BusTools
Microsoft is offering open-source samples for using hardware interfaces in Windows. A compiled version of these samples can be downloaded here:
...
Navigate to the directory containing the MinComm.exe in the command prompt and execute the file.
If you have connected your baseboard to your computer via the RS232 interface you will be able to transfer symbols by pressing keys on your keyboard between the two devices.
PWM
On Trizeps8Mini PWM4 is the only PWM that is configured by default. The Pin used for PWM4 is GPIO5_IO2 (SAI3_MCLK_PWM4_OUT). It is connected to SODIMM Pin 69.
On the pConXS III the signal is available on Pin 9 of the extension header.
PwmTestTool.exe can be used to activate the PWM.PwmTestTool.exe -list will show you a list of available PWMs. The first list item should be \\?\ACPI#NXP010E#4#{60824b4c-eed1-4c9c-b49c-1b961461a819} which is the PWM4.
Execute PwmTestTool.exe \\?\ACPI#NXP010E#4#{60824b4c-eed1-4c9c-b49c-1b961461a819} to access the PWM.
The commands open 0, start and dutycycle 25 will activate the PWM with a dutycycle of 25%.
Use the command help for more options.

PCIe
There is two ways to use the i.MX8M Minis PCIe interface on Trizeps8Mini:
...
Manual driver installation is very likely to be required to actually use the PCIe device.
...
CAN (only Trizeps VIII Plus)
The CAN interface of the i.MX8M Plus processor of the Trizeps8Plus can be tested with the “FlexCAN-interrupt” utility that comes with the BSP from NXP.
To test the CAN interfaces on a pConXS III simply connect two i-MOD CAN boards to the CAN interface of the pConXS III as described in the i-MOD CAN datasheet: i-MOD CAN - i-MOD standard
Connect the two CAN Interfaces with a male-to-male DB9 cable.
Use NXP’s FlexCAN_interrupt.exe (You can download it here:
