Hi, I am facing a new problem concerning TCP. TCP were perfectly running until I changed MTU on my netif and the size of Pbuf. The problem is when chained pbuf are used. From my debug trace I saw pbufs correctly allocated and chained. But checksum failed and when my app tried to print data I got Hardfault as gift.
/Before:/ (no need of chained pbufs since max frame size is equal to pbuf size) netif->MTU=128; #define PBUF_POOL_BUFSIZE 128+14+2 /After:/ (need chained pbufs) netif->MTU=256; #define PBUF_POOL_BUFSIZE 128+14+2 Note that I have about 30 pbufs in my pool. Thank in advance for your help, Peter. -- View this message in context: http://lwip.100.n7.nabble.com/UDP-reception-problem-tp21624p21693.html Sent from the lwip-users mailing list archive at Nabble.com. _______________________________________________ lwip-users mailing list [email protected] https://lists.nongnu.org/mailman/listinfo/lwip-users
