Jump to: navigation, search

By default, the serial console provides access to

  • kernel console
  • bootloader command line interface

Kernel console

The kernel console with full root access, provides the most powerful access gate to the Utilite device.

Bootloader command line interface

Prior to kernel boot, the serial console provides the U-Boot bootloader command line interface, which enables modification of kernel boot arguments.
Upon power on, U-Boot performs a short countdown (default 3 seconds), prior to proceeding to kernel boot.
Press ENTER to stop the countdown, and access the command line interface. Type in boot to proceed to kernel boot.

Connecting to serial console

The serial console is routed to (P9) RS232 jack on the left of the front of the device.
The line speed is pre-set to 115200 bps.
