Recently have been playing with uIP on the Olimex LPC1766 board. I have used uIP examples from the FreeRTOS 6.1.0 and from the NXP port if CMSIS (dated June 18 2010).
It seems that the FreeRTOS example (CORTEX_LPC1768_IAR) is sending all of its outgoing packets two times.
Also if you are planning to use uIP example from the NXP CMSIS and intend to access it from Windows XP or Windows 2003 machines then take look at this: http://support.microsoft.com/kb/815230
That can be the reason of 200ms delay at the PC between received TCP/IP packet and ACK response to it.
I have put more detailed description on my blog.
