Hello,
The system that I am working on has a web server hosted on the TM4C129XNCZAD microcontroller. The client sends periodic HTTP requests to the server each 5 seconds. Sometimes the TM4C board crashes and I want to get to the root cause.
I investigated the crash info and it led me that it happens in the following API from the NDK stack: SockPcbFind ,
Specifically at the following condition:
/* Local port NULL means socket is not bound */
if( !ps->LPort )
continue;
I assume that the rate at which the client sends its requests to the server might be fast (every 5 seconds), Is that a possible reason for the crash?
Here is the crash info:
