STM32MP157-DK2 not connecting to ethernet

It seems to work, only when i have the cable plugged into the router.

Tried before to connect the board to 2 laptops without success...

How to configure eth0 to run ipv4 with dhcp enabled?

noticed /etc/network/interface file is missing

​Hello,

Did you visit the ST wiki page: https://wiki.st.com/stm32mpu/wiki/How_to_configure_ethernet_interface ?

It shows you how to configure eth0 /ipv4 with DHCP enabled.

Hello

i manually configured a ip, on the pc side dhcp is enabled.

After doing this, i still can't connect via ssh, not even ping ..,

Is it posible to disable ipv6? And how to doit?

Hi,

you said that via a Router all is correct with DHCP enabled, which is the correct behaviour. Did you try to disable DHCP using a p2p connexion?

I would recommend USB/Ethernet bridge for a P2P connexion. Just plug a USB TypeC cable to the OTG USB DK2 board and type ifconfig again, then manually assign this bridge to a static IP address :ifconfig <bridgename> 192.168.7.1 netmask 255.255.255.0 . Then you should be able to ping the board at 192.168.7.2,

Hello Oliver,

i tried the followings

• dhcp enabled on the PC side
• power up the DK2 board
• ethernet & usb otg cable connected
• ifconfig eth0 192.168.7.22 netmask 255.255.255.0
• on the pc when ping 192.168.7.22 i get time out response

tried the same with the usb otg connection, and get ping timeout

To be honest its my first approach with a linux embedded system, didn't thought to be such challenging to do a network connection.

​Hello Anton,

Make sure the DK2 board boot pins are set so that you could see a demo on target display screen.

With the Ethernet/USB bridge (using USB type C cable), you should have the following network setup (or similar) from the host side and board side. I've highlighted the bridge which appears when you plug the USB Type C cable.  I run linux on a Linux VM on Windows 10.

Hello Oliver,

thanks for your patience,

i finally managed to establish a ssh connection between my pc and the dk2 board trough USB-C connection.

I setup 192.168.7.1 static ip for my usb network connection on the PC side.

Then i was able to ping 192.168.7.2 board, also ssh worked via putty.
