Banana Pi M3 crashes if ETH plugged

[bahtiyar57]

I've no problem using my Banana Pi with a wifi connection.

But if I plug it on my router with a ethernet cable it crashs after a short time.

Should I upload the output of armbianmonitor when ETH is plugged?
Because it will take me a few tries, to do that.

Better method would probably be using debug serial console to grab the output while the crash happens.

I have a feeling that this is same as 

 Not 100% sure though.

I bought a Uart cable  but Im afraid of plug it to my sbc

Is there an other option?

Or can you help me to use it without destroying anything?

Boot the system in the case when it is stable, i.e. with wi-fi.
Look at the system logs and post the one when the Ethernet connection failed.

I have a question. If it works well, why switch to another interface (Ethernet)?

 

This device does not have a battery-powered clock and it requires the Internet

to get an accurate time stamp from the time server and set the SOC's internal clock in real time.

 

You have disabled WI-FI and connected Ethernet.
Do the settings in the connection management system look correct now?
Is the network cable working?
Does the banana receive the DHCP settings from the router?

Did the router have Internet access at the time of banana connection?

You didn't write anything about it.

Just for reference.

There has been a strong magnetic storm on our planet for the last two days.

My Internet went down several times for one hour or more.

I want to switch to Ethernet because its faster.

 

The Ethernet Connection don't fails. It will connect. And I can connect via SSH. But after a short time the Board shuts down.

If you downloaded a banana from the SD card and a failure occurred,

simply turn off the device, take out the SD card and connect it to a Linux computer via the adapter.

Find the latest system logs and review them.

This is the jumper on the device.
I use this scheme. Everyone uses this scheme. It's safe.

Thank you. I undestand that. What I have to do after I plugged the serial console in.
I know I have to use Putty in Windows and configure the seria line to 115200.

And then?

 

EDIT:
Maybe I'm wrong, but I think it's a voltage problem.

[Gunjan Gupta]

just look at the output and share the same here especially close to the moment the board crashes

[bahtiyar57]

This is very complicated for me. Because I don't know how I have to do it exactly?
I used a time a very old Easy-Box 802. And with this it didn't crashed.

With my FritzBox 7490 and 7520 it will crash.

Know I will try to disable EEE (Energy Efficient Ethernet) on my Router.

I read that some peolpe had problems with this. But they diabled it with adding:

dtparam=eee=off

to /boot/config.txt

Or by running this command:

ethtool --set-eee eth0 eee off

 

[bahtiyar57]

Disabling EEE on my router settings solved the problem.

 

 

EDIT:

Is there an option to disable EEE directly from Armbain?
