To test the USB communication in the Reference Architecture case is necessary:

• to download the correct reference bitstream file in the FPGA and/or SPI Flash;
• the USB FX2 microcontroller on the TE USB FX2 module should contain valid firmware;
• the host computer should have a specific driver installed;
• a USB cable should be used to connect the PC and the FPGA module (USB communication tests and/or power supply);
• run the C# or C++ Reference Project test (link to add ???).

Full test

...

To completely test the Reference Architecture is necessary:

• to download the bitstream file (that create the Microblaze system) and the demo.elf file or to be certain that this two are already downloaded before;
• the USB FX2 microcontroller on the TE USB FX2 module should contain valid firmware;
• the host computer should have a specific driver installed;
• the host computer should have Xilinx EDK installed;
• a JTAG adapter cable. We recommend using the Xilinx Platform Cable USB (USB ↔ JTAG) ;
• a USB cable should be used to connect the PC and the FPGA module (USB communication tests and/or power supply);
• run the C# or C++ Reference Project test (link to add ???) (USB communication tests + DMA tests). 

The procedures are the following.

Run the demo project

.bit or .mcs direct download iMPACT, OpenFut or OpenFutNet	Procedure SDK: opening and update SDK project only ('updated' SW on 'NOT updated' HW) Compile and link time less than 1 minute.	Procedure XPS+SDK: opening and update both XPS and SDK projects ('updated' SW on 'updated' HW') Resynthesis of reference HW could take from 10 minutes to 1 hour(1)
	Copy IP Cores and drivers used in TE reference projects
		Update XPS project from an old version to a new one
		Export the HW design to SDK
	Open SDK project and (if needed) update the SDK project from an old version to a new one	Recreate SDK project using the new exported HW project
	Generate a new link script
	Download the bitstream to the FPGA
	Run the demo project
Check the fiirmware of FX2 microcontroler

⁽¹⁾ It depends on which computer is used (workstation, regular PC or low-end PC).

• If the FX2 microcontroller has not been programmed before, please follow the instructions here and here. You can use Cypress, Python OpenFut or C# OpenFutNet programs.
• If you are sure that the FX2 microcontroller is properly connected, you can connect to the TE USB FX2 module with a JTAG adapter cable. We recommend using the Xilinx Platform Cable USB.
• Then connect the TE USB FX2 module to a USB cable.

Use the demo project without the XMD UART

To use the demo project without the XMD UART, you need to use "RS232" instead of "debug_module" as standard in/out port. Otherwise the application running on the Microblaze processor freezes if you disconnect the XMD. To accomplish that you need to set up the Microblaze "Software Platform Settings".

• In the dialog window select "OS and libraries" in the left window and pick "RS232" as a stdout and stdin interface.
• Then rebuild the software and download again the project to the FPGA.
