system ID not found at target base address

You need to either:

1) add a system ID component to your SOPC system

2) disable the system ID check (check both boxes in the "System ID Checks" area shown in your second screen shot)

I have a similar problem in my nios system. Before adding a new component

to SOPC builder nios ii work without any errors, but after adding my new component (programmed in vhdl) it gives me an error "system id mismatch" and is not connected.

I tried to connect it through refreshing the connection, but still have the same error.

Your help to fix this error would be very much appreciated.

Thanx in advance...

Hello,

I got exactly the same problems:

The system works well with one custom SOPC module added to the system, but with an other one the system ID and time stamp cannot be read from the board (DE2-115 or DE3 => it's not caused by the board but by the software/HDL-design).

The custom SOPC module of course compiles correctly. But it is very large in size (2.500 lines of verilog code).

Is there maybe a practical limitation of logic size due to delay times? (I don't really belief that...)

And why does the nios processor not respond anymore, even if the module isn't working correctly?

=> How can a faulty memory mapped slave module affect the processor? The mm-interface itself cannot be wrong because it is simulated, recognised correctly by the SOPC builder and used by me in some other working designs "copy-and-paste".

Maybe someone can give me a hint where to search further?

Thanks a lot in advance...

Hi friends,

I have the same problem here, I also did check the boxes for ignore ID check, and ignore the timestamp check, but it didn't work for me. Please help me out.

Thanks a lot.
