I haven't done it yet, but you're supposed to collect all 120 stars. After that, the Canon should be open. Also, you're talking about super mario 64 right, because that's the only "canon outside the castle" I know of. Anyway, there you go.
You open the cannon by getting 120 stars. After you've gotten 120 stars, you can go outside and fire the cannon. You do not need to find a Bob-omb buddy.
