Hello! Has anyone tried to get work a dual channel LVDS display on the aio-rk3288j with firefly sdk? I tried to connect single channel display and it's work perfect, but when I connected dual channel display I have no picture. Display timings is right, on mainline kernel I have normal picture but not on firefly kernel.
dts:
...
&lvds_panel {
status = "okay";
compatible ="simple-panel";
power-supply = <&vcc_lcd>;
backlight = <&backlight>;
enable-delay-ms = <10>;
rockchip,data-mapping = "vesa";
rockchip,data-width = <24>;
rockchip,output = "duallvds";
rockchip,panel = <&lvds_panel>;
display-timings {
native-mode = <&timing0>;
timing0: timing0 {
clock-frequency = <122000000>;
hactive = <1920>;
vactive = <720>;
hback-porch = <0>;
hfront-porch = <0>;
vback-porch = <0>;
vfront-porch = <0>;
hsync-len = <480>;
vsync-len = <120>;
hsync-active = <0>;
vsync-active = <0>;
de-active = <0>;
pixelclk-active = <0>;
};
};
};
