Re: [lwip-users] help: how to use interrupt in RAW_API mode under Xilinx-V2

[ye wu]

Hi, all

 

I'm now trying to do the interrupt in Standlone, but still without success.

 

It seems that the interrupt work well, i put a print in the handler and we can see the handler was called several times.

 

but when a interrupt come, the handler do nothing.

 

i turned on the debug of lwip and find something strange in the init of lwip, there ware lots of 'pbuf_alloc: allocated pbuf' but i haven't seen any free of them...

i find out latter that this pbuf_alloc hapens at

if (init(netif) != ERR_OK) {
    return NULL;
  }

in the netif_add() function. the init function is the xemacif_init() that given to it.

 

i don't know why this happens, could anybody help me ?

 

Thanks a lot!

 

 

 

the output of my terminal is:
