$ nios2-flash-programmer --epcs --base=0x2000 --instance=1 FPGA.flash
Using cable "USB-Blaster ", device 1, instance 0x01
Resetting and pausing target processor: OK
No EPCS registers found: tried looking at addresses
     0x00002000, 0x00002100, 0x00002200, 0x00002300 and 0x00002400
Leaving target processor paused

and yes my epcs is at that address: 

#define EPCS_CONTROLLER_NAME "/dev/epcs_controller"# define EPCS_CONTROLLER_TYPE "altera_avalon_epcs_flash_controller"# define EPCS_CONTROLLER_BASE 0x00002000

any ideas? :)
