TEM0002 Webserver Demo1

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.

Refer to http://trenz.org/tem0002-info for the current online version of this manual and other available documentation.

Design Sources

Download

The Trenz Electronic Reference Designs and Demos are usable with the specified Microsemi 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 a Libero Hardware Project and a SoftConsole Workspace folder, they were created and tested in windows environment.

This SoftConsole Workspace contains the Software Project Hello World and the Demo Webserver, the demo is offered in two variants. The board configuration file "microsemi-smartfusion2-smartberry-ddr.cfg" is required for the usage of the Software projects via the IDE SoftConsole.

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. When these devices are not visible, the driver installation through libero could be faulty.

Programming the Hardware design

Programming of the Hardware reference Design requires to open the FPGA Design IDE Libero

The Hardware Reference Design can be opened via   "Project > Open Project" in the top right corner of Libero (picture above - upper green rectangle). A file dialogue opens, point the dialogue along the extracted download to the folder containing the Hardware Reference Design.

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 - lover 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 any Software Project to the module, open a comport terminal to the boards comport, so that it's messages can be captured.

Programming a Software project

Open SoftConsole and press "Browse..." near the right edge. A file dialogue opens, point the dialogue along the extracted download to the folder containing the SoftConsole Workspace.

Disk :\ Path-to-the-Demo-archive \ Extracted ZIP-archive \ Softconsole-X.y-Workspace \

Confirm your selectioin by pressing "Ok" , the dialogue closes, and open The SoftConsole by pressing "Launch"

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

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

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

Application

Demo - Webserver_...

The demo projects "Smartberry_Webserver_X.y" and "Smartberry_Webserver_DDR_X.y" are identical variants of the demo, they only differ in their memory location:

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

UART output:

Static IP configuration

To disengaging the DHCP mode one has to setup up an IP and Gateway Address in the code unit "main.c" roughly at line 270. 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.

Reference Design - HelloWorld_...

Hello World example as endless loop instead of one console output. Each loop lights up each LED. The user buttons responds with a message at any time.

UART output:

COM-port Terminal "Hello World loop"
