| 6 | |
| 7 | U-Boot for the OXC board can show its current status using |
| 8 | the Active LED. This feature is configured by the following |
| 9 | options: |
| 10 | |
| 11 | CONFIG_SHOW_ACTIVITY |
| 12 | |
| 13 | When this option is on, the Active LED is blinking fast |
| 14 | when U-Boot runs in the idle loop (i.e. waits for user |
| 15 | commands from serial console) and blinking slow when it |
| 16 | downloads an image over network. When U-Boot loads an image |
| 17 | over serial line the Active LED does not blink and its state |
| 18 | is random (i.e. either constant on or constant off). |
| 19 | |
| 20 | CONFIG_SHOW_BOOT_PROGRESS |
| 21 | |
| 22 | When this option is on, U-Boot switches the Active LED |
| 23 | off before booting an image and switches it on if booting |
| 24 | failed due to some reasons. |
