Nanopct3+ Ethernet issue


MHD

Question

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 ??

So far we haven't notice any. Have you ruled out other things? Try also older kernel versions -> armbian-config -> system if that change anything.

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 !!

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 manager
auto 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.

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.

Absolutely no network problems.
