Hi,
I never worked with netcon. Almost all the modules I have written are in RAW
mode.
Just now I made the first module with Sockets.
I suggest running something much simpler like the echo server to start with.
Can you ping to the board ?... If you can try running ping -t and see if it
runs for
some time.
BR,
Noam.

Subject: [lwip-users] netconn http server memory problem ?
Hello
I recently managed to compile and run lwip+FreeRTOS on stm32f107. I can ping my
device now.
I took st example netconn httpserver and put in my project it compiled. But i
cant reach http page. Connection keep resetting (wireshark show it yellow
highlight). I tracked down my problem
accept_function in api_msg.c calls netconn_alloc newconn equals NULL
in netcon_alloc
if (sys_mbox_new(&conn->recvmbox, size) != ERR_OK) {
sys_sem_free(&conn->op_completed);
goto free_and_return;
}
sys_mbox_new doesnt equal ERR_OK
in sys_mbox_new *pxMailBox = xQueueCreate( iSize, sizeof( void * ) ); returns
NULL
it seems like memory problem so I make adjusments and make
#define configTOTAL_HEAP_SIZE ((size_t) (32 * 1024)) in
FreeRTOS_config.h
and
#define MEM_SIZE (10*1024) in lwipopts.h
I played with values hoping to make it right but no luck
I tried heap_1.c throgh heap_4.c didnt work (accept heap_3.c but after
connection all my threads stopped)
I think problem is somewhere else but couldn't figure out.
Thank you
