nios2-terminal and jtag

Can't bind to port 1309 means that there is another instance of jtagd already running (you are only allowed one per machine)

The port permissions error means that you need to add udev rules to make usb-blaster nodes readable and writable by your user

In this case I think the real error is that jtagd can not find pgm_parts.txt, which it needs to find out the instruction register lengths and properties of the devices it's found on the jtag chain (I know this because the output of jtagconfig did not contain any names). What's the path reported by `ps aux | grep jtagd` after you run jtagconfig?
