Changing from NicheTask to Superloop

[tobiasplayer]

Has anyone ever backed out the NicheTask and got the NicheLite TCP/IP stack running with SuperLoop? If so, what steps did you take? I've been able to remove the NicheTask, get the code to compile, but it seems like the NicheLite stack is not running.

Thanks,

Bob

A bit more details about "my stuff": GCC from CodeSourcery and usage of M52235EVB. From ethereal sniffing, the 52235 sends an ARP request for the configured gateway address, and receives a valid reply to this.

I guess this is parts of the answer (correct me, if this is incorrect):

• use power-up code similar to the niche web-server (without the tasks and web-server)
  
• call inet_timer() from timer_isr()
• call packet_check() from timer_isr() (??)
  

These attempts on simple low-level data transfer has failed:

• send data with udp_send() (no relevant data found in ethereal)
  
• receive data by using udp_open() and waiting for callback function (no callback)
• listen on TCP port with m_listen() and wait for connect (no callback when attempting to connect to 52235 with netcat)

Does anyone have a tip or success story to share with us?

Here is a dump of (strategic) parts of my "ipport.h" file:

I am struggling with the same problem. Any help regarding this would be greatly appreciated.
