These are the tests that I have carried out with my RK3318 (HK1 SUPER):
To boot any Libreelec image on sdcard, you must always first install any Armbian image in internal memory with the multitool. If we have the memory with Android or the internal memory erased, Libreelec does not start.
In LE10 official Libreelec versions you have to inject trust.img, in LE11 development versions of Balbes150 trust.img is already included.
I have to use the DTB rk3318-a95x-z2.dtb and everything works great:
Video decoding HW --- OK
Led --- OK
Ethernet --- OK
SSH and SFTP --- OK
Remote control --- OK
WIFI or Bluetooth --- NO. (Attached log and dmesg. I also attach photos of the hardware).
Installing Libreelec in internal memory makes the tvbox brick. With Multitool, Armbian and bridge on the board it is easily unbrickeable. I haven't tried this yet: https://forum.libreelec.tv/user-post-list/27218-jps1x2/
