Hello,
GPIO_LED[0] is a "heartbeat" LED, and is blinking as long Xillybus' IP core gets a clock (on some systems it won't blink if the core is held in reset).
GPIO_LED[3] reflects a certain internal state, but if it's always on, it probably indicates that the core is held reset. The plausible cause for this is that something is wrong with the PCIe link at the low level.
Regards,
Eli
