am335x mc系統添加串口密碼和root密碼

                                                               
l0:0:wait:/etc/init.d/rc 0                                     
l1:1:wait:/etc/init.d/rc 1                                     
l2:2:wait:/etc/init.d/rc 2                                     
l3:3:wait:/etc/init.d/rc 3                                     
l4:4:wait:/etc/init.d/rc 4                                     
l5:5:wait:/etc/init.d/rc 5                                     
l6:6:wait:/etc/init.d/rc 6                                     
# Normally not reached, but fallthrough in case of emergency.
z6:6:respawn:/sbin/sulogin                            
#S:2345:respawn:/sbin/getty -I root 115200 ttyO0      
usr:2345:respawn:/bin/login -f root              

修改爲 （刪除 -f root）

 usr:2345:respawn:/bin/login   

# /sbin/getty invocations for the runlevels.          
#                                                     
# The "id" field MUST be the same as the last
# characters of the device (after "tty").    
#                                                            
# Format:                                                    
#  <id>:<runlevels>:<action>:<process>                       
#                                                            
                                                             
#1:2345:respawn:/sbin/getty 38400 tty1

 

 

使用 passwd 修改系統密碼，然後串口登陸就可以使用新密碼登陸了
