Introduction
This tutorial shows how to compile and program the webserver_camera demo application on the FPG-EYE bord (the one that is pre-loaded on the board).
To begin with this tutorial: install Mico32/FPG-EYE development environment, get a local copy of ERIKA Enterprise repository and then follow the Tutorial: Building a Mico32 platform for FPG-EYE.
Below mentioned paths are all relative paths of the local ERIKA Enterprise repository.
Create Mico32 Library for fpg_eye_mico32 platform
After importing fpg_eye_mico32 platform in LatticeMico System software, switch to C/C++ Perspective. Right click to open the C/C++ Project View and select New->Mico32 Library Project command:
Make sure to select the correct target hardware by selecting ee\examples\mico32\demo\platforms\fpg_eye_isplever\msb\soc\fpg_eye_mico32.msb if you are using ispLever tools else ee\examples\mico32\demo\platforms\fpg_eye_diamond\msb\soc\fpg_eye_mico32.msb if are using Diamond tools. To compile the fpg_eye_mico32 demo without making any changes to the project files, select the follow directory as library location ee\trunk\ee\examples\mico32\demo\platforms\fpg_eye_isplever\library (if you use ispLever tools) while ee\trunk\ee\examples\mico32\demo\platforms\fpg_eye_diamond\library (if you use Diamond tools)
and fpg_eye_mico32 as project name:
Build the brand new project:
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.
Please note that lm32-elf-objdump may fail with a segmentation fault. You can run make output/out.elf (where output is the output folder) instead of make all to avoid the execution of the objdump step.
Program the flash with send_prog.py bootloader script
Before flashing the application with send_prog.py bootloader client script, you need to connect the FPG-EYE board with a serial cable too you computer. Use serial-to-usb coverter if required:
After connecting the board with serial cable, get the send_prog.py script from FPG-EYE Software Packet and copy it in a directory under your cygwin environment path. Open a cygwin shell in webserver_camera project directory output and execute the following command:
send_prog.py --flash /dev/comX out.elf
Note: Change the comX value to that of your actual com port value.
When the script is launched, it is not synchronized with the bootloader, and it should look like:
To synchronize the script with the bootloader, hold down Button 1 and push the reset button.
The application is saved on FPG_EYE external flash as shown below, and the bootloader is ready to read and copy it in XP2 ram.
Test webserver_camera demo application
Connect Ethernet cable to the FPG-EYE board. The webserver_camera demo has ethernet address to 192.168.0.2. Change your local net address to the same subnet of the FPG-EYE board.
Open a web browser window and type in the address bar http://192.168.0.2:
Test demo_camera application
In the Erika repository you can find a demo with camera more simpler than webserver_camera. The demo uses the camera and the uart serial port without the ethernet interface. Its location, in the Erika repository, is as follows: /ee/examples/mico32/demo/sw_projects/demo_camera. To use this demo you have to follow the same steps described above about web_camera application. After you have loaded the program via bootloader, open HyperTerminal program and select Text acquired... in the Transfer menu voice.
Now please select the place where you want storage the camera picture. Important: the file extension must be PMG!!! (something like this: <file_name>.pmg).
