I'm converting the Nios UDPOffload example into 10.1. It has some custom SOPC components for packet handling. When i generate the Nios BSP the .c and .h files for the components appear under the project explorer. Problem is i get compile errors saying the functions in these files are defined. I've looked through the BSP editor and i can't see the custome components under the drivers section there. I can see altera cores and the tse_mac, but not the custom packet stuff. Is there something else i need to do to include these files correctly? update: I've actually had to make copies of the files in the Project itself (not the BSP) with all the .h and .c in there to stop the compiler errors. I'm obviously missing something.
