U-Boot Commands

U-Boot Commands

The topic describes the U-Boot command list and how to log in to the U-Boot command-line interface (CLI).

Logging In to the U-Boot


You can log in to the iBMC U-Boot over a serial port.

You can load underlying software and debug underlying devices on the U-Boot user interfaces (UIs). Contact maintenance engineer for the operation.


  • User name and password for logging in to the iBMC

    The default user is root, and the default password is on the product nameplate.

  • Password for logging in to the iBMC U-boot

    The default password is Huawei12#$.

To ensure system security, change the initial password after the first login, and then change your password periodically.


  1. Log in to the iBMC command-line interface (CLI) by using a serial port communication tool.
  2. Reboot the iBMC.

    iBMC:/->ipmcset –d reset
    This operation will reboot iBMC system. Continue? [Y/N]:

  3. Type Y and press Enter.

    The iBMC restarts.

  4. Press Ctrl+B when the message "Hit 'ctrl + b' to stop autoboot:" is displayed.

    The output is as follows:


  5. Enter the password for logging in to the U-Boot. The default password is Huawei12#$.
