|  | of U-Boot for the OXC board designed by Lucent Technologies, |

|  |  | 
|  | 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. |
