@drewmoseley Help me pls. I can’t ping 8.8.8.8. I only can ping localhost I have imx7d-pico (thud 2.6) Yocto, based on this tutorial: Technexion PICO-PI-IMX7 [not ping]

@dellgreen I can ping loopback and root@imx7d-pico:/etc/sysctl.d# pwd /etc/sysctl.d root@imx7d-pico:/etc/sysctl.d# ls 99-sysctl.conf https://gist.github.com/neuberfran/1409a1dfbd49abbfa7c4ee56061c478f 99-sysctl.conf # This configuration file is taken from Debian. # # /etc/sysctl.conf …

Am out of the office at the moment to look into further. But also to remove all other sources of problem. Connect your laptop and boards ethernet together directly without any router/ switch. Set the static IP address of each to be on the same network. 192.168.0.1 and 192.168.0.2. same subnet mask…

@dellgreen tks. I tried with ethernet crossover cable and with normal ethernet cable. The results were the same and with issue: [screenissue]

ok thats good, its narrowed down the problem. I also see from all your screengrabs of the imx7d-pico that your are transmitting and receiving packet via the eth0 interface (see RX,TX), which is good. Do you have strict firewall rules running on the pico (i.e by using iptables, firewalld) that are b…

@dellgreen iptables and firewalld not exists [FirewalldAndIptablesNot]

sorry, but I’m all out of ideas now. I would recommend getting onto the vendors board support forum for your device to see if any other users of the board have experienced the same issue.

@dellgreen tomorrow I will reinstall this: https://github.com/TechNexion/edm-yocto-bsp/issues/7 in my other board (with multi touch) and I will be able to analyze, in detail, if the ethernet works and what settings it may be using.

Yeah, that’s a good troubleshooting step. I always try to maintain a build without Mender integrated to use as a testing step. Good luck. Drew

@dellgreen @drewmoseley Works in Yocto 2.0 by technexion using interfaces file and not systemd.networkd: root@pico-imx7:~# cat /etc/network/interfaces auto lo iface lo inet loopback iface wlan0 inet dhcp wireless_mode managed wireless_essid any wpa-driver wext wpa-conf /etc/wpa_supplicant.co…

that good news, given that is a totally different image, i would guess the problem was caused by how the previous image was put together. I would be less likely to be a systemd-networkd issue given how heavily and widespread it is used. Does technexion have newer yocto versions to test as 2.0 is en…
