Introduction

The goal of this tutorial is compile and program the webserver_camera demo application on FPG-EYE bord, the one that is flashed on the board when you get it. Before you can afford this tutorial you need to install Mico32/FPG-EYE development environment get a local copy of ERIKA Enterprise repository and to follow the Tutorial: Building a Mico32 platform for FPG-EYE that is a prerequisite for this one. Hereunder all paths listed are relative paths to yours ERIKA Enterprise repository local copy.

Create Mico32 Library for camera_debug_50 platform

After importing camera_debug_50 platform in LatticeMico System software, switch to C/C++ Perspective, open the C/C++ Project View context menu (right click with the mouse), and find New->Mico32 Library Project command (as the following figure):

C/C++ New Mico32 Library Project

On opened wizard assure to select the right target hardware selecting ee\examples\mico32\demo\platforms\camera_debug_50\msb\soc\camera_debug_50.msb file. To compile the camera_debug_50 demo without any changes on project files you need to select the follow directory as library location ee\trunk\ee\examples\mico32\demo\platforms\camera_debug_50\library

C/C++ Mico32 System Library Project Wizard

and camera_debug_50 as project name:

Build the brand new project:

Compile the Mico32 library

Create webserver_camera demo project

Create a Mico32 Standard Make C Project in ee\examples\mico32\demo\sw_projects\webserver_camera directory and build it.

Program the flash with send_prog.py bootloader script

Before to flash the application with send_prog.py bootloader client script, you need to connect FPG-EYE board with a serial cable too you computer ( you could need a serial-to-usb coverter):

FPG-EYE Board serial connector

FPG-EYE custom serial cable

After connect the board with serial cable get the send_prog.py script from FPG-EYE Software Packet and copy it in a directory in yours cygwin path, start a cygwin shell in webserver_camera project directory output and execute the following command:

send_prog.py --flash /dev/comX out.elf

N.B You have to change the comX value with yor actual com port.

To synchronize the script with the bootloader you need to hold Button 1 and hit reset button.

FPG-EYE Buttons

After following message, your application is saved on FPG_EYE external flash, and the bootloader can read and copy it in XP2 ram at the start.
