Hello @SteeMan, when I managed to run and install the previous version, I was excited and believed that I could run a current version, because I thought I had "unlocked" something in the hardware, but it was not possible to run through the SD Card. I could record a video to show the steps I followed, but I speak Brazilian Portuguese and I don't speak English (I translate the texts via Google Translate), you wouldn't understand me. But basically what I did was trial and error, I tried the "Focal" and "Bullseye" versions, and 6 months ago I talked to you (TX3 Mini without reset button does not boot), and you suggested me to test all available dtb's and that's what I did, were almost 50 attempts on each of these versions, and the common errors I had were: "kernel panic - not syncing: asynchronous serror interrupt armbian", "memory limit none" and finally there was a moment when I managed to access a console, but without success to advance appeared "(initramfs)".
So searching here on the forum I saw this link and decided to try, and by "luck" I managed to run it on my first attempt with an interface, I even installed it on my eMMC, but I needed to install Open Media Vault and I discovered that it does not run on Linux with an interface , so I decided to run it with the same version without interface and once again I managed to install it in eMMC, and now I'm running it without many problems, I have an Open Media Vault installed, an external HD connected and I also installed and configured Emby ( this one I'm still trying to find the best setting, as it crashes with some movies when transcoding because of the modest hardware).
If you have other tests I can run, I'd be happy to help.
