Hello,
I use lwIP 1.3.2 with CMX as OS on the STM3220G-Eval board. I use the example
from ST with the changes from Mark Lakata and an OS port for CMX. CMX is
running with an cooperative scheduler.
So now I tried successfully a ping to the board. But when I started to add the
HTTP server application I run in a big problem. The TCP Task won't get
scheduled and the application reach the accept statement and throws and error
message. This happens again and again (the accept statement is in a while(1)
loop). I assume that I have to setup lwIP in a way to support cooperative
scheduling. Im more detail: How can I synchronize the HTTP and the TCP tasks
(in the freeRTOS example the TCP task gets scheduled and give the output
"tcp_bind: bind to port 80").
