Steps to Enable Networking on Orin

By default, switch firmware and switch tools are not part of the PDK. Follow the steps below to enable EQOS networking on the board.

  • Boot AV+L.

  • Reset the switch from Orin console:

    1. sudo su

    2. echo 454 > /sys/class/gpio/export

    3. echo out > /sys/class/gpio/PQ.06/direction

    4. echo 0 > /sys/class/gpio/PQ.06/value

    5. echo 1 > /sys/class/gpio/PQ.06/value

  • Bring EQOS interface up:
    sudo ifconfig eqos_0 <ip address> netmask 255.255.255.0 up
