STM32H745 Pinging

Hello everyone,

 

I am trying to establish a connection between my STM32H745I(Discovery kit) and my computer and the jumpers are set to STLK for programming, and I also have connected the board through LAN to my computer directly. I have set my computer IP static to 192.168.4.26 and I set the IP for the STM32H745 to 192.168.4.187 through LWIP settings(by disabling DHCP and set the static IP), but I cannot ping the STM32 from my computer(always I receive "From 192.168.4.26 icmp_seq=1 Destination Host Unreachable"). Ethernet port on the STM32 has green and orange LEDs on, on the both sides of the port.

 

I have attached screenshots from my ETH and LWIP settings, and if more information is needed to debug the problem, I would be happy to share it!

I would be grateful for your guidance, since it is my first ever project with STM32. Thanks in advance!

    Hello @Mahyarshall,

    I don't see any apparent issue with your configuration. Please ensure that the call to MX_LWIP_Process() is in the while loop.

    However, just a heads up, you can maybe turn the wired connection on and off on your PC to make it work properly.

    With Regards,
