2.8. Looking into the Drive-On-Chip Output

Additionally, just after turning the board on, you can observe the output from the drive-on-chip application that runs in the Nios V/g processor.
  1. Connect a micro-USB cable to the integrated USB blaster II in the board.
  2. Run (source the Nios V command shell if required):
    >> juart-terminal
