I tried to change the parameters but without success. In same time I port to lwip 1.4.0, and I corrected some minors bugs in UDP services by changing "rcv" by "rcvfrom" but it didn't change anything.
The problem appears only when the others services are activated. In webserver only it works correctly. Should be the problem comes from the UDP loop? Vincent, Like you said the problem could be come from driver but I used a code with modifications: http://lwip.100.n7.nabble.com/STM32-RBUS-Receive-Buffer-Unavailable-bit-set-after-debugger-break-td11154.html#a11161 Thank you, Pierre -- View this message in context: http://lwip.100.n7.nabble.com/webserver-problem-tp21697p21707.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
