EPCS4: Compilation problem

[Altera_Forum]

hello Good people 

 I&#39;m trying to add a EPCS4 flash momery to my desing. I&#39;m not able to compile it: When compiling I get the following error msg:  Error: Can&#39;t place the following nodes  Error: Can&#39;t place node "NiosII:inst|epcs_controller:the_epcs_controller|tornado_epcs_controller_ato m:the_tornado_epcs_controller_atom|internal_data0out" of type ASMI Block Error: Can&#39;t fit design in device Error: Quartus II Fitter was unsuccessful. 3 errors, 38 warnings  Error: Processing ended: Sat Sep 30 14:40:01 2006  Error: Elapsed time: 00:00:11 Error: Quartus II Full Compilation was unsuccessful. 3 errors.   I&#39;m relatively new to Quartus II and SOPC builder and I can&#39;t figure out where the problem lies. My board is EP1C12 cyclone.  My desing is very simple. It only contains the following components: - Nios II/e CPU with on-chip memory - One timer - EPCS flash controller - Active Serial Memory Interface - 2 input pins : sys_clk and sys-rest_n assigned pins 29 and 62 respectively.  I don&#39;t know if I missed to add some important device, pin or interface to make it work.   I would be greatful if there is some1 out there willing to help http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/smile.gif .   Thanks in advanced.

Hi Pegazaus 

 I&#39;m not sure but for me it seems that active serial memory interface contradicts with epcs controller. Why do you need active serial interface? Do you know that you can read & write directly from epcs device through epcs controller? For more information see Nios II Software Developer&#8217;s Handbook alt_flash_open_dev().  Good luck!
