Hello Team,

Finding difficult to configure ethernet as MII without RTOS in STM32H745I DISCOVER BOARD.
In command prompt when command PING IP address of board is entered every time it shows timeout. Find images enclosed. Kindly guide me. 

 

Best Regards,

In this article ethernet is configured with RTOS and I am trying without RTOS. But tried to follow the same steps, still unable to configure.

Hello @ggowd.1 

 

When not using FreeRTOS, the Ethernet interrupt should be disabled and MX_LWIP_Process should be called periodically (in main loop).

Hello @FBL 

 

Disabled ethernet interrupt and called MX_LWIP_Process periodically (in main loop) but "time out" and "Reply from 192.168.1.10: Destination host unreachable". error is displayed in command prompt. PFA of command prompt error.

@ggowd.1 Unfortunately only examples with FreeRTOS  are provided for this board. Try to build and run these (choose CM7 or CM4 as you need). At least, get to the state of working ping. Then try to "remove"  FreeRTOS.

With or without interrupt is not a principal question, even without RTOS you can use the ETH interrupt.
