Ok i have finally booted. But kernel does not have snd-usb-audio. I would like to compile the driver from alsa-project sources but there is no linux-headers packege 5.15.123. I know that audio driver for allwinner T527 cant be done yet. But why snd-usb-audio is missing. Usb audio card can be substittute.

It worked! You need to keep .img files in the same folder as rkdeveloptool folder and run everything as sudo. Thank You very much!!!
andrius-vainorius@DELL-G5:~/rkdeveloptool$ sudo rkdeveloptool db rk3588_spl_loader_v1.15.113.bin
Downloading bootloader succeeded.
andrius-vainorius@DELL-G5:~/rkdeveloptool$ sudo rkdeveloptool wl 0 Armbianserver.img

Well we do not have such a version but you may want to take a look at this: https://docs.armbian.com/Developer-Guide_User-Configurations/#user-provided-image-customization-script

This is the official Armbian image Armbian_20.11.10_Rockpi-e_buster_current_5.9.14.img from  https://redirect.armbian.com/rockpi-e/Buster_current 
 
armbianmonitor -u output is here http://ix.io/2PDj
 
So far it works OK. I didn't do any special tests. Just set-up a WiFI accesspoint with hostapd (on bridge eth2/wlan0) and udhcpd. iptables for masquerading and just now accessing internet from my phone using
this AP.
ifconfig shows three Ethernet interfaces. the two real ones are eth0 and eth2.
Let me know if I could be of any help. Would be a pleasure for me to give a bit back to Armbian :-)
 
Both, RockPi-E and OpiR1+ generate a Kernel panic at the end of "init 0"  harmless AFAICS. Output is attached.

@Igor
True, the problem was related to DNS. I've fixed it by adding DNS nameservers as follow:
 
$ sudo vi /etc/resolv.conf
Modify or enter nameserver as follows:
nameserver 8.8.8.8
nameserver 4.2.2.4
 
Thank you once again!
