EPCS4: Compilation problem

hello Good people

I'm trying to add a EPCS4 flash momery to my desing. I'm not able to compile it:

When compiling I get the following error msg:

Error: Can't place the following nodes

Error: Can'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'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'm relatively new to Quartus II and SOPC builder and I can'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'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!
