In appnote AN3470 a couple of small applications are used on the PC to monitor TCP and UDP traffic sent from the coldfire. Additionally, the appnote mentions the freescale_UDP_client and freescale_TCP_client images to use for setting up the coldfire to send UDP and TCP data packets.
Is there a place where these two small apps and their respective Coldfire projects can be downloaded so that I can run some of my own performance tests?
