Introduction

The reference architecture can be tested in two ways:

  • USB communication tests + DMA tests
  • full test (USB communication tests + DMA tests + other tests)

JTAG and USB connections

Two types of connections are available:

  • USB connection (USB (host computer) ↔ USB (TE USB FX2 module))
  • JTAG connection (normally a JTAG adapter cable; we recommend using the Xilinx Platform Cable USB (USB (host computer) ↔ JTAG (TE USB FX2 module)) ;

Xilinx EDK/SDK and iMPACT (or equivalent XMD console commands) could be used to develop/generate an FPGA bitstream (with MicroBlaze's processor and software "merged" into an FPGA bitstream). When the FPGA bitstream is ready, either the USB or JTAG connection could be used to write the SPI Flash memory of the TE USB FX2 module (i.e. download the FPGA bitstream into the SPI Flash memory).

The JTAG connection could also be used to directly download the FPGA bitstream into the FPGA without the need of a reset.

The JTAG connection could be used with Xilinx EDK and SDK GUIs for development and debug purposes; XMD console could also be used.

The USB connection CANNOT be used with Xilinx EDK and SDK GUIs for development and debug purposes. The USB connection should be used after the development and debug process.

With a JTAG connection, the development and debug phases are easier.
Without a JTAG connection, the user/developer should create/use custom functions/programs for the debug phase but some JTAG debug features may not be easily replicated through a USB connection.

Info
Use of JTAG connection is NOT necessary.

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 ???).

For an example see here.

Info
Use of JTAG connection is necessary.

To completely test the Reference Architecture is necessary:

...

The procedures are the following (a TE0300 board case is described).

        

.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)

Tip

For old version of Xilinx EDK with older version of Project Reference (they do no longer exist on GitHub) the procedure is the folowing

  • Open the project by double-clicking on the system.xmp file. The Xilinx Platform Studio is opened.
  • If you open the project with a new version of Xilinx XPS, the tool will try to update all the components of MicroBlaze system. In some case it is not possible to refuse the update.
  • To compile the project press the "Download Bitstream to the FPGA" button.
  • If the HDL design was successfully implemented and downloaded to the TE USB FX2 module, you can proceed to compile the MB software. Press the "build all user applications" button.

To use the "demo" application contained in TE0xxx-Reference-Designs\reference-TE0xxx\SDK\SDK_Workspace, you should (1) copy GitHub's "TE-EDK-IP" folder (from https://github.com/Trenz-Electronic/TE-EDK-IP) to the folder that contains the folder "reference-TE0xxx":

Tip
titleChoice assumed in this step and in the following ones.

From now on, the choice (1) is assumed.

Check the firmware of FX2 microcontroler

The FX2 microcontroller on the TE USB FX2 module should contain valid firmware before proceeding.
