Minix NEO U22-XJ Max and LibreELEC

    Hi. I have MINIX NEO U22-XJ MAX. Now I want to run LibreELEC. Unfortunately there is no suitable dtb tree. TVBOX starting with Ugoos AM6 Plus dtb, but it doesn't work as it should. WiFi not working. Is there any way to make a proper dtb? I can also remotely provide the necessary information about the tvbox hardware. I using linux, so I can run commands via ssh.

    Sorry for my bad English.

    It's an S922X device so perhaps try the Beelink GT-King file, they're both based on the W400 reference design. What WiFi chip is inside?

    With Beelink GT-King working as with Ugoos AM6 Plus device tree.

    Wi-Fi - not working

    BT - working

    Remote control via USB dongle - not working (USB 3.0 ports not working)

    LAN - working

    HDMI CEC - working

    I am not sure what command can be used to see what WiFi chip. I asked ChatGPT what WiFi chip is used, I got the answer that Broadcom BCM4356.

    I used dmesg | paste maybe the http://ix.io/4vgv results will help to solve the problem?

    Code
    cd /storage/.update
wget https://chewitt.libreelec.tv/testing/LibreELEC-AMLGX.arm-11.0.2.tar
reboot

    ^ please update to that image and share the boot log again. The WiFi card appears to be the newer BCM43752 chip (as that's what the BT driver loaded firmware for) but it's odd the kernel doesn't show any attempt to probe SDIO. I can ask the Minix devs for the Android dts and schematics to look at.

    Boot log http://ix.io/4vkm

    The boot log shows the kernel probed SDIO and loaded firmware this time so there should be a "wlan0" device listed if you run "ifconfig" but there are ieee80211 errors. See if "iwconfig wlan0 power off" stops them? .. and also try to create a WiFi connection.

    After reboot sometime not working CEC and still not working Wi-Fi. Again I rebooting device and CEC working, but ifconfig not show wlan0. Again rebooting and CEC work, ifconfig show vlan0, but in network not showing my home WiFi SID. I tried to disable LAN connection, but but wifi still not work. Also I tried via command line scan wifi but no successfully.

    LibreELEC:~ # connmanctl

    connmanctl> agent on

    Agent registered

    connmanctl> scan wifi

    Check/set the Wireless Regulatory Domain setting in LE network settings for your country. Perhaps the router is advertising on frequencies that are not visible under the default config. Then clean boot and run "journalctl | paste" and share the URL.

    After rebooting the tv box again, WiFi was not visible after the ipconfig command. Even after rebooting several times it did not appear. After unplugging the power and plugging it back in, wlan0 appeared. After setting the WiFi parameters according to my country (Lithuania), the WiFi still does not work, it does not show the SSID of my wireless network. I attach the journalctl log. http://ix.io/4voJ
