I'm not an IAR user, but it is likely complaining that it doesn't have an algorithm for programming an external memory (option for many different types of memory, with board unique wiring), only for the internal memory standard to all of the F7 parts,

The graphic image data will not fit within the internal memory, so the linker places it in an external region. The debugger doesn't support programming that memory and complains. You will need to create a .HEX file from the project, and then use the ST-LINK Utilities to program the board, you'll need to select the 'External Loader' supporting your board.
