Q: Why do I get the message "Launch failed. Error starting gdbserver - see console
for details" with no other details on the console, when launching a debug session
with the Nios II ISS target?
A: If you are running an antivirus program with a firewall, it might be blocking the listening
tcp port opened by the nios2-iss executable. You must unblock the nios2-iss program to
enable it to operate through the firewall. Please consult the help section of your antivirus
program, for instructions on how to do this.
