I'm a student of University of Tunisia and I'm using IAR Embedded Workbench for ARM, v. 7.10, 32K Kickstart Edition on WIndows 7...

I am

currently

alternating

,

and my

first

project is to

establish communication between

my computer

and

STM3221g-eval

ethernet

connection

.

 

I

focused on creating

blocks

of the function that

will allow

to transform

a file request

by my client

(web

browser)

on appeal from

subroutine.

    There should be a couple of ethernet examples under the Design Resources of the F2 chip you are using. For example the LwIP and IAP ones, the former has a simple web server, this could be modified using other code in the firmware library to read data off an SD card. I think I've had a discussion about an F2 or F4 (near identical for interfaces) http server using files off a card.

    Google ''STM3221G-EVAL''

    http://www.st.com/web/en/catalog/tools/PF251702

    Click ''DESIGN RESOURCES'' tab

    Download board and platform examples

    Google ''

    STM32F217IG

    ''

    http://www.st.com/web/en/catalog/mmc/FM141/SC1169/SS1575/LN9/PF250172

    Click ''DESIGN RESOURCES'' tab

    Search ''TCP'' or ''LWIP''

    http://www.st.com/web/en/catalog/tools/PF257896

    Scroll to the bottom, Click DOWNLOAD

    There should be examples in there of a web server, and other TCP/IP examples, using Ethernet, and initializing your board's hardware. REVIEW

    Ok,. you'll want to review documentation for your board, and any associated README.TXT type file with the source. You might have to configure specific jumper setting, or settings within the code, depending on how the clocks are generated (external crystal vs MCO pin PA8), MII/RMII modes of PHY, etc.

    Think also how device is cabled. Standard cable to a hub/switch, a cross-over cable if connected directly to a PC. The latter might also have issue with the assignment of IP address fixed, or via DHCP. I would generally connect to a router/nat type device that provided DHCP based IP in common subdomain to PC and EVAL board.

    clive1,

    thank you very much for your advice ..

    the problem is that I am a beginner in the world of stm32 and I must make an application in 5 days establishing the communication between the board stm3221G-EVAL and a client { web browser} ethernet connection

    with the notion of the web server.

    I know this is a stupid app for you , but I find it difficult to achieve.

    If you can

    spend some

    of your time to

    help me

    and i would be grateful

    thanks.

    Still, you really should be old enough to do this by yourself, and I learn nothing from the exercise.

    Make sure your board is jumpered correctly, and that the software you are building has the right configurations. That the network setting for the MAC and IP addresses are appropriate for what you are attaching it too. If this is not a new board you might want to check the clocks look right and nothing has been modified.

    but the problem of

    the initiation of

    ethernet

    remains

    ...

    I get

    always

    I don't have your board, you'll need to get a scope out and verify you have the clock signals where you expect them, and the jumpers as required.

    Then you want to use your debugger, and understand at what point, and for what reason, the initialization fails. The software in question is designed for your board, be sure to pick the ''STM3221G-EVAL'' as the target.
