radxa zero support? (urgent)

[qNnOtTk]

how do I make it work on the radxa zero? board os: Linux radxa-zero 5.10.69-10-amlogic-g617a45dd0fce aarch64 GNU/Linux Debian 10 SoC is amlogic s905y2 what I tried to get the display running is I used the adafruit18.dts script but modified it a little `/*

• Device Tree overlay for Adafruit 1.8" TFT LCD with ST7735R chip 160x128 */

/dts-v1/; /plugin/;

/ { compatible = "radxa,zero", "amlogic,g12a";

    fragment@0 {
            target = <&spidev0>;
            __overlay__ {
                    status = "disabled";
            };
    };

    fragment@1 {
            target = <&spi0>;
            __overlay__ {
                    /* needed to avoid dtc warning */
                    #address-cells = <1>;
                    #size-cells = <0>;
                    status = "okay";

                    af18: adafruit18@0 {
                            compatible = "fbtft,adafruit18";
                            reg = <0>;
                            pinctrl-names = "default";
                            spi-max-frequency = <40000000>;
                            rotate = <90>;
                            buswidth = <8>;
                            fps = <50>;
                            height = <130>;
                            width = <130>;
                            reset-gpios = <&gpio_x 8 1>;
                            dc-gpios = <&gpio_x 10 0>; #same thing as below
                            led-gpios = <&gpio_x 9 0>; #here i changed from gpio 25 to gpio_x 9, i referred to the gpio pin names here https://wiki.radxa.com/Zero/hardware/gpio
                            debug = <0>;
                    };
            };
    };

    __overrides__ {
            green = <&af18>, "compatible=fbtft,adafruit18_green";
            speed     = <&af18>,"spi-max-frequency:0";
            rotate    = <&af18>,"rotate:0";
            fps       = <&af18>,"fps:0";
            bgr       = <&af18>,"bgr?";
            debug     = <&af18>,"debug:0";
            dc_pin    = <&af18>,"dc-gpios:4";
            reset_pin = <&af18>,"reset-gpios:4";
            led_pin   = <&af18>,"led-gpios:4";
    };

};

` Can anyone help me make this display work on this board please?

That compatible won't work, should be compatible = "sitronix,st7735r";

[queld]

I'll try that when i get home, but that's not the problem,the only parts I changed for this code is compatible = "radxa,zero", "amlogic,g12a"; and reset-gpios = <&gpio_x 8 1>; dc-gpios = <&gpio_x 10 0>; led-gpios = <&gpio_x 9 0>; When I get home I can send the code I used on the RPI, the one in the original post is the one I used on the radxa zero

Now I know what those strange compatibles are, rpi linux has patched up the st7735r driver with variants from the now gone fbtft_device: https://github.com/raspberrypi/linux/commit/1b84376666847a19a33e562a3bc25b0e0d259b26
