Question / Issue:
When I try to ssh as root, I get the following:
$ ssh root@192.168.1.199
Permission denied, please try again
I'm sure I know the password.

Since ssh is answering, you know it's running. In our example below, we're using an NXP LS1046A-FRWY board running the Ubuntu userspace:
Via your terminal / UART, do the following:
# ps -e | grep sshd
6093 ? 00:00:00 sshd
# kill -9 6093
In the same terminal, edit /etc/ssh/sshd_config and remove the '#' in front of
PermitRootLogin yes
Save your changes and restart the sshd daemon:
/etc/init.d/ssh start
Starting ssh (via systemctl): ssh.service.
Now give it another try from your remote machine.
$ ssh root@<host ip address>
root@<host ip address>'s password:
