Efforts to develop firmware for H96 MAX V56 RK3566 8G/64G

[GmP]

First of all, thank you to  @Hqnicolas and all the members for this great effort.

 

Just bought an H96 rk3566, having this hardware configuration:

BOARD LABEL: HCY-RK3566-1X32-V20 2023-01-13
SOC RK3566
PMIC RK809-5
LAN RTL8211F
DISPLAY FD6551
WIFI AIC8800D40
eMMC H26M74002HMR - SK Hynix eMMC 5.1 NAND Flash 64Gb.

 

 

It seems to be a mix of the other versions described in this topic, although very close to the one of @WINEDS (thanks for the hints).  

Everything seems to work so far.

Installed using rockchip dev tools, as advised.

To enable Bluetooth I have used this small overlay in  /boot/overlay-user/ (which enables SPDIF as well):

/dts-v1/;
/plugin/;

/*   &{/serial@fe650000}  */
   &uart1 {
            status = "okay";
            dma-names = "tx\0rx";
            bluetooth {
                status = "disabled";
            };
        };


    &spdif { 
         clock-names = "mclk\0hclk";
         status="okay";     
    };

 

The followings are the drivers used for wifi-bluetooth

To re-enable display in Linux 6.12  another small overlay is required: (the display itself it is not scrolling and available at: /sys/class/leds/display/value )

/dts-v1/;
/plugin/;


 &{/i2c-aux-display} {

            compatible = "i2c-gpio";
            #address-cells = <0x01>;
            #size-cells = <0x00>;

            display@24 {
                compatible = "fdhisi,fd6551";
                reg = <0x24>;
                #address-cells = <0x01>;
                #size-cells = <0x00>;

                tm16xx,digits = [04 03 02 01];
                tm16xx,segment-mapping = [00 01 02 03 04 05 06];

                led@0,0 { reg = <0x00 0x00>; function = "alarm"; };
                led@0,1 { reg = <0x00 0x01>; function = "usb"; linux,default-trigger = "usb-host"; };
                led@0,2 { reg = <0x00 0x02>; function = "pause"; linux,default-trigger = "mmc2"; };
                led@0,3 { reg = <0x00 0x03>; function = "play"; linux,default-trigger = "mmc0"; };
                led@0,4 { reg = <0x00 0x04>; function = "colon"; };
                led@0,5 { reg = <0x00 0x05>; function = "lan"; linux,default-trigger = "stmmac-0:00:link"; };
                led@0,6 { reg = <0x00 0x06>; function = "wlan"; linux,default-trigger = "mmc1"; };

                digits { status = "disabled"; };
                leds { status = "disabled"; };

           };
 };

Could anyone advise the simple example on how to play media files using hardware decoding on VPU?

I use actual version of Armbian with Edge kernel

user@h96-tvbox-3566:~$ uname -a
Linux h96-tvbox-3566 6.18.0-rc7-edge-rockchip64 #1 SMP PREEMPT Sun Nov 23 22:53:16 UTC 2025 aarch64 aarch64 aarch64 GNU/Linux

and seems that rkvdec is available

user@h96-tvbox-3566:~$ v4l2-ctl --list-devices
rockchip,rk3328-vpu-dec (platform:fdea0000.video-codec):
        /dev/video2
        /dev/media1

rockchip,rk3568-vepu-enc (platform:fdee0000.video-codec):
        /dev/video3
        /dev/media2

rockchip-rga (platform:rga):
        /dev/video1

rkvdec (platform:rkvdec):
        /dev/video0
        /dev/media0

 

then I've installed MPV player from Armbian repository using apt command, but it seems that it doesn't support hardware decoding. I tried to use different hwdec options (rkvdec, rga, rkmpp, hantro....) but got "Unsupported hwdec" each time.
