Welcome to this forum! I don’t really know what you’re doing wrong, because it should working (Debian 10 Buster with kernel 5.1.1 I guess? This one: BPI-M1/M1/R1 new image:Debian 10 buster mate desktop with grub support (boot-2019.07 + kernel 5.1.1))
I can think of 2 things:
- Board has failed
- Maybe you’re doing wrong at the network configuration.
But I’ve tested Armbian Buster and created a new image. It’s stable last night, so you can give it a try. Just use one port for DHCP, doesn’t matter which.
The image is posted here: 2020-04-21: Armbian Buster (4.19.62-sunxi) Preview/Test-image - Lamobo/Banana Pi R1
That’s working (default configuration), because it’s running of mine. Then you can test if it are the ports that has failed or some other problem.
Oh! And by the way! Maybe you need to be more specific, such as:
- Which image are you using exactly? Because there are more Debian 10-based distro’s around here.
- Are you modifying network configuration from computer (SD plugged in a Linux PC for example)?
- If yes, what network configuration did you use?
I like to hear more from you soon!
