Andre,

Thanks. I tried it and it and it seems to work.

One problem is after I programmed the device thru the Jtag, I tried to verify the image using the EPCS (active serial) header as a check.

The verify failed. Should the images produced be identical, or are there some formatting differences?

Although this a definite improvement over the two-header programming method, it does still require two different files. If both the EPCS device and the system flash could be programmed with the Flash Programmer Utility in Eclipse, that would be easier still.

There is a NIOS document "EPCS device controller core", which says that the older ASMI module which I included in creating a Flash Programmer Project, should be replaced with the EPCS controller module. I am hoping this is the answer. So far the fitter complains about allocating space in the EPCS device, so I must have something set wrong.

I'll post if I get it to work.

Thanks again.
