Lamobo R1: Revision 26
Lamobo/BananaPi R1
http://linux-sunxi.org/Lamobo_R1
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

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