Superloop w/Cyclone 2c35 w/LAN91C111

I am trying to implement the Superloop into a Custom Board using a Cyclone II (2c35) and using the LAN91C111.

I would like to create an application using Nios 2 IDE Version 9.0, where I can implement the superloop.

I was able to download/modify/run the example as shown in the nioswiki/superloopsimplesocketserverplus forum for the kit development board 3C25N.(DK-N2EVAL-3C25N-0H) Not a problem. I don't know how to convert it down to the 2c35.

Any help will be appreciated it.

Thanks!

    A good starting point could be the 2c35 Dev Kit(DK-NIOS-2C35N-0H). I can easily adapt it from the dev kit to the custom board.

    So far I have been able to:

    1. Downloaded/unzipped the source file directories from 20090611_superloop_sss_plus_neek_90sp1.tgz. These source files contain the hardware image for the neek eval board(3C25) and scripts for generating the project for that development kit.

    2. Replaced the files with .sof, .ptf, and .sopcinfo with the ones for the 2C35 Dev Kit.

    3. Modified scripts from the app folder and bsp folder (including subfolders) to match the 2c35. The tricky part was the TSE and RAM. Removed references to flash/rozipfs. Removed any reference to the graphics display and demo.c.

    4. Hardcoded the mac_address/ip_address.

    5. Used the nios command shell under the app directory... Typed ./create-this-app. The project compiled succesfully(after multiple times) Generated the bsp and superloop_iniche and superloop_lan91c111 libraries.

    6. Downloaded to the board using the JTAG.

    Board did not connect to the network. I was unable to import it to NiosIDE and debug.
