Verify Failed

Hmm I have similar problem here.

I was able to compile and run the 'custom instruction tutorial' with version 5.0 QuartusII and NiosII.

Now I removed them and install version 5.1 of QuartusII and NiosII.

With the same project, I am keep getting below message.

I am using UP3 Board with Cyclone device.

I didn't use SDRAM, I am using SRAM only.

Does anybody have idea?
