Seems you have a 5.10 compatible DTB. You can try with legacy kernel or with mainline and box-demo dtb. Legacy maybe the best for kodi.

Actually the kernel needs a dtb that is integrated in the UEFI EDK2 firmware and gives the dtb to the kernel EFI stub. If you are using a firmware for another SBC the dtb passed through is wrong. Wait a minute.... I'm wrong. EDK2 gives it's own drivers to the kernel. The above is for UEFI U-BOOT.

No way. I get 100% with 1080p.

I have got video player acceleration with flathub clapper for 1080p with 20% CPU. Enough for me. Based on hantro driver so no 4k. There's also a @jock tutorial for debían to enable ffmpeg v4l2-request that is equivalent. I have understood that must enable webrtc-pipewire in chromium, isnt It?

@hotnikq Can you explain this? Is it mainline? Is the repository package or compiled or something else? I cannot get video acceleration in youtube. I have tried with gstreamer web browsers, ffmpeg with v4l2-request and firefox, but nothing. It works very well in video player and web video acceleration it's just the last item to get a decent desktop computer.

So you agree to take the risk and anything that happens will be your responsibility. You don't have to delete android and should be working without knowing what you are doing. However it's possible to burn the box because of wrong configuration. I have an rk3328 box that can not run android anymore because of hot weather and wrong seller configuration but runs happily linux with the right one. The first step is to burn multitool in sdcard with balena-etcher. This utility can wipe your android box, so be careful. You can find it in Installation (via SD card): This way we can know if your box can boot from sd card. Insert the card in the box and power on. You can make a backup of your box there but be careful !!! Don't do anything more.

If you can't loose your box don't try anything. There is a real chance to brick the box when you are not used to this kind of tinkering. Your goal is posible as I have 4 boxes doing that but the task is not easy and everything is not going to work (wifi, ethernet, bluetooth maybe never work).

Have you booted multitool from sd card? If you can do that then you can with the correct u-boot.

I think you have to burn an android imagen on It and follow from there

Why a custom kernel? Mainline is fully supported.

I don't use the display because I tinker just for fun 🙃 I believe you must have nodes for vfd and drive the display with a service like openvfd. Here is one related for an rk3566 android box. }; meson-vfd { compatible = "amediatech,aml_vfd"; dev_name = "meson-vfd"; vfd_data_gpio = <0x6d 0x14 0x00>; vfd_clock_gpio = <0x6d 0x15 0x00>; vfd_stb_gpio = <0x6d 0x16 0x00>; status = "okay"; };

I see , you have inherited wrong nodes from your github downloaded file that are not present in firefly or box-demo dtbs. Maybe you have to use these ones as reference.

I think it will work if you have firmware and loads. Maybe that refuses. dmesg | grep -i error '

Delete this: wifi@1 { compatible = "brcm,bcm4329-fmac"; reg = < 0x01 >; interrupt-parent = < 0x63 >; interrupts = < 0x0a 0x04 >; interrupt-names = "host-wake"; pinctrl-names = "default"; pinctrl-0 = < 0x64 >; phandle = < 0xf8 >; };

Maybe there is already a DTB in GitHub.

How many usb do you have?

You don't have to chainload, rk3566 is fully supported in mainline. You need a mainlined dts.

With ddr4 the best is 1506mhz

Yes, DMC is deprecated.

I quess this is an android boot so the kernel is 4.19 and ddr frequency is stored in DTB file. So don't care about freq. With kernel 5.x the frequency is given by the bootloader and then you must pay atention.

So you want to link your box to the printer with ethernet and give the printer wifi? This is easy with a wifi-repeater-bridge but you want your box to do that. If you can give the printer an static IP and gateway I think you can do. Just asiggn static IPs to all the adapters within your router's IP. For exemple: Router IP 192.168.1.1 Printer IP 192.168.1.50 Printer Gateway 192.168.1.52 Box IP 192.168.1.51 Box Gateway 192.168.1.52 Wifi IP 192.168.1.52 Also you can bridge adapters like this https://www.baeldung.com/linux/bridging-network-interfaces

Good job Maybe the attached file is better for your build. ¿How do tou get the log? quartz64_defconfig

But eth0 is working, isn't it?

IO voltages to the trash can, RTL will provide .... rk3566-box-demo_rboxr2_8.dtb

Another idea Change gmac1 to gmac0 in pinctrl-0 rk3566-box-demo_rboxr2_7.dtb
