SOPC Builder and nios ii help

Hi,

Those *_BASE constants are names derived from your SOPC project created in SOPC builder and are define in the system.h include file that gets created in the NIOS library directory for the project. Find the system.h file and see what they've actually been called. It could be that you inadvertently renamed the blocks in your SOPC design.

For example, your errors tell me that it's expecting you to have a SOPC block called DATA_IN, one called DATA_TYPE, etc. but maybe you named them MY_DATA_IN. Just change the references in the C code (toplevel.c) to match what the SOPC blocks are actually called.

Mark.
