OpenOCD Debug in Eclipse won't start

[bobbydigital]

There are no other messages that are added. The only thing I didn’t paste were the CDT Build console:

Well, as I can see you are running on a Mac. Once started the external tool, type this command on a terminal session:

$ telnet localhost 3333

And past here the output

[bobbydigital]

null-685b357e69f4:~ username$ telnet localhost 3333
localhost: nodename nor servname provided, or not known

tried this with sudo to and same thing.

thanks for the help, really appreciate it!

[Carmine Noviello]

Ok. That helps a lot. You have something wrong with the network settings.
From the terminal session run this command:

$ cat /etc/hosts

and past here the content.

[bobbydigital]

Huh. The directory exists, but the cat command returns nothing.

[bobbydigital]

GOT IT! Thank you!

This was the issue. I had nothing in /etc/hosts for whatever reason. I added this to the blank file:

##
# Host Database
#
# localhost is used to configure the loopback interface
# when the system is booting. Do not change this entry.
##
127.0.0.1 localhost
255.255.255.255 broadcasthost
::1 localhost

And I can enter debug mode. Thank you again very much for this! I really appreciate the help and patience!
