Has anyone been able to do GPIO read or write without using the FriendlyArm library?
The library they have requires you to build your app as part of the system which makes debugging and testing virtually impossible.
I have a driver from the past but the directory structure for the GPIO is different. Under the /sys/class/gpio directory I can see gpiochip64 for GPIOC but I can't figure out how to use this as nothing appears if I LS it. cd into it and it seems to a link.
Any clues as to how to do it without a system build?
