Subject: [ECOS] running application problem [IXDP425]
Hi,
I have configured (with ecosconfig tool) and build default kernel for
ixdp425 board.
I have also build application in examples directory (hello, twothreads
ecc.).
The build process work fine.
When i download and run any application (with gdb and/or load command from
RedBoot prompt) the application "not exit".
For the hello program, the output of redboot is following:

The redboot does not return the prompt and I must reset the bord!

I enable tracing, and the output is the following:

Using insight I see that the execution break in the exit (rc) function, in
the incokemain.cxx file line 123.
What is the problem?
