I've build Redboot with networking enabled for the E7T.
Using Insight I can download, run and debug applications
through the serial port with no problems.
However, when I use the network port rather than the serial
port, things don't work as well. Insight connects to the target,
downloads the code and then starts to run it. The
cyg_user_start() function runs correctly, but when that exits
and the Cyg_Scheduler::start() function is called everything
locks up.
That's when interrupts get enabled, if that helps. What are you expecting
to see? Have you tried setting a breakpoint somewhere in a thread that's
being run? Do you definitely *have* threads linked into your downloaded
app? Are they cyg_thread_resume()'d?
