You can also use non-thread safe functions in your lwIPInit(), this is always better than using heavyweight pppapi_ calls. >>( void ) pvArgument; >>SysConfigGetLocalIPAddress(&ipAddr1, &ipAddr2, &ipAddr3, &ipAddr4); >>// Set up the network interface. >ip_addr_set_zero( &xGateway ); >ip_addr_set_zero( &xIPAddr ); >ip_addr_set_zero( &xNetMask ); >>LWIP_PORT_INIT_GW(&xGateway); >LWIP_PORT_INIT_IPADDR(&xIPAddr); >LWIP_PORT_INIT_NETMASK(&xNetMask); >>netif_set_default( netif_add( &xNetIf, &xIPAddr, &xNetMask, &xGateway, >NULL,GSM_init, tcpip_input ) );//ethernetif_init >netif_set_up( &xNetIf ); xNetIf is not your PPPoS interface, the PPP code you are using is still using an internal netif. Note that master HEAD is now using a user provided netif for PPP, which should prevent the confusion you are having. Sejarah Islam Di Minangkabau Pdf Printer.
