    Hi,

    Please check your devpath. You can use "dmesg" or "udevadm monitor" command to get more information.

    Hey! I need to be root to restart "tcpip" (adb tcpip 5555) from my application. How can i do this?

    I am using tinkerboard R as a kiosk terminal and I need to control it over a TCP connection after a system reboot (after reboot "tcpip" is off).

    Hi gc986,

    If you want do the following command on boot.

    Quote

    su
    setprop service.adb.tcp.port 5555
    stop adbd
    start adbd

    You can modify init.usb.configfs.rc by "remount"

    Quote

    adb root
    adb shell remount
    adb pull /init.usb.configfs.rc

    Add "setprop service.adb.tcp.port 5555" before "start adbd"

    adb push init.usb.configfs.rc /init.usb.configfs.rc

    Then reboot to check property has been set.
