    Nano product BSP Release Note - EN713

==========================================================


===================================
 Installation
===================================

1. Decompress by root
   sudo tar zxf EN713-R1.0.4.4.6.tar.gz

2. Enter L4T directory
   cd JetPack_4.6_Linux_JETSON_NANO_TARGETS/Linux_for_Tegra

3. Connect a Jetson platform and a host PC (Ubuntu 18.04) through a Micro USB to USB Cable

4. Enter the recovery mode
   power off -> press recovery button -> power on -> wait 2 seconds -> release recovery button

5. Start to flash BSP
   a. Use default user account.  ( user_name/password: nvidia )
      ./install.sh
   b. Create other user name and password as default user
      ./install.sh --create_default_account

6. Flash more modules (speed up)
   ./install.sh -r


===================================
 Test Commands
===================================

1.  Configure Ethernet interface to DHCP or static IP

   - PCB version E or later

      a. For Gbe port (eth0)
            # static ip
               sudo nmcli con delete eth0   # remove original setting
               sudo nmcli con add type vlan con-name eth0 ifname eth0 dev dummy1 id 2 ip4 192.168.0.100/24
            # DHCP
               sudo nmcli con delete eth0   # remove original setting
               sudo nmcli con add type vlan con-name eth0 ifname eth0 dev dummy1 id 2

      b. For 8 PoE ports (eth1)
            # static ip
               sudo nmcli con delete eth1   # remove original setting
               sudo nmcli con add type vlan con-name eth1 ifname eth1 dev dummy1 id 1 ip4 192.168.1.254/24
            # DHCP
               sudo nmcli con delete eth1   # remove original setting
               sudo nmcli con add type vlan con-name eth1 ifname eth1 dev dummy1 id 1

   - PCB version from A to D

      # static ip
            sudo nmcli con delete 'Wired connection 1'
            sudo nmcli con add type ethernet con-name 'Wired connection 1' ifname eth0 ip4 192.168.0.100/24

      # DHCP
            sudo nmcli con delete 'Wired connection 1'
            sudo nmcli con add type ethernet con-name 'Wired connection 1' ifname eth0

2. Sample commands to display PoE camera
   (Please make sure the IPs of interface and PoE cameras are in the same LAN.)

      # modify this url according to the camera
      url="rtsp://admin:admin@192.168.1.202/stream0"

      gst-launch-1.0 -e rtspsrc latency=300 name=src location="$url" ! rtph264depay ! h264parse ! omxh264dec ! queue ! nvvidconv ! video/x-raw,width=240,height=160 ! xvimagesink src. ! rtppcmudepay ! mulawdec ! alsasink

3. Control PoE power supply (PCB version E or later)

   When the system is shutting down, PoE power status can be changed in /etc/poe.conf file.

   For example:

      - Turn off power supply of all PoE ports
            sudo avt_tool -S "00000000"

      - Turn on power supply of all PoE ports
            sudo avt_tool -S "11111111"

      (Each character represents a port, from left to right.)
