Armbian 24.5.0 Bookworm images (linux-6.1/linux-6.6) for TVBoxes: Vontar KK MAX / HK1 RBOX R2 / HK1 RBOX R3
(the same dts/dtb should work for these TVBoxes)
 
Here is a dts and dtb files, working reworked for mainline:
hk1-rbox-r3-profile-kernel-6.1-6.6.zip
 
(original dts and dtb from TVBox rk-kernel-orig.zip)
 
Checked the following:
HDMI - works (need to check hot plugging) HDMI sound - works USB 2.0 - works USB 3.0 - works SPDIF - should work (I cannot to check) SD-Card booting and detection - works eMMC install on it (/sbin/nand-sata-install) and detection - works RKDevTool installing and loading images on/from eMMC - works GPU (bugs/frizzes on mainline are not canceled) - works Hardware video acceleration(except for browsers) - works Dualboot if you flash new bootloader (SD-Card boot high priority) - works  
Here are the compiled Armbian images (Bookworm only) with integrated dtb:

The one of this box itself is HK1 RBOX R3, the photo shows the pins for short to go to the Maskrom bootloader and UART pins:
 
A working bootloader(supports dualboot) on this hardware for RKDevTool tool just in case:
Loader.zip
 
 
Please note that RKDevTool flashing utility only needs to flash the .img file with the bootloader, i.e. you need to unpack the .xz archive somewhere first (for ex. you can use 7-zip).

Recommendations for installation on eMMC
 
----------------------------------------------------
For those who want to build Armbian themselves, here are the instructions:
 
UPD:
Added to images "f2fs-tools" package, added loader to support dualboot without touching the original Android(or other OS) image on eMMC - priority is given to SD-Card.
Boot will be from SD-Card if there is on boot partition exist folder and file \boot.scr or extlinux\extlinux.conf - uboot(both: original Android and compiled for Armbian) searches for this path and file if it found this file, it will load from device which contains this file. mmc1(SD-Card) - first, mmc0(eMMC) - second.
For correct priority loading it is necessary to replace the main bootloader which is in the archive Loader.zip - if you have an Android it is enough to flash only this bootloader as Loader at 0x0 offset using RKDevTool utility, the rest of the eMMC part should not be touched if the OS and settings we need are there. U-boot on eMMC must be original or Armbian and preinstalled at offset 0x4000.
Instructions:
(remember, uboot must be on eMMC (even the original Android or Armbian, i.e. if you erase the eMMC - the boot will not work) and this is relevant if you have installed the original MiniLoaderAll.bin, which does not support booting from SD-Card, but only from eMMC. Some TVBoxes may already have a bootloader that supports SD-card booting.).
