Re: [lwip-users] LwIP tcp_output Pcb Corruption

Hi –

 

Thanks for the response.   Do I get rid of ETH_IRQHandler altogether?  It checks for input, calls ethernetif_input which calls low_level_input and ethernet_input (setup in netif_add) then clears the ETH_DMAs.  Do I move this all to the main loop?

 

Thanks in advance-

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.
