Ethernet is not available on NUCLEO-H753ZI (using Keil RTX5)

nito 3 months ago

I cannot connect Ethernet in Keil µVision V5.42 and NUCLEO-H753ZI.

There is no response for ARP or Ping.

How do I connect NUCLEO-H753ZI to a PC via Ethernet in Keil RTX5?

Have I forgotten to configure something?

This environment is as follows.

Board : NUCLEO-H753ZI (CPU:STM32H753ZI)

IDE : µVision V5.42.0.0

Compiler : ARM Compiler v6

RTOS : Keil RTX5

Others : STM32CubeMX Ver.6.15.0

I have done as follows:

1. µVision Pack Install

ARM::CMSIS ver.6.2.0

ARM::CMSIS-Driver ver.2.10.0

11. Add code in Main.c

Add Includes

/* Private includes ----------------------------------------------------------*/
/* USER CODE BEGIN Includes */
#include "cmsis_os2.h"
#include "rl_net.h"
/* USER CODE END Includes */

Add USER CODE 2

/* Initialize all configured peripherals */
MX_GPIO_Init();
MX_ETH_Init();

/* USER CODE BEGIN 2 */
SystemCoreClockUpdate();

osKernelInitialize();

netInitialize();

osKernelStart();
/* USER CODE END 2 */

12. Setup Windows PC

ip address 192.168.0.10, mask 255.255.255.0, gateway {empty}

In this environment, when I send "arp -a" or "ping 192.168.0.100" from a Windows PC, I get no response...
