Hi all,

I am trying to build a ROM-based system.

I connect a rom(with firmware code) on iwb-side bus and put a sram on dwb-side bus.
Then I find out OpenRISC fetches .data section content by dwb I/F.
I realize I should copy .data section content from iwb-side rom to dwb-side ram.
But I can't get any appropriate instruction to achieve this.

Any suggestion about this?
Or should I change this architecture(ROM-based)?

Thanks.

Nick
