The question about Configuration device.

The Altera NiosII Dev.Board uses the EPM7128 as the configuration download device, but Microtronix Cyclone Dev.Board has not. So I want to know how the NiosII runs the code stored in the flash on Mic...

Hello,

The first question I mean that EPM7128 is used as flash code download device(just store OS or App code in flash), not used as the configuration of FPGA(don't store .pof file).

Second,

You say "In my design the Reset Address is pointing to “ext_flash†and Exception Address is pointing to “sdramâ€. The base of ext_flash is 0x0 and is locked. Did you locked the base address?"

Yes, I did. But the same. So I think it maybe the wrong of the component(microtronix cyclone dev board flash). I have a test and change the Mtx gived flash component to Flash Memory(Common flash Interface) of the Altera SOPC Build provided. I set Address Width and Data Width(but I don&#39;t know how to set the Timing). This time no warning occurs. Why? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/sad.gif

This do not appear in SOPC Builder 2.7, but occurs in SOPC Builder 4.1.

Thank you.
