SPI/GPIO support

gerfen · January 2020

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?

I have some more info. I can see that the drivers are installed when I run "devcon status acpi*" [1]

With the help of an AAEON engineer I was able to get the SPI functionality enabled on the UP Core. Here are the steps required:

Install the UP Core SDK

In the "IoT" folder, the RemoteInstallation.ps1 file needs to be modified with the correct user name and password.
After this is done the script can be executed from an Administrative Powershell session to install the SDK on the UP Core.

Then the attached ACPITABL.dat file needs to be copied to "C:\windows\system32" on the UP Core.
Reboot
Run "spitesttool -list" to confirm the UP Core has been properly configured.

Here's the mapping * between the UpBridge SDK and the physical pins on the UP Core...

please excuse the formatting it appears that the forum does not support Markdown tables. I've included an excel file with the same info.
