How to Add EPCS_Controller in Custom Target Board?

[Altera_Forum]

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&#39;s Nios core. And, I cannot add EPCS_Controller. I don&#39;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.

But, you can not boot the program from serial flash by ASMI. 

EPCS controller support the boot_loader, but can not use it. It&#39;s so pity!  http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif
