Connection to Nvidia Jetson

There are three ways how to connect to Nvidia Jetson from host computer: micro-usb cable connection through SSH, micro-usb cable connection through serial terminal (putty), wireless connection through SSH.

Micro-usb connection through SSH

  • connect usb cable from host computer to micro-usb port on DroneCore.Pilot marked as USB_DEV.
  • power on board and wait till jetson boots
  • open terminal on Linux host computer
  • type ssh [email protected] (dcs_user is default username)

  • enter password (default password = dronecore)

  • now user is remotely connected to jetson terminal

 

WIFI connection through SSH

  • WIFI card with antennas must be assembled on the board. (M2 WIFI cards verified: Intel AC-9260NGW, Intel AC-8265NGW)
  • power on board and wait till jetson boots
  • jetson automatically creates WIFI hotspot with SSID: DCS_wifi, PASSWORD: dronecore
  • find this WIFI network and connect to it from Linux host PC

  • open terminal on host PC and type ssh [email protected] (dcs_user is default username)
  • enter password (default password = dronecore)

  • now user is remotely connected to jetson terminal
  • NOTE: if jetson is not in access-point mode but connected to existing wifi network, user must know IP address of jetson in that network and connect to this IP ssh [email protected]

 

Micro-usb connection through serial console

  • connect usb cable from host computer to micro-usb port on DroneCore.Pilot marked as USB_DEV.
  • power on board and wait till jetson boots
  • open serial terminal program (putty, teraterm, gtkterm etc.) on Linux or Windows host PC
  • open corresponding port (jetson is commonly identified as ttyACM0 on Ubuntu host PC)

  • enter user name of user (DCS_user is default username)
  • enter password (default password = dronecore)

  • now user is remotely connected to jetson terminal

 

Some useful hints:

  • Changing ubuntu hostname:

    • execute following commands in terminal

    • hostnamectl set-hostname desired_hostname

    • sudo reboot

  • Changing ubuntu user-name:

    • execute following commands in terminal

    • sudo usermod -l desired_username current_username

    • sudo usermod -d /home/desired_username -m desired_username

  • Changing ubuntu user-password:

    • execute following commands in terminal

    • For user password: passwd

    • For root password: sudo passwd

  • Changing WIFI SID/PASSWORD:

    • execute following commands in terminal //add how to change automatic wifi hotspot sid/pass
