Overview

This demo is a Webserver which utilizes SmartFusion2 SoC ARM Cortex-M3, Ethernet, USB / COM-port, Real Time Clock and the on-board LEDs.

The demo is offered in two variants, one which is stored into the embedded non-volatile memory (eNVM) and the seconde one which stored to the external DDR3/L SDRAM memory and therefore volatile.

Download

The Trenz Electronic Reference Designs and Demos are usable with the specified Libero / SoftConsole version. Usage of a different Microsemi / Libero / SoftConsole software versions is not recommended.

Reference Designs / Demos are available via the following link:

• TEM0002_Reference Designs/Demos

The download is a ZIP compressed archive. Extract the archive before usage.

Design Flow

The Hardware and Software Reference / Demo -Designs Projects are available as a prebuild zip archive. The archive contains at least a Libero Hardware Project and a SoftConsole Workspace folder, they were created and tested in windows environment.

This SoftConsole Workspace contains the Software Reference Design Hello World and the Demo Webserver, the demo is offered in two variants. For software development via the IDE SoftConsole a board configuration file "microsemi-smartfusion2-smartberry-ddr.cfg" is included.

Board configuration file

Copy the board configuration file "microsemi-smartfusion2-smartberry-ddr.cfg" along the following default installation path inside you Microsemi / SoftConsole installation into the folder board:

C:\Microsemi\SoftConsole_v6.2\openocd\share\openocd\scripts\board\

Launch

Executing a Reference / Demo Design on a module requires the powering of it and a JTAG or UART Connection for Programming and Communication. Often the programming is a two fold process, where the first programming configures the FPGA and the second programming flashes Software code to be executed inside the FPGA / ARM processor.

Connecting

Connect the modules micro USB connector to your host pc, this enables the powering of the module and a simultaneous JTAG and UART connection .

Only necessary for running the Demo Webserver:
The demo is configured to establish a network connection via the DHCP protocol, therefore, if a a free router port is used, no further port setup is required.

If a "direct Ethernet Connection" between Host PC and module is used, the user must know how to setup this connection type. Further down in this chapter is explained how to setup the Demo Webserver and recompile it, so that it uses a static IP.

Driver check

When the module is connected via USB cable to your demo host computer, in the Windows Device Manager appear the following tree board driver related devices:

In section Ports (COM & LPT):

• FlashPro5 Port (ComX)
  

In section Universal Serial Bus controllers:

• USB FP5 Serial Converter A
• USB FP5 Serial Converter B

The Device Manager is accessible via "Right mouse click context menu" from the Windows Start Menu Button.

Programming Hardware design

Open Libero 12.4, in the to left corner, open the Webserver Demo hardware project inside the extracted ZIP download via   "Project > Open Project" and point the file dialogue to the demo archives hardware project:

Disk :\ Path-to-the-Demo-archive \ Extracted ZIP-archive \ Libero-X.y_Referenz-Design\

double left mouse click onto the project file "Referenz-Design_XY .prjx" to open it. The board is automatically selected and setup to be flashed by Libero.

In the upper left section of Libero, select the tab "Design Flow" (picture above - green rectangle) and flash it to the board via   "Program Design > and double left mouse click onto   Run PROGRAM Action" (picture above - row with blue background).

Warnings should not affect the functionality of a Reference / Demo -Design.

UART connection

Before flashing the Webserver Demo server application to the module, open a comport terminal to the boards comport, so that it's messages about the used IP Address and executed Demo-Variant can be captured.

demo into the module is a three fold process, programming the FPGA Design, establishing a COM-port terminal connection to the module and programming the web server program code into the modules FPGA's embedded flash or it's external DDR memory.

Programming Software project

Open SoftConsole 6.2 and press "Browse..." to point the "Workspace: " to the folder "Softconsole-6.2-Workspace" inside the demo folder.

Disk:\Path-to-the-Demo_archive\Softconsole-6.2-Workspace\

Subsequently the program opens and shows the software project's who are contained inside the workspace to the left, under "Project Explorer".

The demo is offered in two variants:

• Smartberry_Webserver_6.2 - Application code is stored to the FPGA's embedded non-volatile memory (eNVM)
• Smartberry_Webserver_DDR_6.2 - Application code is stored to the FPGA's external volatile memory (DDR3/L SDRAM) and lost during power down

Before flashing the demo, open a comport terminal to the boards comport, so that its messages about the used IP Address and executed Demo-Variant can be captured.

To simply run the demo press the triangle right to the button marked with a "R" in the picture above and select a variant of the demo.

MOVE up to beginning!!!!!:------------------------

Pressing the triangle next to the button marked with "D" let you select which variant to be executed in debug mode.

Debug controls - Resume - Pause - Stop

Switch between Debug and Run perspective (upper right corner program window)

Demo Variants

The two demo projects "Smartberry_Webserver_6.2" and "Smartberry_Webserver_DDR_6.2" are identical variants of the demo, they only differ in their memory location. The first one is stored in embedded non volatile memory (eNVM) and the later is stored volatile in the external DDR ram and therefore lost during power down.

Static IP configuration

To disengaging the DHCP mode one has to setup up an IP and Gateway Address in the code unit "main.c" line 274. Alternativly, the demo hosts IP Address can be changed.

Furthermore the corresponding compiler flag needs to be deleted in the project setting. To do so, in the "Project Explorer" tab, right mouse click onto the project and select Properties in the appearing menu.

In the left section of the properties window select "C/C++ Build   >   Settings" in the right section select the tab "Tool Settings   >   GNU ARM Cross C Compiler   >   Preprocessor" under "Defined symbols (-D)" delete the compiler flag "NET_USE_DHCP" and press "Apply". Confirm the following dialogue and press "Cancel".

Lastly, the project needs to be recompiled. In the top menu of the SoftConsole select "Project   >   Build ALL / Build Project".

Warnings should not affect the demo. can be ignored.

Pictures of the Webserver pages

Open a new tab in a web browser and enter the IP Address from the comport terminal. The start page, picture below, should appear immediately.
