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.
