Subject: [ECOS] Serial Driver + Multithreading

Hi
My target board is AT91EB40 but the source code is not same as the Redhat
eCos because I have done some port before eCos support it.
I have wrote a testing program which have 2 threads, transmit and receive,
are used to test the full duplex of the target board. In pc side, I have a
serial testing program used to do the testing. I did the 3 testing,
1. only transmit to pc (in loop)
2. only receive from pc
3. transmit to (in loop) and receive from pc (hold on the enter key to send
a block of data)
In case 1 and 2, the serial driver can work fine but it can't work in case
3. The problem occured in case 3 was that it can work correctly within a
short time and then it can't do the transmit and receive. I use the Ctrl+C
to break the program, I always see it break in the idle_thread_main.
What is the possible problem that cause the program run into this function?
What is the best way to do the debugging?
Thanks!
