PA00 (pin13) can't be used as GPIO!!!

Hi there!

I've (another) weird issue, I can't use the GPIO27 (pin 13 / PA00) pin as GPIO...
in my fex file it's commented in any other possible usage (uart and jtag), thus the only one is in gpio_para


gpio_used      = 1
gpio_num         = 4
gpio_pin_1 = port:PL10<1><default><default><1>
gpio_pin_2 = port:PA15<1><default><default><0>
gpio_pin_3 = port:PA00<1><default><default><0>
gpio_pin_4 = port:PA03<1><default><default><0>


normal_led      = "gpio_pin_2"
standby_led   = "gpio_pin_1"


Listed is not available
ls /sys/class/gpio_sw/normal_ledPA15PA3PL10standby_led
Any advice?
Thanks!

Information is too little.
Please show me your hardware model and used OS image.

Sorry; hardware is based on 2x orange pi plus2, debian jessie minimal and fedora minimal (both from loboris) with the same problem other ports could be used as GPIO with no problems.
Thanks in advance
