Hi, all



I have serious & urgent problem with RTCS UDP.


My environment is here.

        MCF52259 / CodeWarrior 7.1.2 / MQX 3.4


The problem is that UDP Overrun Error.


Firstly, I found this problem from longer than 900 bytes UDP packets.

However, this problem occurs very frequently at less than short UDP packets.


I've searched on Freescale Web site and found so many articles about FEC OVERRUN error.

It also releated to packet losting problem.


In my case, Why short packet is received successfully? and long packet is always discarded by driver?


So, could you test for me that your software can receive 1000 ~ 1500 bytes UDP packet?

Actually, I'm almost dying because this problem...


Finally, I'm planning to move on MQX 3.5.

Is it valuable try?



Thank you very much for reading my article.

Please give your any kind of suggestion....
