K64F: RTOS + LiWP - tcp echo and http server

[grochal7]

Hello!

Is it possible to deinitialize the tcpip with liwp?

I'am using the tcp echo example.

I'd like to close tcp taks and then open the http server (also from http server example) - after pressing the button.

So first i initialized tcpecho and switch IRQ. It works. Then I press the button - now i'd like to initialize http server.

If i try use both in one project (http server initialization after pressing a button), I have this statement:

"tcp_slowtmr: active pcb->state != CLOSED".

Now I try to delete tcp connection and tcp task:

netconn_close(conn);
netconn_delete(conn);
vTaskDelete(xHandle_TCP_task);‍‍‍‍‍‍‍‍‍

And after that initialize the http server:

if(xTaskCreate(http_server,"http_server",5000, NULL, 16, NULL) != pdPASS)
{
     PRINTF("Task creation failed!(main)\r\n");
}
‍‍‍‍

Now I dont have "tcp_slowtmr: active pcb->state != CLOSED", but unfortunately, still not working.

Both of exampkes work separately.

So, what i should to do? Is it possible to use http server after closing some tcpip application?

Can anyone please confirm for me that the recently updated EthernetInterface library works on the FRDM-K64F platform? I am presently struggling to get the TCPSocket_Helloworld example application to run. It hangs when init() is called.

I'm using SDK 2.3.0 for my k64f board and all of examples (with freertos and without) from this SDK work (SDK 2.2.0 works too)

Whitch one not working for u?

Hi grochal7:

It is possible to run tcp echo and http server simultaneously.

I added function tcpecho_init based http server demo. Please see below picture. Both echo server and http server work normally.

But deinitialize the tcpip is not a normal behavior.  On most embedded system, when you start the TCP/IP stack, you never stop it. A lot of the memory that LwIP uses comes from statically allocated pools.
