Hello lwIP-users!
I am working on a small project with the AVR32UC3A-processor from Atmel.
Everything's fine so far and it is really nice to see an implementation
like lwIP.
I tried to run an example available within AVRStudio5, a simple
tftp-Server, and within this project, I tried to open multiple sockets
at a time.
The example uses lwIP-1.3.2.
It seems like lwIP does not like this. As soon as I open more than one
socket, the return value of socket is negative.
Doing this won't work:
t = socket(AF_INET, SOCK_DGRAM, 0);
if (t < 0) {
vParTestSetLED( 6 , pdTRUE );
return;
}
s = socket(AF_INET, SOCK_DGRAM, 0);
if (s < 0) {
vParTestSetLED( 7 , pdTRUE ); //grün
return;
}
The system I am working on (Atmel EVK1100) will light up LED No 7, which
means, the second socket-call fails.
What might be the problem? Is there a restriction within lwIP regarding
the amount of possible open sockets?
Thanks a lot for any help!
Dennis
