OK, this was my fault... The problem is not here.

Does it support external break? 

For now, I tried with a minimal eCos program: no libc, no serial driver, no
gdb stub in HAL, no GDB external break support, no multithreading debug
etc.... But a very simple
"while(1) i=i+2;"
program

So I can connect to jeeni, i can load the program, If i set a breakpoint in
my main it stop correctly. But I can't interrupt it by hitting the Stop
sign. (Seems thats what Siegfried Schaefer talked about)

I suppose there is no way to have MultiThreading Debug Support via
Jeeni.(Unless maybe there is some support in eCos) . But external break
should be possible 

Thanks

A+
