Greetings !
I am using Azure RTOS on STM32H743 and I tried setting up the Static IP for Ethernet. I could successfully able to assign Static IP .
Here after this I am observing that , most of the times IP address is assigning only when I remove and re-insert the Network Cable .
Can you please help me out to overcome this issue . Below mentioned is my "App_Link_Thread_Entry" function .
Thanks in Advance

/* @brief Link thread entry
* @param thread_input: ULONG thread parameter
* @retval none
*/
static VOID App_Link_Thread_Entry(ULONG thread_input)
{
ULONG actual_status;
UINT linkdown = 0, status;
while(1)
{
/* Get Physical Link stackavailtus. */
status = nx_ip_interface_status_check(&IpInstance, 0, NX_IP_LINK_ENABLED, &actual_status, 10);
if(status == NX_SUCCESS)
{
if(linkdown == 1)
{
linkdown = 0;
status = nx_ip_interface_status_check(&IpInstance, 0, NX_IP_ADDRESS_RESOLVED,
&actual_status, 10);
if(status == NX_SUCCESS)
{
/* The network cable is connected again. */
printf("The network cable is connected again.\n\r");
/* Print UDP Echo Client is available again. */
printf("Webserver Application is available again.\n\r");
//#if 0
// WWDebug: try this:
/* Send command to Enable Nx driver. */
printf("\r\n WWDebug : Try to re-enable link\n\r");
nx_ip_driver_direct_command(&IpInstance, NX_LINK_ENABLE, &actual_status);
tx_semaphore_put(&Semaphore);
//#endif
}
else
{
/* The network cable is connected. */
printf("The network cable is connected.\n\r");
/* Send command to Enable Nx driver. */
nx_ip_driver_direct_command(&IpInstance, NX_LINK_ENABLE, &actual_status);
tx_semaphore_put(&Semaphore);
}
}
}
else
{
if(0 == linkdown)
{
linkdown = 1;
/* The network cable is not connected. */
printf("The network cable is not connected.\n\r");
}
}
tx_thread_sleep(60);
}
}
/* USER CODE END 1 */

Hello @PG.9 ,
Please have a look at this article: How to create project for STM32H7 with Ethernet and LwIP stack working.
Make sure to disable DHCP server.
You can check the available application within STM32CubeH7 MCU package.

Hi @PG.9 ,
In order to understand well your issue, could you please clarify some points :
- when you say "you are able to assign Static IP", you mean that your IP instance address is affected than go to 0 ?
- Your IP instance address is affected only when you unplug and plug the cable ?
- Without unplug and plug the cable, are you able to ping the board ?
- Is your issue present even with default App_Link_Thread_Entry without any modification ?
