This document contains different information about the port
of U-Boot for the OXC board designed by Lucent Technologies,
Inc.
1. Showing activity
U-Boot for the OXC board can show its current status using
the Active LED. This feature is configured by the following
options:
CONFIG_SHOW_ACTIVITY
When this option is on, the Active LED is blinking fast
when U-Boot runs in the idle loop (i.e. waits for user
commands from serial console) and blinking slow when it
downloads an image over network. When U-Boot loads an image
over serial line the Active LED does not blink and its state
is random (i.e. either constant on or constant off).
CONFIG_SHOW_BOOT_PROGRESS
When this option is on, U-Boot switches the Active LED
off before booting an image and switches it on if booting
failed due to some reasons.
