What build of armbian are you using?  Please provide the exact steps you are having problems with, your description of the problem is not clear.

i use

ARMBIAN_20.10_Arm-64_buster_current_5.9.0

and

i use ARMBIAN_20.10_Arm-64_focal_current_5.9.0

Maybe the dtb file Is not good ?

@tasknodes as SteeMan requested, you should provide details and steps of how you installed Armbian. also provide details of what caused a boot failure and details of what error messages or logs that you saw on your tv/monitor.

I hope this helps... For the TX3 Mini, I used the distributions listed on https://www.armbian.com/amlogic-s9xx-tv-box/. Here's what I did:

* Create a bootable image using Rufus (following the instructions).

* Once the image was created, I went to the SD card's storage drive on a PC and made the following changes:

* In the root directory of the SD card, I copied the file u-boot-s905x-s912 and pasted it as u-boot.ext.

* In extlinux\extlinux.conf, on line 4, I changed it to "fdt /dtb/amlogic/meson-gxl-s905w-tx3-mini.dtb".

* I ejected the SD card, inserted it into the TX3 Mini, and turned it on.

If it doesn't work, try a different distribution.
