Many thanks to all those who helped me launch the TV-box, I am very grateful to these people who help out newcomers with their advice. Thanks jock, I deleted brltty using the command: and oh, a miracle the board worked, the connection to the printer took place!

I read this from the above link. I used Armbian_22.05.0-trunk_Rk3318-box_jammy_current_5.15.35_xfce_desktop, installed Klipper on a TV-box, installed Klipper firmware on a 3d printer (my son has an Anycubic Kobra 2 neo). And who would have thought that the TV-box does not see how the printer is connected under the Klipper. It says from the network address that the printer is not connected. I gave the command ls /dev/serial/by-id/*, in response, the directory serial does not exist. I looked at it - it's not there. Where to dig next?

Thanks for the help with solving the problem of the SP2734C chip, I found a simple solution see the link https://psenyukov.ru/установка-armbian-и-home-assistant-на-tv-box-h96-max-на-процессоре-rockchip-rk33/ everything worked after the reboot. It also describes the solution to other problems. Have a nice day!

I have placed a file nvram_2734с.txt in the /lib /firmware /brcm directory, no miracle happened, WiFi did not connect (Photo1). I inserted USB WiFi, WiFi did not appear, but another wlan1 network appeared (Photo 2), then the result rebooted without removing USB WiFi (Photo 3). The board and USB WiFi (Photo 4,5). I think if you can somehow disable the sp2734c, and USB WiFi drivers may be suitable. I don't really need Bluetooth, I'm making my son a 3D printer on clipper. Can you tell me a way to solve this problem?

I'm sorry, I don't know much about Linux, but I came across the H96Max 4k Ultra HD TV set-top box (rk3318), the rk3318 v.1.4 board, I wanted to install armbian on it. I did everything according to the instructions, the system was installed, I load from it, but Wi-Fi does not connect, although it shows that it sees 2.4 and 5 MHz networks, asks for a password but does not connect, the SP2734C chip. Bluetooth got up confidently and works, please advise me with the installation of armbian, maybe somehow disconnect the chip from the device, and connect Wi-Fi via USB. I read about the nvram file, but I did not understand where to write it, at what point, since, as I said above, I am not friends with Linux.
