i think it is 2Mbyte 

 

but in system.h it is  

# define EPCS_CONTROLLER_NAME "/dev/epcs_controller"# define EPCS_CONTROLLER_TYPE "altera_avalon_epcs_flash_controller"# define EPCS_CONTROLLER_BASE 0x0d003800 

#define epcs_controller_span 2048 <<--- 2Kbyte????:confused:# define EPCS_CONTROLLER_IRQ 15# define EPCS_CONTROLLER_DATABITS 8 

 

this makes my hardware+program code to be exceed the memory limit /???

The EPCS is a serial (SPI) flash. As such, it cannot be treated like standard memory. The "span" you're seeing is for the epcs _controller_, not the EPCS _device_ :-)
