Hello Mats,
those functions might be called indirectly. All what I need is in the
main-loop:
// poll ethernet
cs8900if_service(&myethif); // AX88796 driver (polling mode)
// poll ethernet slow timer every 250ms
if(core_get_tick() > (eth_tick + 2500))
{
tcp_tmr();
eth_tick += 2500;
}
This code polls the Ethernet chip and handles accordingly via call-back
functions.
Periodically tcp_tmr() is called to clean unused blocks etc.. You might
look where this function is called ....

In our project we use lwIP to send UDP packets, and lwIP also handle
ARP, ICMP, IP fragmentation... All example code and documentation I have
read include a timer in the projects, but I have tested our design
without timer, and it works fine. Do I have to include a timer in the
project?
I have read that etharp_tmr() and ip_reass_tmr() must be called. Our
system is working fine without, but will it crash later because we don't
call the timer functions? Do we have to call them or do the Xilinx
adapter functions call them? I have tried to read the source code for
lwIP, and it seems like the timer functions are called only if NO_SYS =
0. Am I right? Are there other timer functions we have to call?
We use lwIP 1.3.0 on a MicroBlaze processor without OS on a Spartan 3A
DSP 1800 FPGA.
