Thanks for the reply @fabiobassa I already tried with armbian-config and nmtui and no luck.
If i try to connect to the wlan0 the drivers fails I revive a text "Activatin failed: The Wi Fi network could not be found"
anyway i have some questions,
1 in the LibreELEC the working "rk3228b-box-a8.dtb" but in this image the dtb is for a rk3229 should I change or it dosent matter?
2 if Itransfer the system to eMMC via armbian-config, after i will not need anymore the SD card.. no.. do you recomand to do this, what are the benefits?
3 when i tried to install on the SD the minimal (non-desktop) image the led of the box lighted up(so i think that it had booted but on the TV i dont see anything, not even a script, it is normal?
4 I want to use this box as a parallel backup media server, mostly for emby server, vpn server, ftp / webdav server, and some program to sync files with other server, what version do you recommend to use, the desktop or minimal?
I was thinking at minimal because it light but i think that the desktop one can deactivate the ui, and in that case should be the same.. no?
