    I did kernel update as described by Edwin
    l viewtopic.php?f=26&t=5652&start=30#p15463 l
    I have tried kernel 4.4.14-bone-rt-r11, tried 4.9.13-bone-rt-r4

    also tried 4.4.52-ti-rt-r91 ... ertCNelson

    Every time when I update to RT kernel I loose SSH access to BBB.
    In case of problem with SSH, BBB FAQ says:
    Delete the file called "dropbear_rsa_host_key" in the location of /etc/dropbear/.
    Then you need run the command '/etc/init.d/dropbear start'.

    After update to RT kernel directory /etc/dropbear/ does not exist and no command /etc/init.d/dropbear

    Any suggestions how to activate SSH?

    In Putty choose "Serial" instead of SSH, change COM1 to COM3, leave speed at 9600.
    Open connection and login as root. If invitation doesn't come left-click inside putty window on the cursor and wait 15-30sec.

    If doesn't work, connect monitor, keyboard, mouse to beaglebone and do steps below in terminal. Open terminal and login as root.

    First try to regenerate host keys:

    rm /etc/ssh/ssh_host_*
    dpkg-reconfigure openssh-server

    If doesn't help, delete keys,

    rm /etc/ssh/ssh_host_*

    Reinstall SSH server. Beaglebone has to see Internet, connect Ethernet cable.

    apt-get install openssh-server

    If doesn't work, regenerate keys again:

    rm /etc/ssh/ssh_host_*
    dpkg-reconfigure openssh-server

    In my case I have got SSH working. In your case please post the result in this thread. m
