Dear Colin,

I wonder  if i have the same problem (Adding new entry in timeout table....How?) 

I am trying to run the UDP server in Xilinx Spartan 3E Starter Kit.

I had run the Build Project on the XPS EDK8.2i. It shows the following timeval Errors:

 

At Local date and time: Wed Mar 21 00:23:01 2007
 xbash -q -c "cd /cygdrive/d/EDK8.2i/EDKexamples/sp3e1600e_mb_webserver/; /usr/bin/make -f system.make UDPServer_program; exit;" started...
mb-gcc -O2 UDPServer/udp.c  -o UDPServer/executable.elf \
-mcpu=v4.00.b     -Wl,-T -Wl,UDPServer/UDPServer_linker_script.ld  -g    -I./microblaze_0/include/  -L./microblaze_0/lib/  \
 

In file included from UDPServer/udp.c:94:
./microblaze_0/include/lwip/sockets.h:214: error: redefinition of `struct timeval'

make: *** [UDPServer/executable.elf] Error 1

Done!

Yours sincerely,

Jian Rong

I have the HTTP web server working well under Freertos and the SAM7X.

My question; what is the correct way to add additional protocols (UDP) and
apps (TFTP), and additional HTTP connections

Should I create additional tasks using the FREERTOS calls for "xTaskCreate",

or create them using the "sys_thread_new" functions within sys_arch. This
will add an entry to the timeout table.



A point in the right direction will help

Thanks



Colin

When the tcp_pcb have been exhausted,will meet the problem listed below.
Assertion "tcp_input: active pcb->state != CLOSED" at line 170 in tcp_in.c
below code is locate in tcp_in.c lines 602
pcb->state = CLOSED;

There are the only reason which make assert "tcp_input: active
pcb->state != CLOSED".

Why assert here? or what's reason will lead to the assertion?

There are still anothe problem when the tcp_pcb have been exhausted:
I set TCP_MSG to 255, and when the tcp_pcb are exhausted, it will be
exhausted too.
once TCP_MSG have been exhausted,then TCP_MSG values would not be recovered.
What should I do now?
