Hello,

I'd like to connect to RedBoot via Telnet during target's running net
application.
I tried to run nc_test_slave program as application and connect to
RedBoot via Telnet from host's cygwin.
The result is below.
$ telnet 172.16.1.200 9000
Trying 172.16.1.200...
telnet: Unable to connect to remote host: Connection refused
<...snip>
Once your application is started, RedBoot is no longer available.
Why are you trying to do this?
I would like to load new application object to target using RedBoot via
Telnet from host PC during target's application running.
Is it impossible ?
It is not possible. As I said, once your application is running,
RedBoot is out of the picture.
I got an impression from Anthony J. Massa's book that if setted two
different IP addresses between RedBoot and application,I could connect
to RedBoot via Telnet during application running. Am I mistaken ?
That's a reference to the ability of RedBoot to provide GDB
services via the network. The rest of RedBoot's functionality
is no longer available, once your application starts.
