MHD Posted June 24, 2019 Share Posted June 24, 2019 I need help please, I am working on NanoPCt3 board based on Armbian_5.83_Nanopct3plus_Ubuntu_bionic_next_4.14.115_desktop I put static ip to eth0 and when i try to ping the output in not stable: 64 bytes from 104.27.115.15 (104.27.115.15): icmp_seq=1 ttl=58 time=580 ms 64 bytes from 104.27.115.15 (104.27.115.15): icmp_seq=2 ttl=58 time=120 ms 64 bytes from 104.27.115.15 (104.27.115.15): icmp_seq=3 ttl=58 time=350 ms and then the output: Destination host unreachable. Destination host unreachable. Destination host unreachable. and i think there are some issues in kernel drivers related on Ethernet or ipv4 so could you please help me to fix Ethernet issue ??

Have you ruled out other things? Try also older kernel versions -> armbian-config -> system if that change anything. Link to comment Share on other sites More sharing options...

Thank you for replay, I try armbian-config -> system -> switch to other kernels then asked me to confirm and finally returned to system list without any action !!

Igor Posted June 25, 2019 Share Posted June 25, 2019 Try to update and upgrade system before trying that. You have unchanged system? Link to comment Share on other sites More sharing options...

MHD Posted June 25, 2019 Author Share Posted June 25, 2019 Mr. I have two boards (one with s5p6818-debian-wifiap-sd8g-20171102, and another with Armbian_5.83_Nanopct3plus_Ubuntu_bionic_next_4.14.115_desktop), I do the same experiment: 1- Apply static ip in /etc/network/interfaces like: source /etc/network/interfaces.d/*# Network is managed by Network managerauto lo iface lo inet loopback auto eth0 iface eth0 inet static address 10.1.1.125 netmask 255.255.255.0 network 10.1.1.0 2- Update and upgrade packages from terminal. 3- Apply static ip ethernet on my computer 10.1.1.2 4- Finally: Test connection from board terminal: ping 10.1.1.2 so the output and performance are very different between tow boards: Armbian (there are problems): I've attached the terminal log. Debian (without any problems): debian ping output: 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=1 ttl=58 time=1.52 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=2 ttl=58 time=0.950 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=3 ttl=58 time=1.86 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=3 ttl=58 time=1.54 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=3 ttl=58 time=1.51 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=3 ttl=58 time=1.55 ms 64 bytes from 10.1.1.2 (104.27.115.15): icmp_seq=3 ttl=58 time=1.45 ms So where is the problem? I tried a lot of things without any progress ,thanks in advance. Link to comment Share on other sites More sharing options...
Igor Posted June 25, 2019 Share Posted June 25, 2019 We need refference to our older builds since I dont recall such troubles. Stock FA image is completly different. Different uboot and kernel. OS / userland usually doesnt play any role in such troubles.Wrote on mobile Link to comment Share on other sites More sharing options...
