Thanks. My mistake. For the record, it said GPIO_LED[2] before, and I just edited the post and fixed it.

GPIO_LED[2] or GPIO_LED[3] ???
as i know GPIO_LED[3] indicates core reset?

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

As it is connected to LEDs ..
GPIO_LED[0] == DS12 will be blinking alwz
GPIO_LED[3] == DS10 will be always on..

Is there any indication of this.....??
