Hi Simon,
What is the preferred way to send data from within LwIP context.
Beside running sys_timeout and hooking a function to it ?
If I want to send data at a high rate and I will set sys_timeout to say 1ms it will cause load
on the system. Is there another clean way to do it ?
BR,
Noam.

I guess so. That would mean you don't use an OS but use lwIP in NO_SYS=1 mode.

That would mean you call the lwIP TX functions from main loop while calling the RX functions from ETH RX interrupt. That's not supported and this most probably is your problem.
