Hello

I am using Nucelo 144 STM32F207 based board and running Netcom Application using keil version 5.

Problem 1:-

sometimes while serving a page it hangs and need a restart.

on debugging i found oot it is stuck in following

void vTaskSwitchContext( void )

{

if( uxSchedulerSuspended != ( UBaseType_t ) pdFALSE )

{

/* The scheduler is currently suspended - do not allow a context

switch. */

xYieldPending = pdTRUE;

}

Seems like the task switching is suspended.

observing the IP traffic on wireshark it seems PC is still in touch with the stm32f207

Problem 2 :-

sometimes connection is made and is closed without allowing any thing

I use Hercules tool( in client mode) from HW Group company to connect to board

Regards,

KS

Hello,

I suggest, as a first step, to run one of the LwIP example available in

package with a similar type of your project.

You can use the example code provided and compare the code/functions inputs and outputs with yours.

STM32F207ZG-Nucleo\Applications\LwIP\LwIP_HTTP_Server_Netconn_RTOS

You can have a look to this manual

: â€œDeveloping applications on STM32Cube with LwIP TCP/IP stackâ€�.
