for knaerzche , I've finally discovered what not works on my box with your images. This is my dts coded on top of an rk3228b box dts.

#include "rk3228b-box.dtsi"

/ {
    model = "RK3228b V88 (mx4vr-v01 board)";

    leds {
                compatible = "gpio-leds";

                led_blue {
                        gpios = <&gpio1 RK_PA7 GPIO_ACTIVE_LOW>;
                        default-state = "on";
                };

                led_red {
                        gpios = <&gpio3 RK_PC5 GPIO_ACTIVE_LOW>;
                        default-state = "off";
                        linux,default-trigger = "rc-feedback";
                };
        };

};

&dmc {
    status = "disabled";
};

&sdmmc {
        /delete-property/ sd-uhs-sdr50;
        /delete-property/ sd-uhs-sdr104;
};

I've disabled dmc and some sdmmc commands that hangs the sd controller.

I've a similar board (mine is mx4vr-v01). The image that works for me is the one for "MXQ 4K Pro, RK3228A, DDR3".

Probably you need to replace kernel dtb because in my case the image boots, turn on blue led but freeze with blank screen.

So I've extracted the dtb from my android firmware and used that.

Thanks for the explanation. If I understand correctly Netflix and others, legally allow viewing HD contents on linux. So I lowered the resolution, (to avoid useless upscaling), and the frame dropping disappear.

For me it's better than nothings

After several days of tests and experiments, considering the architecture and the price of the box, the hardware features are excellent.

Some emulators and local streaming are fine.

Paid streaming addons work, but unfortunately, hardware acceleration for DRM content seems to be impossible.(h264 Hardware decoding? · Issue #207 · peak3d/inputstream.adaptive · GitHub)

Hi knaerzche  thanks for your hard work. I've finally run some sort of linux in my box

I'm not sure what is my model but seems to be a Shishion V88 plus with rockchip 3228, 1Gb ram 8Gb rom and ssv6501p wifi card.

Your images for rk3228 works for me only with the dtb extracted from my android firmware, so I'll share the decompiled dtb in case you what to add this device.

I have one question, and some tips

Do you have the source code of trust images for rk3228, or you have found it somewhere!?

Next the tips, with "noop" scheduler and "performance" cpufreq scaling governor (now is interactive by default that is good for smartphones) the box run better.

Thanks
