What happens when you try that?

I expect you need the Large Code and Data Models. I don't use IAR, so I don't know what menu you would use to set this.

You should define it like this and change the data mode to large just like Bruce said

#pragma location = 0x10000
__no_init unsigned char Picture[40960];

For more information you can refer to the IAR C/C++ Compiler User Guide.

Best regards

Gary
