Question Regarding Networking Middleware for Ethernet interface

Hi, first, you should start a simple Network program.

1)Did you run RTOS in your mentioned code? Before netInitialize (); you should start RTOS for the OS can handle the network PHY.

2)Please disable DHCP and set a static IP to check the ping command. via   Net_Config_ETH_0.h file.

3)Disable all configuration network settings that you have set by netIP_aton  and netIF_SetOption.

Something like this:

__NO_RETURN static void app_main (void *argument){	
 int32_t Socket;
	
	netInitialize();
	
		Socket = netUDP_GetSocket (udp_cb_func);
			
		if (Socket>= 0) 
		{
		netUDP_Open(Socket,54321);
							
		}

		
		while(1)
		{

			
		}
	
}
int main (void){

  osKernelInitialize();                 // Initialize CMSIS-RTOS
  osThreadNew(app_main, NULL, NULL);    // Create application main thread
  osKernelStart(); 
	
	while(1);
}

  osThreadNew(app_main, NULL, NULL);    // Create application main thread
  osKernelStart(); 
	
	while(1);
}

My collegs want to have a solution without RTOS. Is it possible to get running without RTOS usage?

Please read this page:www.keil.com/.../nw_resource_requirements.html

That means that we should apply RTOS functionality and thus we can not use that - meanly due to memory fragmentation.

Hi again,

You can use old version of Network( I don't recommend) or use LWIP.
