Status LEDs are used for signaling system states. These LEDs are located on the XRF4-RFBB as shown in Figure 1. The following table summarizes the LEDs that are directly controlled by the XRF4 System Controller.
| Location | LED Name | Color | Description |
|---|---|---|---|
| LED1xp | XRF4 INIT | Green | Indicates PetaLinux successful boot. |
| LED2xp | XRF4 SLICE COM | Red | Indicates SOM communicates with slice over I2C/SPI. |
| LED1a, LED1b, LED1c, LED1d, LED1e, LED1f, LED1g, LED1h, LED1i | Slice power fault LED | Red | Indicates slice voltage/current is above the per slice programmed threshold. |
| LED2a, LED2b, LED2c, LED2d, LED2e, LED2f, LED2g, LED2h, LED2i | Slice detect LED | Green | Indicates successful slice detection. |
