I'm migrating a working design from Altera DE2 to Altera DE2-115 and I'm running into problems. First everything works with DE2 just like mentioned in the exercises doing what is instructed. Now I want the designs to work also with DE2-115. So I make new designs with the chip that is for the DE2-115 (Cyclone IVE EP4CE115F29C7). But besides changing the chip to Cyclone IVE EP4CE115F29C7, I don't know what other changes to make. So I download the design (the mux4to1 mentioned in the text) to the board and it's not working. I didn't run a simulation with this project but it compiles and it's basically a copy in Quartus II of another project that was for DE2 and I just did a new project for the Cyclone IV chip and copied over the sketch. Now I wonder what I'm doing wrong since the design downloads fine in Quartus Programmer downloading to the board but the it doesn't run like it's suppossed to, the board is simply "locked". Do you have any ideas what I should do? I can provide more details if needed and I asked about this before and then the answer says that the "pin mappings differ" between DE2 and DE2-115.
So can you tell me where I can find what the pin mappings are and what I should change them to?
