I wonder which layer the bug is most possible and then focus on some modules.

I don't have efficient debug tools for some reason. what I can do now is inserting a piece of debug message in the spefic code . then dump the another board's hardware shared memory. Debuging the embedded real time system is very tough. If your debug task cause inappropriate workload, it may result in system status will be totally different.
That's a bug fix and custom won't be very patient.

Now I have mixed information.so I am confused.
telnet fine means problem should be upper than TCP
first channel fine, means application is good.
My code trace now is TCP task received bad message

As far as I know, students in Purdue did a big assignement like implementing an IP router. Reading only give us an overview. Engineering needs challengable projects and more hands-on experience.

Steven's looks like based on 4.2.1,isn't it?
