Re: [lwip-users] problem with multiple UDP sockets

Hi,

Im trying to run a demo of LWIP with ChibiOS on a Olimex STM32 P107 revC, but Im getting the following behaviour:
- for the first ~10s both RJ45 leds blink (slowly)
- then green led is turned off, orange blinks fast (the board is receiving packets) and then is kept on
- I'm unable to communicate with the board (ping doesn't work)

The demo includes an http server.

I enabled all the debug switches of LWIP to try to understand what's happening in the stack but Im unable to extract meaningful information from the output (see below). Can somebody help me understand what's going on? For the received packets the stack says "packet not for us".

I'm running FreeRTOS 8.1 with LwIP 1.3.2.

In one of my threads, I create 2 UDP sockets (using netconn) with different port numbers.

One of them I connect to INADDR_BROADCAST (multicast transmit) and the other I bind to INADDR_ANY (receive from anyone).

Ideally, I would use the same socket, but I found that it did not work.

With 2 sockets, only the one that I create first works.

If I create my Tx socket first, then my Rx socket will report back an ICMP message that the port is unreachable.

If I create my Rx socket first, then I can receive, but my netconn_send() call will block.

Any ideas on what could be happening here?

Thanks.
