LED blinking for 'EP9307' Arm processor with Linux OS

Dear members,
I have a touch screen Keypad with 3 LED s with ARM EP9307 processor and Linux OS .I have to blink one of them for an application .The device file name what i see is "dev/led" .Also the current program has only functions to turn on/off an LED using the 'write' for the LED driver "dev/led". can anyone please tell me how to use the 'ioctl' or 'write' to blink any one of the LEDs .The 3 LEDS are connected to the 3 pins
EGPIO6/SDO2 ,EGPIO5/SDI1,EGPIO4/SDO1 respectively
