How to Add EPCS_Controller in Custom Target Board?

I follow the instruction in "Nios II Flash Programmer's Guide" to make a Custom Target Board.

But I find that, i can only use ASMI(Active Serial Mem. Interface) in this target board's Nios core. And, I cannot add

EPCS_Controller.

I don't know why the "mk_target_board" instruction use the old ASMI instead the new EPCS.

How can I use EPCS_Controller in my board? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

    I had the same question when we did our target board. But, in the end, it didn&#39;t matter. The target board is only used for programming the flash and EPCS devices. I think that the code that Altera sticks in the on-chip RAM uses the ASMI device and not the EPCS controller. So, in answer to your question, you don&#39;t need to use the EPCS controller in your board.
