I set that str912 is server. and pc is client. After program start, data receive and send for 8 times. It's ok. But 9th data didn't receive and send. Why do you above circustance?
RE: it didn't run after data receive 8 times Posted by Richard on March 10, 2010 If you have written your own client/server program, then I'm afraid only you will be able to debug it, unless you can provide a lot more information and code and find somebody willing to spend the time to look at it.
Regards.
RE: it didn't run after data receive 8 times Posted by telkim on March 11, 2010 Thank for reading a message. I use freertos version 5.0.2
target board program following code for server
1. calling founction
void vBasicWEBServer( void *pvParameters ) // basicweb.c { unsigned char pcMessageToExchange[] = "\n init socket\r\n";
struct ip_addr xIpAddr, xNetMast, xGateway; extern err_t ethernetif_init( struct netif *netif );
/* Parameters are not used - suppress compiler error. */ ( void ) pvParameters;
/* Create and configure the EMAC interface. */ IP4_ADDR( &xIpAddr, emacIPADDR0, emacIPADDR1, emacIPADDR2, emacIPADDR3 ); IP4_ADDR( &xNetMast, emacNET_MASK0, emacNET_MASK1, emacNET_MASK2, emacNET_MASK3 ); IP4_ADDR( &xGateway, emacGATEWAY_ADDR0, emacGATEWAY_ADDR1, emacGATEWAY_ADDR2, emacGATEWAY_ADDR3 ); netif_add( &EMAC_if, &xIpAddr, &xNetMast, &xGateway, NULL, ethernetif_init, tcpip_input );
/* make it the default interface */ netif_set_default( &EMAC_if );
/* bring it up */ netif_set_up(&EMAC_if);
vSerialPutString( 0, pcMessageToExchange, strlen( pcMessageToExchange ) ); /* Initialize HTTP */ // httpd_init(); //kcs kcs_server(); // kcs
/* Nothing else to do. No point hanging around. */ vTaskDelete( NULL ); }
void kcs_server() // httpd.c { struct tcp_pcb *pcb; pcb = tcp_new(); tcp_bind(pcb, IP_ADDR_ANY,2000); tcp_arg(pcb,NULL); pcb = tcp_listen(pcb); tcp_accept( pcb, helloworld_accept); }
void helloworld_accept( void *arg, struct tcp_pcb *pcb, err_t err) // kcs { int i,j;
vSerialPutString( 0, "accept\r\n", 10 ); vSerialPutString( 0, "read\r\n", 8 ); tcp_err(pcb,conn_err); // 2010.3.4 kim tcp_recv(pcb, kcs_receive); for(j = 0; j < 1; j++) { vSerialPutString( 0, "write\r\n", 9 ); tcp_write(pcb, GREETING, strlen(GREETING),1); for( i = 0; i < 100;i++) ; }
}
err_t kcs_receive(void *arg, struct tcp_pcb *pcb, struct pbuf *p, err_t err) // kcs { int i; vSerialPutString( 0, "receive\r\n", 11); if( p != NULL) { tcp_recved(pcb,p->tot_len); // add kcs 2010.3.4 vSerialPutString( 0, p->payload, p->tot_len ); err = tcp_write(pcb,p->payload,p->tot_len ,1); } else if( err == ERR_OK) { vSerialPutString( 0, "socket close\r\n", 16 ); tcp_close(pcb); } err = tcp_write(pcb,p->payload,p->len,1); }
Above code run 8 times packet and ping reply, but don't run 9 times. and ping don't reply why did it run?
RE: it didn't run after data receive 8 times Posted by telkim on March 26, 2010 addtion I used lwip code. Above code rewrite web server code.
