Hi there,

I have a very strange issue:

 

kernel 5.4.14-rockchip64

debian_version 10.3

Armbian 20.02.0-rc1 stable

cable is OK - checked

eth0 in /etc/network/interfaces.d/eth0 set  to dhcp

----

unfortunately the rockpro64 gave up with an hardware ram issue

The unit was replaced and luckily I have an image: March 3, 2020

which was OK and fully functional.

 

Today I threw it on the SD-Card and I do not have a NIC at all.

A.m. Data drawn from the OS

 

hwinfo issues RTL8211F

irq:0 27 "eth0"

 

lshw

network:0  eth0 id9 with MAC

network:1 DISABLED dummy0

 

ip a

dummy0 down (Never had this scrap before)

eth0: NO CARRIER

 

ip link show

dummy0 down

eth0: BROADCAST UP...  state UP

 

Any ideas what happens here????

What am I missing???

 

Thank you - willi

 

btw: my rockpros take about 90 seconds to boot up and I do have to power on/off the screen 2 times before the interface

realizes that it has got a screen????

You are using some old release candidate build - perhaps that is the reason for your troubles? Preview builds never had any end user support. They were made exclusively for hunting bugs.

You need to run latest image https://www.armbian.com/download/ (or at least updated to latest)

OK - will use buster 2020-06-03 and revert with result

buster 2020-06-03
installed without any issues - screen recon OK, screen size OK, network dhcp out of the box
Thank you

further report of findings:

Armbian Focal desktop mainline based kernel 5.4.y - no eth0

Buster desktop 5.4 - no eth0, hwinfo says hardware OK and shows eth0, but no entry at /dev

Buster server 4.4 - eth0 OK

 

buster server 4.4
Would be good if there is a solution for buster desktop 5.4 as the installation of i.e. LXDE on buster server 4.4 is crude - somehow..

No pulseaudio and even apt-get install lxde delivers only the lxde-core.
Funny that one have to install xorg before as the lxde packages does not resolve the dependency.

You can try the "old school" way  by adding the following in /etc/network/interfaces :

# Wired adapter #1
allow-hotplug eth0
iface eth0 inet dhcp

 

tried with dhcp and static at /etc/network/interfaces.d/eth0 but with auto eth0

added allow-hotplug eth0 too...

 

currently on ubuntu 20.4

but hell - ping changed from network not reachable to Destination host not reachable...

some efforts..

 

still no network device in /dev

but ethtool -S eth0 shows some data - almost all 0

 

Can't help but I think there is a bug between Kernel 5.4 and network?-manager

sorry but I am not very good in driver and kernel tasks my focus is on LXC-Containers
