Thank's a lot !
 
but i think H96 Max+ (it have Android 8.1 PCB:8D4 ) and H96 MAX (it have Android 7.1.2 PCB:D4  ) is not the same motherboard :
 
H96 MAX PLUS = PCB is labelled as "RK3328_8D4_V1.1"

 
other Firts Model have mxq_rk3328_D4_A  ( i find some MX10,MXR Pro ... )

                                    mxq_rk3328_D4_B V1.1 ( A5X MAX, ...)

 
H96 MAX PCB is labelled :
                          h1=mxq_rk3328_D4 v1.1 ,

                          h2=mxq_rk3328_D4 v1.2

                          or last version h3=mxq_rk3328_D4 v1.3 (my picture )
 
But i will try this dts quickly

Rockchip default UART are at 1500000 baud.

Assemble the image is not a problem. My goal is somewhat wider. Develop a comprehensive system (image, set of scripts, instructions, etc.) for the end user, which will allow the average user to easily run Linux on the TV box. A typical user should have an easy-to-play set of system startup steps. Downloaded. Unpacked. Recorded image (possibly performed a simple operation to copy additional files). Launched a TV box. Performed a simple operation (or simple steps) on an existing system. And get a ready working system.
 
Everyone has their own criteria for a reasonable price. I have been working with different TV boxes and other electronic devices for a long time and I know well what to pay attention to in order not to regret the time spent (money). Let's try to count. The model you are referring to has serious (for me) cons.
1. LAN 100 MB.
2. Power supply 2A. This means that you will not be able to fully use all the features of the device. So have to spend money to buy a new PSU.
3. Cooling system. Without it, to use all the features of iron is not possible. To power the fan will have to either use a USB port or an external power source.
4. In the set there is no cable for firmware. More expenses.
5. The quality of the components used and the Board (marking all elements that points to Maskrom and UART). This ensures that all models are identical and the manufacturer does not make a "team hodgepodge" of what was at hand.
6. The manufacturer pays great attention to technical support and is ready to cooperate (this is important for me).
7. The presence of the OTG port.
 
Specifically about this model I can't write yet (I don't have it yet). If you unplugged the PSU, all parameters are reset. If the electricity flashes, the TV box will turn on itself, without your desire. By the way, for this reason I like the Vega S96 it has an additional battery (as in the BIOS on the PC) and is not afraid of power failure.
 
Don't sacrifice.
Producer already showed interest and offered to send me a sample. By the way, this indirectly suggests that the manufacturer is interested (and understands) the importance of expanding support for different systems in its products. So that customers who buy its products can use it much wider than just a TV box.
 

so with : Armbian_5.44_S9xxx_Ubuntu_bionic_4.18.0-rc5_server_20180727.img.xz
dtb.img with p281 dtb
 
OK to compile i add some time -j4 and some time -j3
because the swap don't work and the system freeze -j3 use less memory ( ihave only 1GB )
if you have a trouble (freeze) to compile something :
in th rep of the compil
mc -e C.sh
put the compil
chmod 755 C.sh
in console (not ssh, not in telnet ) lanch
./C.sh &
 
i add "--enable-hardcoded-table" to have some cpu gain
 
i don't put x265 (i must have an eyes on the errors after if you want it , add --enable-libx265 at the ffmpeg compile at the end )

i am waitind the end of the ffmpeg compile ...
(  all compile take one hour )

I boot !
i start ffmpeg v4.01 compil

with this command :
/root/bin/ffmpeg -vcodec h264_aml -i /root/Sintel.2010.1080p.mkv -vcodec copy /tmp/test.mp4
Works
But to transcode :
/root/bin/ffmpeg -vcodec h264_aml -i /root/Sintel.2010.1080p.mkv -vcodec h264 /tmp/test.mp4 -loglevel trace

look for solution ( but i have a doubt on this old ffmpeg )
