Hi Everybody
I am facing a problem concerning UDP reception. After have written my
driver, I am currently testing it and things worked well until UDP test. Let
me explain:
_ARP is correctly running
_ICMP is correctly running
_IP is correctly running
_UDP *broadcast sending* is correctly running through netconn API
_UDP *reception* doesn't work at all through netconn API
_UDP *reception* receives *one * packet through RAW API then crash at the
second UDP request(ICMP not reachable sent)
I am using the latest release of lwIP in multi-threading with FreeRTOS
Could anybody help me? Note that I'm working on embedded system and don't
have standard output... but these are my settings from lwipopts.h :
