Hi,
I am trying to setup my W5100 module in server mode. I have done the necessary settings, like configuring the GAR, SHAR etc).
I am able to ping the W5100 and after the OPEN command the socket status register’s value is 0x13.
But I am not able to set the listen command.
After executing the listen command the socket status register does not give 0x14.
The status of my Link Leds are
Green Led = Constant ON with no blinking.
Orange Led = blinking
Hi,
If my code looks Ok, then how can I debug this issues?
Do I need to check something on my desktop side?
If yes then how?
Are there any tools which can help in debugging this issues?
So, I recommend to use case(1) or debug with changing return value(2).
switch(getSn_SR(s)) // check SOCKET status
{ // ------------
case SOCK_ESTABLISHED: // ESTABLISHED?
if(getSn_IR(s) & Sn_IR_CON) // check Sn_IR_CON bit
{
printf("%d : Connect OK\r\n",s);
setSn_IR(s,Sn_IR_CON); // clear Sn_IR_CON
}
if((len=getSn_RX_RSR(s)) > 0) // check the size of received data
{
len = recv(s,buf,len); // recv
if(len !=send(s,buf,len)) // send
{
printf("%d : Send Fail.len=%d\r\n",s,len);
}
}
break;
// ---------------
case SOCK_CLOSE_WAIT: // PASSIVE CLOSED
disconnect(s); // disconnect
break;
// --------------
case SOCK_CLOSED: // CLOSED
close(s); // close the SOCKET
socket(s,Sn_MR_TCP,port,mode); // open the SOCKET
break;
// ------------------------------
case SOCK_INIT: // The SOCKET opened with TCP mode
listen(s); // listen to any connection request from "TCP CLIENT"
printf("%d : LOOPBACK_TCPS(%d) Started.\r\n",s,port);
break;
default:
break;
}
i.e. check status is SOCK_INIT then command listen.
In your while, return value is always 1 if listen is failed. So change return value and then debug what is problem, status is not SOCK_INIT or status is SOCK_INIT but listen command is failed.
Hi,
I don’t know why you use in ISR routine for receiving data.
Normally, ISR is the faster, the better.
Anyway, You’d better modify your code - reset delay and while(temp) statement block .
I recommend that…
uint32_t initWiznet(void)
{
//unsigned char MAC_ADDR[6];
uint8_t status = 0x01;
/* Power the wiznet chip */
GPIO_PinOutSet (gpioPortC, 1);
Delay_ms(1);
/* Reset the wiznet chip */
ASSERT_WIZNET_RESET();
Delay_ms(1);
init_usart0_for_wiznet();
DEASSERT_WIZNET_RESET();
Delay_ms(10); //<-- Reset time is over 10ms. Inserted by M.C
setRTR(6000); /* Retry time = 600 ms*/
//Delay_ms(1); // No needed
setRCR(3); /* Retry count = 3 */
//Delay_ms(1); // No needed
//setIMR(0x00); /* Interrupt mask */
setGAR(); /* Gateway IP address */
//Delay_ms(1); // No needed
setSUBR(); /* Subnet mask */
//Delay_ms(1); // No needed
setSHAR(); /* MAC address */
//Delay_ms(1); // No needed
setSIPR(); /* Source IP address */
//Delay_ms(1); // No needed
SysInit(0x55, 0x55); /* TX = 8kB, RX = 8 kB */
//Delay_ms(1); // No needed
setIMR(IR_SOCK(0)); /* Enable the socket 0 interrupt */
//Delay_ms(1); // No needed
/* Configure the EFM32 for external interrupt from Wiznet chip */
NVIC_ClearPendingIRQ(GPIO_ODD_IRQn);
NVIC_EnableIRQ(GPIO_ODD_IRQn);
/* Configure PE13 as input */
GPIO_PinModeSet(gpioPortE, 13, gpioModeInput, 1);
/* Set falling edge interrupt */
GPIO_IntConfig(gpioPortE, 13, false, true, true);
write_wiznet_reg(Sn_IR(0), 0xff);
/* Open the socket for server mode */
temp = 1;
/* The below code is for testing purpose only
* It checks if :listen command is properly set.
* Else it loops forever.
*/
while(temp)
{
temp = getSn_SR(0);
switch(temp)
{
case SOCK_ESTABLISHED:
// printf("socket connected!!!");
// check S0_IR(CONNECTED) = '1'
// check S0_IR(RECV) or getSn_RX_RSR(0) > 0
// If yes, receive data
break;
case SOCK_LISTEN:
// wait for connection
break;
case SOCK_INIT:
listen(0);
break;
case SOCK_CLOSE_WAIT:
// check S0_IR(RECV) or getSn_RX_RSR(0) > 0)
// if yes, receive data
// close 0 socket ( close(0) or disconnect(0) )
break;
case SOCK_CLOSED:
socket(0, Sn_MR_TCP, 80, 0x00);
break;
default:
break;
}
}
/* Refer to GPIO_ODD_IRQHandler() for further packet processing
* Once connection has been establised, TCP packet processing
* will be carried out based on external interrupt on PE13
*/
return status;
}
Hi,
Thanks for your replies.
The issues did seem to be with the delay.
I added delay in the wiznet read function and made it same like the wiznet write function.
The issue is resolved now.
Thanks once again for your help!
At the moment I am running into exactly the same issue with the W5100. I understand you solved it with a delay in the read function? I do not understand where that is since the W5100 first has to go into LISTEN mode before anything can be read…
