[ECOS] ppc-gdb-ecos-reboot question

[Bob <bobvrpf at gmail dot com>]

Hi there!

I'm trying to setup a remote gdb environment on my ppc based board
through redboot. reboot was built by others. I cannot find the source
code and don't know if remote gdb ever worked on it before.
Luckily, the connection b/w gdb and the stub and loading debug file
can be successfully done.
Unfortunately, the program stops execution at some point after the
continue command is issued.
attached is the debug output, could you please give me some hints on
this issue or how to dig it deeper?

Thanks,

Bob
