You are the best balbes150! Thank you!
According to information from the representative of the LE community, he is ready to discuss the participation of Khadas to the development of the project LE. If You have the desire, You can create a LE on the forum topic, or ask directly in PM to the user Chewitt.

Great news!
Where you got the information? I didn’t found any topic about this 
From correspondence with Chewitt. I understand his statement that You can write him a PM or create a topic on the forum.

Are there any news about Khadas VIM support in official LibreELEC release?
I have been watching how this thread goes. Unfortunately, the latest OpenElec firmware was from four months ago, not updated as frequently as the Android firmware.
I really like the looking, but lacking efirmware support made it less attractive.
I have added a device tree for Khadas Vim board that should make my LE community builds work. Please let me know if it works as I don’t have the board. You can follow the development here: https://forum.libreelec.tv/thread/2156-8-0-2b-libreelec-8-0-for-s905-s905x/

Then Khadas stuff should arrange you an
@Terry @Gouwa
which u-boot should be flashed in order to boot directly to micro SD / USB which have @kszaq libreelec image?
I found an older post where you wrote ubuntu-rom-for-khadas-vim :
Erase the eMMC and Khadas VIM will boot from the SD card automately.
Force enter into MaskRom mode first, then Khadas VIM will try to boot from SD card.
Long press the Function button to boot from SD card.(Need upgrade to the latest ROM first)
I did erase eMMC and on reset I just see this:
GXL:BL1:9ac50e:a1974b;FEAT:ADFC318C;POC:3;RCY:0;EMMC:0;READ:0;CHK:AA;SD:0;READ:0;CHK:AA;USB:8;
it was an Android Nougat u-boot/image before erase command.
With Android installed on eMMC, you should be able to boot my build from SD card by using Reset button for the first boot unless Khadas’ u-boot behaves differently from what I know from TV boxes.
I also did ‘dd’ the u-boot-bin.sd-bin (from Vim_Uboot_170121.7z) as postet in that above thead from @Gouwa and erased eMMC again. But i have now only bootloop.
@Khadas Team please assist…

Not sure but I guess you didn’t have a HDMI Cable connected with VIM device, can you try again with a HDMI cable plug in?
It is for sure plugged in. I have had on TV picture from Android Nougat. still connected. But only loop. Can you check this @kszaq image yourself and let us know how to boot it?
As far i understand there are two partitions once they are burned to microSD (using Refus). Then i copied @kszaq gxl_p212_2g_kvim.dtb to first partition and overwrite dtb.img.
Tried to boot nothing happen over serial console.
Then i ‘dd’ that u-boot.bin.sd.bin to microSD by using Linux (tried u-boot.bin.sd.bin from Vim_Uboot_170121.7z and Vim_Uboot_170304.7z). Erased eMMC and only that bootloop.
Downloading the LE ROM, will keep you updated later.

I did it now everything on Linux host, and in current state it does not boot. In your instruction you format sdb1 partition and flashed u-boot.bin.sd.bin but that I cannot do with @kszaq Libreelec build as this is where kernel and dtb files resides.
Here the commands I used:
[root@vdr01 /]# cd /opt/kszaq/

With micro SD prepared with above instruction and nothing on eMMC i just see this loop:
LOOP:2;EMMC:0;READ:0;CHK:AA;SD:0;READ:0;CHK:AA;USB:8;;LOOP:E;EMMC:0;READ:0;CHK:AA;SD:0;READ:0;CHK:AA;USB:8;
so the u-boot.bin.sd.bin must be ‘dd’ to microSD crad in order to boot from it when there is nothing in eMMC.
Hi, Vrabac:
Here can boot into LE ROM from kszaq, but it seems that the ROM not works fine on VIM yet.
1) Upgrade to Vim_Marshmallow_Root_170303

Anything you need me to assistant just let me know.
Thanks.
Yes, see below:
Can you build a printing log enabled dtb for me? Or just figure out the source code you used on current build.
Thanks!
I used Vim_Marshmallow_Root_170603.7z and its u-boot as I don’t have 170303 version here, but i guess that is minimum u-boot version required right @Gouwa?
Anyway have same boot output while booting @kszaq libreelec build.
....
[ 0.021087@0] console [tty0] enabled
[ 0.024672@0] bootconsole [earlycon0] disabled
domain-0 init dvfs: 4
@Gouwa source code of this version should be 8.0.2b.
And Khadas VIM device tree can be found here.
