to do such things. Do you have any experience with C and File IO (fopen/fclose/fread/fwrite/fseek etc)?

Using existing tools, probably you'd want to use things like BMPCVT, etc to convert binary data into a C data array which you can then include in your compile. For specific address placement you likely have #pragma or attribute directives either to specify addresses, or sections, to place the data. The secondary route would be via a linker script or scatter file to direct the output of specific sections or object files to memory.

Just taking straight binary you can specify addresses with ST-LINK or DFU Manager and manage placement that way.

If you have custom requirements you might want to consider processing the data components yourself with a script and packaging application. For file system type constructs, looks at MAKEFSDATA, part of LwIP as I recall. For hex data output SRECORDS
