I'm looking for a way to control the Ryzen v1000 GPIO pin via the Microsoft UWP functions. I tried to use Microsoft's gpiotesttool sample code to do that, but the GpioController.GetDefault() always returns null.
That means the GPIO controller does not exist, but I can find that the AMD GPIO controller is in device management. What needs to be set in the BIOS?
Has anyone tried to control v1000's GPIO pin on the Windows 10 IoT platform?
