Led Control; Accessing The Boot Loader - Emerson PACSystems IPC 2010 Quick Start Manual

LED Control

If a user needs to control LED behavior directly, this can be achieved in
Linux using the pseudo-files located in
/sys/class/leds/

Accessing the Boot Loader

The boot loader of IPC 2010 is configured to start the installed Linux O/S
automatically without user interaction.
If it is necessary to access the boot loader settings or change the boot
process, a serial connection cable as described above is required to
access the U-boot console.
More information about the boot loader and its functionality can be found
in the document 'CPU1v2 U-boot Manual', which is available from
Emerson.
