You don't have permission to upload you program
a) check that you can write to /tmp folder, if not you need can change 
destination folder in Download tab to one you can
b) actually permissions for /tmp is for user that started qconn on 
target, it is recommended to start it as root user.
c) if you have process running on target, for example /tmp/hello and you 
try to launch another one with the same name from IDE, this would fail 
too because binary cannot be written while program is running
