Gpio access in Arria10 hps kernel in yocto build



Following the below, I am able to build the dtb, linux image & root file system.

Now i built the gpio kernel module from the socedk. But when i try to insert by following it gives the error

oot@arria10:~# insmod gpio_interrupt.ko gpio_number=448
[ 138.180519] Invalid gpio_number specified

Could some one help me in pointing out where can i find the correct gpio number.

Best Regards,
