I am facing an issue connecting raystartft display (model:-RFE430W-AWW-DNS) to toradex evaluation board(colibri imx6ull 1GB IT).I created a .dts file(timing_raystar_tft.dts) based on the raystar display`s specification.
/dts-v1/;
/plugin/;
/ {
compatible = "toradex,colibri-imx6ull-emmc";
backlight {
status = "okay";
};
lcdif {
status = "okay";
};
raystar_display {
compatible = "raystar,tft-display";
data-mapping = "RGB-24";
width-mm = <105>;
height-mm = <67>;
width = <480>;
height = <272>;
bits-per-pixel = <24>;
bus-width = <24>;
clock-frequency = <9000000>;
display-timings {
native-mode = <&timing_raystar_tft>;
};
};
timing_raystar_tft: timing {
hactive = <480>;
vactive = <272>;
hback-porch = <43>;
hfront-porch = <8>;
vback-porch = <12>;
vfront-porch = <8>;
hsync-len = <4>;
vsync-len = <4>;
hsync-active = <1>;
vsync-active = <1>;
pixelclk-active = <1>;
};
pwm4: pwm {
status = "okay";
};
};
I compiled the .dts file into a .dtbo file (timing_raystar_tft.dtbo) and transferred it to the Toradex board.
torizon@colibri-imx6ull-emmc-07201405:~$ ls
timing_raystar_tft.dtbo
Following Toradex’s instructions, I added the overlay (timing_raystar_tft.dtbo) to
torizon@colibri-imx6ull-emmc-07201405:~$ ls /sysroot/boot/ostree/torizon-aa566e8630fda3cc14c3697cf8d4e5d8e0106402654c028e914c11578125f784/dtb/overlays

It shows no changes to display…
