Installation issues TVBOX MINIX U9-H

[Sandro7]

Hi, I cant run armbian (balbes150 version) from SD - TVBOX MINIX U9-H (Amlogic s912 2/16) just dosent boot. TV shows dark screen more than hour.

 

What I'm doing wrong?

 

1. I downloaded https://users.armbian.com/balbes150/arm-64/Armbian_20.10_Arm-64_buster_current_5.9.0.img.xz

2. Flashed it with balenaEtcher to SD

3. Renamed u-boot-s905x-s912 => u-boot.ext

4. Made changeds in extlinux.conf

LABEL Armbian
LINUX /zImage
INITRD /uInitrd

FDT /dtb/amlogic/meson-gxm-q200.dtb
APPEND root=LABEL=ROOTFS rootflags=data=writeback rw console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0

5. Inserted SD and used toothpick method

 

 

Same time I can boot Coreelec from SD. What I'm doing wrong? May be there are other armbian build or ways to try?

Coreelec is not ok for me because of restrictionst that not allow me to install home assistant supervised(

You apparently didn't read the FAQ post carefully as this is addressed:

 

Note2: If you have previously run other distributions on the box such as coreelec the below installation will not work.  You will need to restore the original android firmware before attemping the install.  coreelec changes the boot environment in ways that are incompatible with these armbian builds.

Thank you very much! You are right. Reseting to original firmware - works for me!
