Unable to synchronize with target

Hello everyone, 

My software is Quartus 4.2 and NiosII 1.1 

 

I used the procedure described in the doc to build a program, debug it and download it to the demo board. With no problems (apparently) 

 

Then i create my target board (with a cylcone EPIC20F400C7, 1 EPCS4, 2 SRAM IDT71V416S, 1 Flash AM29LV065D). With SOPC i generate the Nios component, then i compiled it with quartus, then i downloaded the code with the NIOS IDE (Using debug function). EVERYTHING seems to work OK (I mean, the LCD works, the serial ports works, all the signals I expect to be present, are present. 

 

The problem is when i try to use the Flash programmer with my target. Infact I got a message error 

 

"Unable to synchronize with target. 

"make: *** [epcs_controller_boot_rom_programflash] Error 6 

 

I checked for some problems on my target, but to me it seems to be all OK. 

 

I looked in this forum if someother had the same problem, and i read to check the memory (with memtest). I did it but the problem is still present. 

 

Thanks in advance to anyone that can give me some suggestion.
