| |
| 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. |
