Hello all, I'm using lwip on a stm32F767 based board and encountered some issues that I don't know where to start debugging.
This board opens some TCP ports that clients (linux program) can connect to and exchange information. In one occasion 2 of the ports started to fail the initial connection -- I've tried both blocking and non-blocking sockets on linux (handling EINPROGRESS) to no avail. Nonetheless if I try to connect to these same ports with netcat I can get a connection and exchange data. With wireshark I noticed that when using my program it sends a SYN but gets no *SYN,ACK *from lwip. The same does not happen with netcat and good connection is achieved. Is there more data or configuration I can share? Did someonelse encounter a similar problem? Thank you -- *Software EngineerOceanScan - Marine Systems & Technology Lda* *Av Liberdade, Polo Mar UPTEC4450-718 Leça da Palmeira, Matosinhos, Portugalwww.oceanscan-mst.com <http://www.oceanscan-mst.com>*
