Hello!

I have a board based on STM32F Ethernet PHY: KSZ8721BL; LwIp 1.3.2. I took [url = ''http://electronix.ru/redirect.php?http://www.st.com/internet/com/SOFTWARE_RESOURCES/SW_COMPONENT/FIRMWARE/stm32f2x7_eth_lwip.zip'']this[/url] example of LwIp for STM32F2*7 and changed ethernet driver configuration for my board (change are highlighted): stm32f2x7_eth_bsp.c

system_stm32f2xx.c: 

uint32_t SystemCoreClock = 100000000;

The board started working with this code successfully. After 2-4 hour the board ceased to answer. Interesting fact: At the start of pinging the responce time <= 1 ms. After some time (always random period) pinging changes to 400-2000ms. If I start pinging on a second computer with option -f(flood), pings to board will change to 1-40ms. After stop pinging on the second computer the responce time returns to 400-2000ms again. Somebody met this problem? Regards, Rayne. #lwip-freertos-stm32f2-ping

Hello,

Is your application based on FreeRTOS or standalone?

hello,

Try to modify ethernetif_input function as below:

void ethernetif_input(void * pvParameters)

{

  struct pbuf *p;

  for( ;; )

  {

    if(xSemaphoreTake(s_xSemaphore, emacBLOCK_TIME_WAITING_FOR_INPUT)==pdTRUE)

    {

GET_NEXT_FRAGMENT:

      p = low_level_input( s_pxNetIf );

      if (p != NULL)

      {

        if (ERR_OK != s_pxNetIf->input( p, s_pxNetIf))

        {

          pbuf_free(p);

          p=NULL;

        }

        else

        {

          xSemaphoreTake(s_xSemaphore, 0);

          goto GET_NEXT_FRAGMENT;

        }

      }

    }

  }

}

Work! Thanks!

But I catch next bug: HF on static void

tcpip_thread(void *arg) in call function:

[code]

#if LWIP_ARP

     if (msg->msg.inp.netif->flags & NETIF_FLAG_ETHARP)

{

       ethernet_input(msg->msg.inp.p, msg->msg.inp.netif);

     } 

[/code]

Addr of msg->msg.inp.p = 0x23 => CPU hardfault.
