Edit: But I did not run install_drivers.sh as root. But now I can't set a breakpoint. Error message the device would not support this, connection lost and debugger hangs.

I assume you re-ran the driver install script as root. Here are some general installation instructions for Debian which can be a handy reference: http://processors.wiki.ti.com/index.php/Linux_Host_Support_CCSv6#Debian_7.5_64bit
Are you now able to connect to target and load the code successfully? Is it only when setting breakpoints that you get an error? If you are still havign trouble please provide additional details as to the exact hardware you are using, and exactly when and what error messages you see.
