Config Tina OS
We suggest beginners use armbian OS because there are many informations about it on internet, and for Tina OS suits those who are good at Linux.
The Tina OS configuration steps of Lichee MaixSense are similar to M2dock, so here will not retell its usages.

The first time to start this system we need to set password. If you didn't set the password at the first time, there is no way to login anymore, only reburn system you can get the chance to set the password again.
If the password you set at the first time is complex enough, the system wil not accept the password and you need reset your password.
New to Armbian? Documentation: https://docs.armbian.com Support: https://forum.armbian.com New root password: ********** Repeat password: **********
After setting the password, we need to choose our shell, normally we use bash.
Choose default system command shell: 1) bash 2) zsh Shell: BASH
Then it asked to add a new user to avoid us only using root username, which is a good way to help us not destroying the system. Set the username and password by yourself.
Creating a new user account. Press <Ctrl-C> to abort Please provide a username (eg. your forename): ll Create password: ********* Repeat password: *********
The new creater user is granted root permission by default, and we can use this identity to login this board and control this system.
We can use command
passwd to change the password or delete the password.
For example, we can use
passwd -d root to delete the root password which we create at the beginning. We also can use
passwd root to reset password of root.
The following log are examples about
root@maixsense:~# passwd -d root passwd: password expiry information changed. root@maixsense:~# passwd root New password: Retype new password: passwd: password updated successfully
Here are part of example:
