Re: [lwip-users] LwIP tcp_output Pcb Corruption

[mary_west]

Ok – nevermind last email.  I need the ETH IRQ handler.  In there, I load an application list (not an LwIP pbuf) with the received ETH packet and clear the ETHDMA bits to get the next interrupt.  In main, I get the packet out of the list and call ethernet_input to have LwIP handle it.  Is this how it should be done to avoid problems in tcp_output?

 

Thanks-

Mary

  I read this in the archive as part of an answer to a question about a similar input problem:

  "When running without an OS, you have to put new packets on a linked list that is processed

  periodically from main() (just like the timers)."  Is this true for outgoing tcp packets?

 

No, it means don't call ethernet_input from the interrupt but from the main loop, too.
