Altera_Forumthanks all .
i remove Schottky diodes near epcs and every thing is ok. i donot know why!!!!!!!:)- Altera_Forum
if you can check your image via jtag and it runs as expected, then the source should be epcs & fpga connetion related.
could you verify that the MSEL pins are setup for AS mode ? when powering up the system, do you see the fpga request at the epcs pins ? you should see the DCLK and other signals... if this happens, do you see changes at the output of your epcs device that it is responding ? - Altera_Forum
thanks for reply.
my quartus is version 8.0. and it's programming file for epcs16 is *.pof. regards - Altera_Forum
If your Quartus Version is 9.1 then this is the case, as this Quartus Version has a bug in generating the required files for programming EPCS devices. This bug will be fixed with the next service pack. (a patch is availabe via MySupport).
