I successfuly configured Http_Demop and Telnet demo to work Over PPP using Keil RL_ARM 3.10. But i am unable to do so with tftp demo. I have a LPC2148 based Evaluation Board with no ETHERNET. can somebody help me!!!
The problem with TFTP demo is that i am unable to connect to my evaluation board windows dial-up. The same is possible with HTTP demo and Telnet demo. Please help...
Following is the dump of my debug file. As soon as i type
c:\windows>tftp -i 192.168.125.1 PUT a.txt a2.txt
i get the udp error which is shown in the dump file.

Note that the errors actually start several lines before your highlighting!
It looks like you're initially allocating the UDP Socket OK at the beginning, but then failing to re-use it for subsequent packets.
So perhaps you should be looking at the code that decides whether a Socket is available...
Thanks.
I checked my code. It is the example code which was originally written for Keil MCB2300 board with ethernet connectivity. I modified it to use PPP instead of Ethernet. There is no code i found which is using UDP packets directly. Tftp might be using them internally. So unable to modify the code. You can download the code for MCB2300 and My modified code from the following link. Please help.

Have you tried just searching for the text string, "No Socket for received UDP frame" in the source?
Yes... found Nothing... I think it is a library message.... Here is the List of Which is included in the Project. (you can check the projects also.)
