Hi Jens,
thank you for your colaboration. Is it possible that you share if me your
fix? I am trying not to reinvent the wheel.
As I said to Simon, I am trying to use the LWIP_NETIF_LINK_CALLBACK
and LWIP_NETIF_STATUS_CALLBACK functions to keep track of the Phy Link, but
these functions never gets called, even if I disconnect the cable.
My demicode is as below:
*#if LWIP_NETIF_STATUS_CALLBACK*
*void status_callback(void) {*
* LED_BLUE_TOGGLE();*
*}*
*#endif /* LWIP_NETIF_STATUS_CALLBACK */*
*#if LWIP_NETIF_LINK_CALLBACK*
*void link_callback(void) {*
* if (netif_is_link_up(&fsl_netif0)) { //DES link up blink fast*
* LED_GREEN_ON();*
* dhcp_start(&fsl_netif0);*
* netif_set_up(&fsl_netif0);*
* } else {*
* LED_GREEN_OFF();*
* dhcp_stop(&fsl_netif0);*
* netif_set_down(&fsl_netif0);*
* }*
*}*
*#endif /* LWIP_NETIF_LINK_CALLBACK */*
-------------------------------------------------------------------
* PRINTF("TCP/IP initializing...\r\n");*
* tcpip_init(NULL, NULL);*
* PRINTF("TCP/IP initialized.\r\n");*
* xSemaphoreENET = xSemaphoreCreateBinary();*
* while (netif_add(&fsl_netif0, &fsl_netif0_ipaddr, &fsl_netif0_netmask,*
* &fsl_netif0_gw,*
* NULL, ethernetif_init, tcpip_input) == NULL) {*
* netif_remove(&fsl_netif0);*
* vTaskDelay(1000 / portTICK_PERIOD_MS);*
* }*
* WDOG_Refresh(WDOG);*
* netif_set_default(&fsl_netif0);*
* netif_set_up(&fsl_netif0);*
*#if LWIP_NETIF_STATUS_CALLBACK*
* netif_set_status_callback(&fsl_netif0, status_callback);*
*#endif /* LWIP_NETIF_STATUS_CALLBACK */*
*#if LWIP_NETIF_LINK_CALLBACK*
* netif_set_link_callback(&fsl_netif0, link_callback);*
*#endif /* LWIP_NETIF_LINK_CALLBACK */*
* err = dhcp_start(&fsl_netif0);*
