嵌入式试验箱S3C2410的bootloader源代码

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.
