Rock Pi x Libreelec

Good morning.I’m trying to install Libreelec on a Rock Pi X, but after the Libreelec facility you don’t start and I get mmc mistakes. Have I tried Ubuntu as well and, apart from Wi-Fi’s lack of functionality, the wireless keyboard isn’s not working. But it’s my fault or was wrong

I managed to install the Libreelec, but at the start I have a remote communication error and it does not work with HDMI CEC’s audio on TV. Has there been anything in Bios?
