I see. But how exactly can I resolve these errors then?

what do you see ? what do mean resolve error ?

you do not need toothpick , you do not need recovery , only insert SD-Card and start the box

 

befor patch

bootloader-->internal memory-->android

 

after patch

without sd-card

bootloader-->sd-card-->usb-->internal memory-->android

or with sd-card

bootloader-->sdcard-->debian

@Rohaaq  A further comment that might help clarify.  Applying 'multiboot' is a one time operation.  It changes the boot environment which only needs to be done once.  So if you have properly applied multiboot (through either toothpick or update methods) then you are done and subsequently all you need to do is insert your sd card and it should first try to boot from there before falling back to booting android from emmc.  If it doesn't boot what you have on your sd card, you either haven't properly installed multiboot or your sd card is incorrectly setup.

Ohhh. Sorry, I didn't quite understand this the first time. Installing the .zip file definitely did something, so I reckon that's probably fine. I suppose then there's something wrong with how I've formatted the SD card, but as far as I understand the only thing I need to do is edit the one line of the uEnv.txt file. What else could I be missing?

 

Thanks for the help so far, I really appreciate it.

this is still a beta for this tv-box.

 

yes when boot from sd-card you should edit uEnv.txt with right dtb file,

but it could happen that none of the dtb work.

if this happen, than please try one of the older Armbian S812 Version 5.xx with Kernel 3.10.xxx there is a higher chance that one dtb is correct for your box.

 

be aware the dtb files not changeable between 5.xx Kernel and 3.10.xx Kernel

I bought it from  TAOBAO in China.
It has S805 CPU.
SD Card Write Armbian_21.02.0-trunk_Aml-s812_bullseye_current_5.10.0_.img and meson8b-mxq.dtb, the network works, but the screen does not appear.
(At Armbian_5.67_Aml-s805_Debian_stretch_default_3.10.108_desktop_20181207.img & meson8b-mxq.dtb,  Display screen on.)

Someone helps the screen appear on Debian Bullseye.
Or I'd appreciate it if you could help me install the Retropie & Lakka.

How about other dtb files from armbian 21.02.0 any other with display , its more easy to look at dtb files from same Kernel.

 

dtb files from 3.10.0 to 5.10 are more difference -->that why there are not compatible .

Thank you for your interest!

 

As you said, I tried other DTB files.

 

meson8b-odroidc1.dtb   The display is finally ON! But the network is dead.

meson8b-mxq.dtb   The display output is still dead. But the network works, so I can access SSH.

 

So I changed DTB to DTS and tried to fix it. But there's an error message like the picture below.
Can you give me some advice?

 

There is an error even if I don't fix the file and just do a two-way conversion.

DTB -> DTS -> DTB

your secound dtc string is wrong from dts to dtb

-I = input type you have dtb should  dts

-O = output type you have dts should dtb

-o = output file = ok

 

also odroid use realtek LAN but many HDMI CRC and HDMI i2c

ODROID C1 source file

mxq use internal(amlogic) LAN and standart HDMI output

MXQ source file

 

 

i thing your box need also the HDMI Communication CRC and i2c pins to work
