RE: [ECOS] question about using gdb and reboot loading an application

[Ecos Temp <ecos1 at sorensontech dot com>]

Yep, I've be asking them, but it is hard talking to yourself and it is
freaking out people around my cube!

Anyway, some other clues:
- in gdb, when the continue command is issues, the downloaded image is not
executed.  I'm using a ICE to help debug this problem.

I'm now looking into generic_stub and start tracing using the ICE to see
what the issue is, any clues?

Nothing I can see. Where did you set the breakpoints? Anywhere early in the
startup? e.g. cyg_hal_invoke_constructors?

If someone else did this port (who?) ask them! It certainly wasn't Red Hat.
