@balbes150I'll check the new image tonight. 
I finally have filmed everything I need for the video. I had a lot of issue's with capture devices not working properly and always had to redo it. 
So I installed it 4 times. And every time it didn't boot from NVMe, but instead from sd-card. Changing extlinux with the correct uuid from NVMe works. 
I did choose the correct way, you'll see it in the video. Tomorrow I should have it finished. It'll be a long one. Review and installation all in one...

@NicoD You can check out this image 20210228-legacy ?

I added a patch from 
 
https://github.com/armbian/build/pull/2650#issuecomment-787198231
 
to it to improve 4K.
 
Pay attention.
Before installing the media script or updating the system , freeze the kernel update, otherwise you will get the old kernel from the network repositories (this is not the correct kernel with errors).
 
p. s. the image is already fixed DTB to reload.

Reboot doesn't seem to be working. It either shuts down, or stays on without doing anything. 
Otherwise it all looks ok. I do have a problem with kazam when the media script is installed. I've had that too on M4V2 with media script in Buster, so it's not the image.
I'm filming everything to make the video. I'll not use Android to write the image, I'll link to the video of @gounthar instead. He clearly has more Android knowledge, and way more patience. 

Version 20210226. Fixed NVMe and added a separate DTB for roc-rk3399-pc (works with Renegade Elite) with Legacy kernel. After testing for several weeks u-boot-2021.01 on different rk3399, the transition to u-boot-2021.01 was made
 
I remind you that the configuration of DTB and other startup parameters is now performed in the file /boot/extlinux/extlinux.conf

For power management install :
 
sudo apt install xfce4-power-manager  

It works. OMG I'm so happy. You did an amazing work.

I'm stoked. I've got a bad habit of staying at a project until it's done. I should have done other things the last month, but every day I kept trying with the P1.
I'll finally be able to finish it and start with another board. And I'll be able to use the P1 as my main machine. And my M4V2 for gaming. Thank you.
 
I'll wait for that. I don't mind waiting a bit longer.

In a few hours, I plan to update the images on the site, including with a new version of Buster (which will all have the patched DTB enabled by default).

I did it. Somehow.

Seems to work fine on the M4.
 
Linux nanopim4 4.4.213-rk3399 #6 SMP Thu Feb 18 19:25:55 CET 2021 aarch64 aarch64 aarch64 GNU/Linux  

Now I checked on P1 without NVMe), with the "plus" file-video and sound are accelerated by 2 times, with the non-plus file, video and sound are normal. (DTB files from the site).
NVMe operation has not been verified.

Definitely, according to the picture, something went wrong. Can you do the installation again from scratch, and this time copy-paste the installation output? And also "armbianmonitor -u".

I've just installed the media script on the Station P1. Video playback is 2x speed. Either in Youtube with Chromium, or with MPV and a normal video file.
Everything sounds like the chipmunks.
I also think not everything went correct with the chromium settings. 

Problems are haunting me on the StationP1.  I've been trying for a month to make a video about it and never was able to have everything working. When not filming it often worked. But when filming... Quantum mechanics are against me.

Maybe it is possible to perform a simple recording of what is happening on the monitor on a regular video camera or take photos of your favorite moments ?

I don't use android, after version 4 (after googl messed it up and turned it into shit).
 
I totally agree

I found the marking of the sound chip - this is es8388

I don't have a good camera. I did take some pictures of the top, not from the bottom. I did film the replacing of the thermal pad, but it isn't sharp enough to see anything. I'd need to disassemble the whole thing to be able to see the bottom. 

There are some pictures of it here. https://download.t-firefly.com/产品规格文档/开源主板/ROC-RK3399-PC Plus - Specification.pdf?


I'm using a normal 1080p pc display. No tv. I'll try again. I also tried the focal mainline from your folder and it also didn't boot. Also stuck at those stripes. I didn't know USB boot worked. I'll try that too. 

@NicoD  I uploaded new Legacy images 20210204 to the site with support for WiFi NVMe and analog audio for the P1.

Here my Linux review of the Odroid N2+.
It has a beastly CPU, but is lacking in I/O.
Here's my video.

@NicoD try this image, it's with a new kernel and DTB.

@NicoD Can you try with the current version of Buster-legacy this DTB ? With it, you should have NVMe. There will also be a device for analog sound, but without patches in the core itself, the sound does not work (in the new image with patches, the sound and remote control work).

I meant the release of a new model P1 (if the manufacturer releases one), in which the M2 connector will be built into the main board (for example, as it is done on the Firefly rk3399 or on the NanoPC T4).
 
As for the photos, this is @NicoD, we have a specialist, I hope he can make them.
 
 
The good news is, I'm currently testing a new "old " kernel (legacy) that runs NVMe, analog audio, and remote control on the P1. I hope to upload a new Buster-legacy image with this core to the site soon. By the way, do I need to build more versions of Focal \ Bullseye, etc. with this kernel ?

It's looking better now. I removed the wire for the antenna from the frame, plugged it back in. And attached the frame.
 
They should have designed the case a bit higher so the hat would fit. But I like it like this. I'll try hirsute now. Been a while since I tried it.
