GPIO Pin Number for User LEDs on ZCU102

 Hi 

I am trying to hard-code the pin numbers for user LEDs available on ZCU102 board. how can i hard-code the pin number in my device drivers to on/off the LED. 

As the literature says that user LEDs are PL LEDs, and are routed throught EMIO pins. I am unable to resolve the pin-numbet to hard-code in my custom linux device drivers.

 

Thanks

Look for Table 3-33 in UG1188 for a listing of the pin numbers for the User GPIO LEDs on the ZCU102 board.

Thank you for your reply.

According the Table 3-33, UG1188 , User LED 0 is connected to following resurce. 

AG14 GPIO_LED_0 LVCMOS33 DS38.2

 

My question is when i enable the EMIO pin of ZynqMPSOC IP  in Vivado Design enviornment , EMIO [0:95] pin array is available . now which EMIO pin is connected to "AG 14 GPIO LED_0" DS38.2. 

AXI GPIO peripheral IP can't be connected to EMIO pin.
