Superloop Simple Socket Server with LAN91C111 ---> Success!!! <---

I'm working with the 2C35 Nios Dev Kit. It uses the LAN91C111 mac/phy.

I downloaded the "Superloop Simple Socket Server Plus" project from Altera Wiki

(http://www.alterawiki.com/wiki/superloop_simple_socket_server_plus?gsa_pos=1&wt.oss_r=1&wt.oss=superloop), or go to www.altera.com (http://www.altera.com), search "superloop".

On the hardware side, I use the niosII_cycloneII_2c35_standard project that comes with the dev kit. On the software side, the project has to be modified to use the LAN91C111 instead of the TSE mac. That's the tricky bit.

In the create-this-lib script in sss_tse_lib (I renamed this dir to sss_smsc_lib), change ORIG_SOURCE_DIR

ORIG_SOURCE_DIR="${SOPC_KIT_NIOS2}/../ip/altera/sopc_builder_ip/altera_avalon_lan91c111/"

Change the file listings:

# # Source file listings...#

HAL_FILES="

# UCOSII source files

UCOSII_FILES="

In iniche_init.c, change # include "triple_speed_ethernet.h"

to# include "altera_avalon_lan91c111_iniche.h"

change

TRIPLE_SPEED_ETHERNET_INSTANCE ( TSE_MAC, tse_mac);

to

ALTERA_AVALON_LAN91C111_INSTANCE ( LAN91C111, lan91c111);

change

TRIPLE_SPEED_ETHERNET_INIT ( TSE_MAC, tse_mac);

to

ALTERA_AVALON_LAN91C111_INIT ( LAN91C111, lan91c111);

... and probably a few other things I'm forgetting.

The critical thing I had to overcome was I was originally# include-ing altera_avalon_lan91c111.h instead of altera_avalon_lan91c111_iniche.h. This file also contains declarations that will allow the project to compile, but it results in the following message when I run:

prepared 0 interfaces, initializing...

inet startup error: unable to find any working interfaces

dtrap - needs breakpoint

panic: IP

altera_avalon_lan91c111_iniche.h contains different _INSTANCE and _INIT that make all the difference.

Now I can make LEDs blink from a distance without the need for MicroC/OS-II. My life is complete.

I hope this helps someone!
