Hi,

we have got a similar problem. We wanted to switch from NIOS IDE 8.1 to the "new" NIOS EDS 10.0.

Everything works fine, until we try to download our software to the board.

We get following error message:

--- Quote Start ---

Verifying 02000020 ( 0%)

Verifying 020070A4 (67%)

Verifying 02008EC8 (87%)

Verifying 03700000 (99%)

Verify failed between address 0x3700000 and 0x370001F

Leaving target processor paused

--- Quote End ---

At 0x03700000 - 0x0370001F the altera_avalon_cfi_flash is located. I assume it is the "reset"-region.

In our Design we have got SRAM and SDRAM. But obviously downloading to this regions works, because verifying pass.

I have to add that we compiled the Hardware-Design with Quartus 8.1 and used the *.sopcinfo file of that version.

I hope this isn't a problem.

@Chase: Which excact output do you get, when you try to download the software? Does the Verify fail? Which NIOS EDS Version are you using?

Regards

Phil
