22 years agoHow 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.gif2 Replies

I had the same question when we did our target board. But, in the end, it didn'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'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's so pity! http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif
