Errors while running Nios configurations

Hello,

I am a beginner in designing NIOS system and I have designed a system based on the "Video and Image Processing Example Design (AN-427)" and adapted it to the development board I am using (DE2-115).

In Quartus II (64-bit version 10.1, service pack 1), using the SOPC builder I made a nios system with on-chip memory, jtag UART, system ID peripheral, video and image processing modules and SDRAM Controller (I also used an external PLL with a phase-shift of -3ns).

The generation of this system is successfull and the compilation in Quartus too. (But I have some critical warnings about "timing requirements not met"!)

After, using NIOS II 10.1 SBT, I built the C code for the nios which is successful.

Then when I am running the configuration to the processor on my DE2-115 board, I got many errors and I have no idea how to solve them.

Here is the list of those:

SOPC design not set.

CPU module not set.

The SOPC design does not contain a CPU of a supported architecture.

CPU architecture type not set.

And this end by the following error:

"Verify failed between address 0x30000 and 0x33117".

(the on-chip memory address is from 0x20000 to 0x3387f).

I don't understand if the critical warning I have in Quartus is related to the failure in Nios II. As I understand reading similar topic in the forum, "Downloading ELF Process failed" is related to bad timing in the design.

If this is the case, I do not understand how to solve those timing problem and need some help with that.

Also the NIOS II errors I have about the SOPC and CPU not set are strange as I am using the same method as before and I already succeed in make NIOS program work.

Does somebody know how I could solve those problems?

Thanks, Meach.
