i did full git clone, not --depth 1
git clone https://github.com/paolosabatino/armbian-build.git cd armbian-build git checkout -t origin/rk3318  

Ok, I've installed updated image from first post:
Armbian 21.08 - Ubuntu Focal desktop [xfce] - mainline kernel 5.10.34 - Build date: 2021-05-05 Burned to emmc with multitool, and it works, connected to wifi without issues. Logs from this kernel: http://ix.io/3njG
After the first reboot it had a problem with starting X (restart loop). Solved it with connecting via ssh, and:
sudo apt update sudo apt-get install lightdm > ... > Preparing to unpack .../lightdm_1.30.0-0ubuntu4~20.04.1_arm64.deb ... > Unpacking lightdm (1.30.0-0ubuntu4~20.04.1) over (1.30.0-0ubuntu3.1) ... > Setting up lightdm (1.30.0-0ubuntu4~20.04.1) ... > ... I noticed one problem with apt - it is very slow, not while downloading, but later, it takes minutes while "Reading package list ..., Building dependency tree .. " etc.
 

It is all thanks to you, @jock and other people from this great forum. The desktop experience is noticeably better then rk3229, 
OpenOffice Calc starts in 6s, GIMP in 13 (afer reboot), this forum page reloads in 10s in chromium. It feels a bit laggy but still very usable. 
On the other hand, working via vpn on remote windows desktop is just comfortable. I'm considering to use it as cheap, preconfigured box for remote employees in the next covid wave.

My board is equipped with 4GB RAM, 64 GB emmc. Armbian Focal current is correctly discovering those resources. Although wifi chip supposed to be AP6334/BCM4334 is realiy an AP6330/BCM4330

Thank you, great work!
It worked on the first try. Using multitool I've installed Armbian_21.08.0-trunk_Rk3318-box_buster_current_5.10.32_minimal on my:
Android TV H96 Max RK3318 4/64 GB
I set the frequency to 1.3Ghz and the box is running stable from eMMC.
