Cretainly not! The raw API is an event-based API: you call tcp_connect() and return instead of watiting. Either your connected-callback (on successful connect) or your err-callback will be called later. However, you should at least see a SYN packet going out when calling tcp_connect(). But as I mentioned before, the Stellaris port for lwIP I once had a look at was using lwIP in a strange way, so this *might* be a race condition of using lwIP from different interrupt-levels (or interrupt and main loop).
