RE : [lwip-users] arter getting error sys timeouts in the funtionsys_arch_timeouts()

[Frédéric BERNON]

The problem is you should never return NULL with sys_arch_timeouts(). If you enable assert, you should got this message :

 

"sys_timeout: timeouts != NULL" (from sys.c, line 206).

Objet : [lwip-users] arter getting error sys timeouts in the funtionsys_arch_timeouts()

 

 

Hi,

 

    I'm using lwip cvs update, My software and hardware is at91sam7x256 + ucos + lwip,

I'm committed to the stability of the test lwip. my target board connects to company's LAN, so it can recieve a lot of enthernet data. sometime, when lwip get the timeouts error by the funtion sys_arch_timeouts(), I return NULL, and then, lwip doesn't work well, it debugs out information

 

    memp_malloc: out of memory in pool PBUF_POOL

 

forever!

 

    I want to known when the funtion sys_arch_timeouts() gets the error timeouts, what can be return?

 

 

    My second question is in the funtion netconn_recv(). I don't use socket, so when I want to receive data, netconn_recv() is been called. In the funtion, first it asks a buf, then waits for data coming forever. sometimes, I want to close the connect in another task, but the funtion netconn_recv() doesn't return, and the buf doesn't free forever!

 

Thanks.
