Hi All.

May be I miss something but I do some searching and still can't understand.

 

Problem  configuration:

Orange Pi PC v 1.2 (try 3 different) 

fresh loaded  Armbian_5.90_Orangepipc_Ubuntu_xenial_default_3.4.113_desktop.img  (try different SD cards) 

any (try 3 different HP 2824, Zyxel Kinect, Cisco SRW2016)

 

If I plug my Orange Pi PC with this image to 1Gb  port I'v got blinking of lights and dmesg:

[  818.090335] PHY: gmac0-0:00 - Link is Down
[  819.090497] PHY: gmac0-0:00 - Link is Up - 100/Full
[  821.090494] PHY: gmac0-0:00 - Link is Down
[  822.090314] PHY: gmac0-0:00 - Link is Up - 100/Full
[  824.090335] PHY: gmac0-0:00 - Link is Down
[  825.090496] PHY: gmac0-0:00 - Link is Up - 100/Full
[  827.090502] PHY: gmac0-0:00 - Link is Down

 

I don't have this problem:

if I plug Orange PI PC into to 100Mb Ethernet port.

or

If I use some of 4.19 kernel based images (on 1Gb port also no problem) 

 

The problem still exists after apt-get update/ upgrade

 

So my question is: is it possible to solve this problem?

Probably.

 

But nobody will invest hours/days into a kernel that is just about to be trashed. Developers left supporting this kernel several years ago - we did only most urgent adaptations that its still working. We keep it only for its multimedia features which are absent in mainline. When this function will be brought up - expected soon / on 5.3.y - this kernel will be removed.

 

Use modern kernel.

So,  can I hope that on 5.3 armbian will support ov5640 csi cameras?

We have no resources for dealing with cameras ... but luckily kernel is a community project and someone might someday develop and support this feature. If you need this, hire some people and do it.

how about setting eth0 to 100mbit with ethtool and forget about autospeed-negotiation?
