Hi Guys,
I am trying to get a simple code to control the LEDs on the Spartan 3E's board from a PC using Ethernet (just to get the communication working, later I need to control some GPIOs based on that code).

I am not an expert on Ethernet protocol and don't seem to be able to get the communication working properly. I am sure I can do it, but I would rather use an example to build on rather than do the whole work myself (really under time pressure).

Does anyone has done a similar project who can share?

Thanks in advance for your help,

/Farhad
PS. as I said I reward the person who send me the working code 200 points, I know it is not much but this is just an appreciation for your help.

Did you get the ethernet connection to work? I'm trying to create an ethernet connection and don't want to start from nothing and rather work of an example as you had stated in your post.

Thank you for your time in advance.

Check the examples at **broken link removed**
I have run the Lightweight IP Library. Check the closet example to your chip and EDK tool version and play with it.

I have actually tried this example, however was unable to get it to work. Do you have any other suggestions?

Which example exactly do you have?
Which example did you run?
I can help you.

Hi Guys,
Sorry for the long delay, I didn't follow this for a long time.

I gave up on EDK. It is so unreliable buggy that I completely left that environment (especially now that I no longer working for a company who believe Xilinx is the messenger of God and EDK is the new testament).

I heard that most of the problems with the EDK and the SDK are now solved when you move on to Ver 11. But as I said, I no longer have the SW platform and can not participate in this discussion.

Best regards,

Re: Xilinx EDK-Ethernet-PC = 200 points for a working exampl

I got to the part where I'm in SDK, downloaded the bit stream to the FPGA and ran the debug. The following message appears in the hyperterminal from the serial connection:
-----lwIP TCP echo server ------
TCP packets sent to port 6001 will be echoed back
Board IP: 159.62.134.10
Netmask : 255.255.0.0
Gateway : 159.62.134.1
tcp echo server started @ port 7

However, this is the last response and when I open a hypertermail window to connect to the eithernet port so that i can write something to see echo back--I'm unable to connect to the designated ip address.

Please let me know how i can fix the problem or if you need additional information about my situation in order to help debug more.

You have a working example of the echo server.
If you want to modify the application, you have to modify the code of the echo server yourself.

I do not have a working example. The only response I can see from the board comes from the com port. I am unable to connect via the ip address of the board through hyperterminal.

Do you have any suggestions?
