hello all,
i am working on custom board based on imx7d SOC, in my custom board display is not working,
following are the things i have tried,
i have changed following entry in device tree:
&lcdif {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_lcdif_dat
&pinctrl_lcdif_ctrl>;
display = <&display0>;
disp-dev = "lcd";
status = "okay";
display0: lcd-display {
bits-per-pixel = <32>;
bus-width = <24>;
display-timings {
native-mode = <&timing_vga>;
timing_vga: 800x480 {
clock-frequency = <25175000>;
hactive = <800>;
vactive = <480>;
hback-porch = <40>;
hfront-porch = <24>;
vback-porch = <32>;
vfront-porch = <11>;
hsync-len = <96>;
vsync-len = <2>;
de-active = <1>;
hsync-active = <0>;
vsync-active = <0>;
pixelclk-active = <0>;
};
};
};
};
these changes are according to the lcd specification.
but still i cant get anything i the screen so how can i resolve this problem ?
please guide me .
any help will be greatly appreciated.
