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!

Is anybody using the XScale IQ80310? We are developing a product around the
XScale and would like to know how well ecos runs on the IQ80310 development
board before we begin. Any information would be most appreciated.
Thank you,

If you search the ecos-discuss list archives, it seems quite a few people
are using the xscale port. Give or take occasional bugs in anonymous CVS,
it should be pretty stable now.

Hard to say without seeing the code. But I probably wouldn't have time
to read it anyway.

How about running the serial tests that come with eCos? There's a
testing infrastructure that does what you try to do, and more. See the
io/serial/current/tests/README file - which is a bit out of date, but
should guide you in the right direction.
