Hello experts, what am I doing wrong? For days I have been trying to put the LAN interface of my STM32H743ZI board into operation. I just want to send a text to my PC and also be able to receive text from the PC. The board should be the server. Unfortunately I could not find a working example. Also the sample project
doesn't work. In contrast to the example, however, I could not set the “Ethernet interrupt preemption priority�? to 5 because the value cannot be changed in CUBEMX. Furthermore, I did not select “MII�?, but “RMII�?, because according to the manual for this board, the “RMII�? interface is correct.
The project starts without an error message, but the debugger stops when calling
„MX_LWIP_Init“
at the point
/* Registers the default network interface */
netif_set_default(&gnetif);
I have chosen the following LAN settings:
STM32H743 Board IP-Adress: 192.168.133.53
Router IP-Adress: 192.168.128.1
IP-Adress from PC’s: 192.168.130.5
Sub-NET Mask: 255.255.248.0
Port: 23
The orange control lamp on the Lan port flashes quickly. However, when I send a ping from the PC, I don't get a response from the board.
I have attached the complete CubeIDE project as an attachment.
Can someone help me??? (The solution can also be without freertos)
I am desperate!
Best regards, Holger

netif_set_up(&gnetif);
}
else

netif_set_down(&gnetif);
}
/* Set the link callback function, this function is called on change of link status*/
// netif_set_link_callback(&gnetif, ethernet_link_status_updated);

/* USER CODE BEGIN 3 */
/* USER CODE END 3 */
}Cube MX Settings:
UPDATE:
The Ethernet interrupt preemption priority can be changed in the NVIC settings.
After changing the value to 5, the for (;;;) {... } loop is processed.
/* Infinite loop */
for(;;)
{
for (;;) {
osDelay(10);
udp_buffer = pbuf_alloc(PBUF_TRANSPORT, strlen(message), PBUF_RAM);
if (udp_buffer != NULL) {
memcpy(udp_buffer->payload, message, strlen(message));
udp_send(my_udp, udp_buffer);
pbuf_free(udp_buffer);
}
}
}But the STM32 still does not answer when I send a ping from the PC. The STM32 also does not send the message to the PC.
