Not able to debug treads using gdb 6.6 on ARM11 + linux 2.6.11 kernel

[pankaj chauhan]

Thanks for your response daniel. 

I don't see any process with pid 356 when i do 'ps -A',  but again if i try to attach to any other thread then it says again:

----
[New Thread 1024 (LWP 356)]
Can't attach LWP 356: Unknown error 3
----

and if i try to attach to 356 it says:
----
(gdb) attach 356
Attaching to process 356
ptrace: Unknown error 3.
----

It's the main thread of your process.  Try attaching to that instead.
