ver 20200901-dev fix USB gxl\gxm

The new version of the image is 20200820.
The configuration for the core build has changed significantly.

ver 20.08 (20200812) kernel 5.7.14

ver 20200723

Thank you @balbes150 for the new bionic build!
Armbian_20.05.6_Arm-64_bionic_current_5.7.2_20200612.img.xz (plus via armbian-config added desktop) runs nice from internal on two newer(those strange ver. 4.x pcbs with wifi and bt working..) and one older/normal (no wifi) x96minis 2/16 with all programs I want/need at low temperatures(around 60°C).
 

Version 20200612.
Kernel 5.7.2.
updated the build system, supported build on aarch64 Focal.

Version 20200605.
Added WiFi support for Allwinner Tanix TX6 (H6).

It worked, thank you very much for the information, I was very lost here.  Now everything is going smoothly.

I guess it is more a new installation than an update what you want..because I have just p281 devices with s905w chip I can only write how I proceed on these devices, but as s905x and s905w are quite similar, that should work for you too: Burn image on card, configure that dtb is working for your hardware in uenv.txt"Complete copy OS to eMMC "
If new system runs good from sd card, just boot from it, open a terminal and type:
 
sudo /root/install-aml.sh after few minutes the script should have copied(/usr/ takes a while..) the stuff to eMMC and prompt:"Complete copy OS to eMMC "
 
If that fails to reboot 20.05.5 image from internal after that, maybe try in terminal on boot from card to copy (again):
sudo /root/install-aml-s905-emmc.sh ..but for me on 5+ amlogic p281/p212 devices install-aml.sh works perfect..
 
 

Version 20200519.
This version is fully built not mediocre on the ARM platform (rk3399).
I checked how the images work on different models, and no problems were found. The system works identically to the version built using the old scheme via cross-compilation on x86. While these images do not have u-boot and to run from the SD card on RK3399 add u-boot, as described at the beginning of the topic.
Now anyone can build their own version of ArmbianTV not mediocre on their device.

ver 20200514 kernel 5.7-rc5

Contact the hardware manufacturer to develop and source the correct DTB for the mainline kernel with support for all devices for your models.

For me on the x96mini work all/most versions until 19.11.4 (the 19.11.5s I tried didn't boot or booted but had no usb working) with the meson-gxl-s905w-p281.dtb
For me worked to boot via toothpick method after doing the fake update(there was the footer error, but afterwards balbes' Libreelec booted from card..). Afterwards I can boot any of the armbian images before 19.11.05 on the x96mini 2/16. Install on eMMC works too, but for newer (universal boot images) install has to been done not via armbian config tool like on 5.9x-builds, but via install script in root directory. To get the install successful you need to delete rk and aw u-boots on card as boot partition on eMMC is just 128mb but with all u-boots it is more.
For newer builds 19.11.5 and on I have to ask in mulit platform thread, why those doesn't boot for me with same dtb settings I use for years on that device..
 

If after adding u-boot does not start, add UART and see what happens.
 
 
 

And yet again, duct tape saves the day!   

If everything works at 5.0, there's no point in dropping to 4.20.
