Handling Process

At present, the SMM serial would be used if we want to recover the password of SMM forgotten. And the operation should be in the field. Here are the steps:
Notes: Make sure there is only one SMM board in the frame when we recover the password, because the recovery will synchronize in both master and backup board if there are two SMM boards in the frame.
1. Open super terminal, configure the baud with 115200 bps and make sure the connection with the SMM serial well.
2. Swap SMM board for resetting.
3. When it comes to “Hit 'ctrl + b' to stop autoboot: 0”, press “ctrl + b” to enter bootrom startup order of SMM board, enter password://set the password smmpass.
4. Input command “a” in the order to enter bootrom control table. If the version is different, the option may be different.
************************************************************************
'0' -----load kernel fpga rootfs from server and save them to flash, then boot
'1' -----load kernel and fpga from server and save them to flash, then boot
'2' -----load kernel and fpga from flash, then boot
'3' -----load kernel and fpga from server, but not save them to flash, then boot
'4' -----set  boot_params(server ip, board ip, kernel image,fpga image)
'5' -----show boot_params(server ip, board ip, kernel image,fpga image)
'6' -----load rootfs image
'7' -----restore the whole root file system and kernel and fpga
'8' -----load kernel fpga rootfs from server and save them to flash
'9' -----load uboot from server and save it to bootrom
'a' -----enter command console
'b' -----show this menu
************************************************************************
$>// Input command “a” in the order to enter bootrom control table
5. Input “pwdclr” in the control table.
$>a
=> pwdclr
6. The command will reset the Linux core. After the reset, we can log in the SMM board with user name only.
MontaVista(R) Linux(R) Professional Edition 4.0.1 (0502020)
SMM login: root
Password://no password
out of login ok
root@SMM:/#
7. We can modify the password when log in. For the old password is needed when we modify the password, so we use the command “passwd_bak” to reset the password first and then use command “smm_passwd root” to modify the password of the SMM board.
root@SMM:/#passwd_bak// reset the password for the login of the command line of SMM board
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@SMM:/#smm_passwd root// modify the password
Input old password:
New smm password:
Re-enter new smm password:
Changing password for root
Password changed.
Updating password for user root
8. Finish the password change and reboot the SMM board.
