Hello, I have just updated to the latest Debian Server image of NanoPI NEO 2. When connecting via Serial and using vim.basic/tiny I got the following strange behaviour: As soon as I enter the insert mode a newline is inserted automatically. This does not happen when connecting via SSH. So far I haven't experienced this behaviour with my previous image. Any ideas? Kind regards, Markus NB: textwidth is set to 0 (disabled).

Wow. I have tested now on two different Nanopi NEO2 with two different cables. And you have been right, it was the cable. Unbelievable. Thanks for your hints.

Thanks for reponse and your links. I have just read thru them. There is one note ( see below ) I don't know how to check if this paramter is set correctly on Nanopi NEO2. But anyway as proposed I will do some thorough testing as proposed by you.

Just tested with another Ethernet cable. Problem is still there: /var/log/armhwinfo.log has been uploaded to http://sprunge.us/QQKP My understanding is that actually Nanopi NEO2 is different from most of the other variants because it uses this Gigabit Ethernet chip RTL8211E-VB-CG. Do you think this makes a difference with respect to this issue? My next step is to test this issue on another Nanopi NEO2 this evening.

Right now only one. But tomorrow I will try another one. I will keep you posted :-)

Thanks for checking. It doesn’t look like a hardware issue because it only happens if I run the iperf in downstream ( iMac > Nanopi ) mode. If I run iperf in upstream mode ( Nanopi > iMac ) the connection is absolutely stable ( no disconnect ). I think it’s a driver issue because of the huge amount of data transmitted. Do you know a mailing list I can address this issue to?

Hi everybody, I would like to use the Nanopi NEO2 as firewall and therefore would like to support testing ethernet. I setup an iperf server on Nanopi NEO2 and I am running the client on my iMac to test stability of ethernet connections. After around 30-40 seconds the ethernet links goes down and is coming up back again.
