I'm trying to test out SPI connectivity on my UP Core on Windows 10 IoT Core. The UP Core is connected to a custom carrier board which has a SPI GPIO Extender. When I run the "spitesttool -list" I get the following message: "There are no SPI controllers on this system." When I run "GpioTestTool - list" I get this error: ' GPIO is not available on this system'. I see the same behavior when the UP Core is paired with the high speed and low speed UP Core carrier boards.
I have tried installing the UP SDK and see the same behavior. What do I need to do to enable SPI/GPIO ? Is there a BIOS setting?
