| 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. |
