i'm seeing a strange problem. I have lwip 130rc1 and i'm using socket.
recv function seems works well, but i have a strange behaviour of lwip_send function.
if i write:
send(newsockfd, &buffROM, len, 0);
where buffROM is a vector in ROM, data are sent.
if i write
send(newsockfd, &buffRAM, len, 0);
where buffRAM is a buffer in ram modified in run time (it's build in my application using data in ram) lwip seems doesn't send packet with these data. (i 'm using a protocol analyzer to capture packet in network... network is simple, only a pc, my board connected through an hub)
