upgrade to unsupported armbian

This board was last supported on jessie, but it's fully supported in upstream so I did upgrade to latest Armbian as of 2021-05-29.

u-boot

sdcard already had u-boot installed, so I didn't have to touch this in first step. To update
u-boot do following:

root@r1:/home/dpavlin# apt install u-boot-sunxi

root@r1:/home/dpavlin# dd conv=fsync,notrunc if=/usr/lib/u-boot/Lamobo_R1/u-boot-sunxi-with-spl.bin of=/dev/mmcblk0 bs=1024 seek=8
449+1 records in
449+1 records out
460103 bytes (460 kB, 449 KiB) copied, 0.0449233 s, 10.2 MB/s

distribution

First, I did distribution update to stretch and buster and than added

root@r1:/home/dpavlin# cat /etc/apt/sources.list.d/armbian.list
deb http://beta.armbian.com buster main

kernel

and installed latest sunxi kernel image

apt install linux-image-edge-sunxi

After reboot I was greeted with new kernel

root@r1:/home/dpavlin# uname -a
Linux r1 5.12.7-sunxi #trunk.33 SMP Fri May 28 07:03:36 UTC 2021 armv7l GNU/Linux

configure switch

https://www.kernel.org/doc/html/latest/networking/dsa/b53.html

root@r1:/home/dpavlin# cat /etc/network/interfaces.d/br0
auto br0
iface br0 inet dhcp
#iface br0 inet manual
#	address 192.168.1.1
#	netmask 255.255.255.0
	bridge_ports eth0 wan lan1 lan2 lan3 lan4

	bridge_stp off
        bridge_waitport 0
	bridge_fd 0

Ports are (left-to-right, looking from back of board starting at edge towards hdmi connector):

br0: port 3(lan1) entered disabled state
br0: port 4(lan2) entered blocking state
br0: port 4(lan2) entered forwarding state
br0: port 4(lan2) entered disabled state
br0: port 5(lan3) entered blocking state
br0: port 5(lan3) entered forwarding state

br0: port 6(lan4) entered forwarding state
br0: port 6(lan4) entered disabled state
br0: port 2(wan) entered blocking state
br0: port 2(wan) entered forwarding state

switch connects all ports on boot
