Linux would indeed not do anything. You may be using old GDB stubs in the
edb7xxx flash that may not support thread debugging unless you enable
"Include GDB stubs" in your downloaded application. You can either enable
that option in your configuration, or perhaps consider switching to RedBoot
- see http://sources.redhat.com/ecos/ and click on Supported Hardware, and
then the "More Info" link for your board. That will point you at RedBoot
binaries to program into Flash in the same way as the GDB stubs.

Yes.
