Updating eMMC image

The procedure and latest production file is listed here. The process took around 40 minutes on my system.

Point to note: Power the Beaglebone Black from a 5V supply capable of at least 1A. Disconnect both USB and Ethernet cables before flashing the eMMC.

Once the updating process is complete, log into BBB through Terminal or Putty. I got this message:
aswin@aswin-Inspiron-1440:~$ ssh 192.168.7.2 -l root
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@    WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED!     @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY!
Someone could be eavesdropping on you right now (man-in-the-middle attack)!
It is also possible that a host key has just been changed.
The fingerprint for the RSA key sent by the remote host is
36:75:f5:00:89:3c:7c:98:dc:bd:9e:4a:e8:3d:48:13.
Please contact your system administrator.
Add correct host key in /home/aswin/.ssh/known_hosts to get rid of this message.
Offending RSA key in /home/aswin/.ssh/known_hosts:1
  remove with: ssh-keygen -f "/home/aswin/.ssh/known_hosts" -R 192.168.7.2
RSA host key for 192.168.7.2 has changed and you have requested strict checking.
Host key verification failed.
Solution:

Go to home directory in host computer and create a config file in the below path:
cd ~/.ssh/
nano config
Type the following:
Host 192.168.7.*
    UserKnownHostsFile /dev/null
    StrictHostKeyChecking no 
Save and exit (Ctrl+X, Y, <Enter>)

SSH into the device and login as root.
ssh 192.168.7.2 -l root
Verify the new installation
root@beaglebone:/sys/class/gpio# cat /etc/dogtag
