Re: [lwip-users] lwip_write() blocks indefinitely

Hi Alhad,

 

Maybe one reason.

Output driver overrun- packet are sending, but second packet overrun first.

Try do test with delay:

while(1) {
    lwip_write();

    delay(10ms);
}

 

Please, write about your system-hardware.

Darius

Any reason why this would happen?

Hi,

I am using LWIP 1.4.1 and we are seeing a situation where lwip_write()
blocks indefinitely.

We are using a tcp socket, connecting to a remote socket. and then calling
lip_write over and over.

lwip_socket();
lwip_connect()
while(1) {
    lwip_write();
}

The server is the netcat command running on a mac host.

In what situation would something like this happen?
Would this result because of improper configs in our lwipopts.h file?
Is there a cap on the size of the data buffer being passed to lwip_write?

Thanks,
Alhad
