Hi,all
Now I can run redboot on my board,and I can connect redboot through insight
5.0 under x window,using remote tcp target,then load my applications,run my
applications well, but I meet another problem--I can not break(use ^c) my
application when it is running,and when the application is over,I can not
close the gdb window either,and gdb can not connect redboot afterward,until
I kill the gdb,and run gdb again,is that the way redboot works? If so ,it is
too unconvenient,isn't it?Are you going to add ^c function to new redboot
version? When will it release? If I want to do it myself,will you please
give me a tip?

I know from the document that the redboot is thread aware,what is the
meaning? Because when I use "info thread" in gdb ,it always report "can not
get remote thread list",is anything I do wrong?how can I get thread info?

Any help will be highly appreciated!
