Trouble getting Minnowboard Max GPIO working

SYoun7 — Mon, 19 Oct 2015 23:00:56 GMT

I am having trouble getting off of square one with GPIO on Mnnowboard Max. Basically, I am trying to get Blinky app running. Its a reference project for Win 10 IOT Core and works fine on that platform. But I need to run something similar on Win 10 IOT Enterprise (or alternatively, on WIin 8.1 Embedded Industry).

Win10 Enterprise: GPIO is found in device manager and and I can build the app in Visual Studio 2015 community and it runs BUT if reports that there is "No GPIO controller found"

Win8 Embedded: I installed the Intel Embedded drivers per Minnowboard Max wiki. I cannot figure out how to get a Visual Studio reference that allows me to use the windows.devices.GPIO namespace.

Does anyone have experience to get me started? After this my next requirement will be SPI which I believe will need the same solution.

Hello sly110,

Thank you for contacting the Intel Embedded Community.

In order to better understand this situation, could you please confirm with the manufacturer of this board that the Operating Systems listed are supported?

Thanks in advance for your cooperation to find a solution to this situation.

Best Regards,

Carlos_A.

Hello sly110

For Windows 10 Enterprise, it might be possible that thet Minnowboard Max is used different GPIO drivers that the ones provided by Microsoft or by Intel, my recommendations for you

1) Contact minnowboard support to ask for their GPIO drivers (the same used by the IoT Core BSP)

2) Use a fresh Windows 10 Enterprise Install with the default GPIO drivers.

3) You might try using this application: https://downloadcenter.intel.com/download/24345/Intel-Driver-Update-Utility Download Intel Driver Update Utilityto download the latest Intel Drivers (requires Internet access), but as I said, it might not work since Minnowboard is a third party board and they might have modified their drivers.

For Windows 8 enterprises here are some documentation and samples for the Microsoft page:

However on this forum we don't specialize on code development, I would suggest you the following support channels that might be more useful (specially for Visual Studio related questions):

Carlos, pretty sure it is. The Minnowboard Max is atom bay trail. Microsoft supports it at least in Win10 Core. Intel has drivers for Win8.1 Industry.

Thank you Adolfo for the links. I will try a different forum as you suggest.
