Dear all,
i’m working with the following configuration:
Apalis iMX8QM 4GB WB IT V1.1D
Ixora Carrier Board V 1.2A
DISTRO_VERSION = “6.8.2”
DISTRO_CODENAME = “krikstone”
10.1 I am trying to connect LCD(RGB666) to Ixora carrier board.
I want to connect LVDS1_B without using LVDS1_A (single mode)
I am writing device tree overlay:
&ldb2 {
status = "okay";
lvds-channel@0 {
status = "disabled"; // LVDS1_A OFF
};
lvds-channel@1 {
reg = <1>;
fsl,data-mapping = "spwg";
fsl,data-width = <18>;
status = "okay";
port@1 {
reg = <1>;
lvds1b_out: endpoint {
remote-endpoint = <&panel_lvds_in>;
};
};
};
};
&panel_lvds {
data-mapping = "jeida-18"; // jeida-18bit panel
height-mm = <136>;
width-mm = <217>;
status = "okay";
panel-timing {
clock-frequency = <72400000>;
de-active = <1>;
hactive = <1280>;
hback-porch = <88>;
hfront-porch = <72>;
hsync-active = <0>;
hsync-len = <40>;
pixelclk-active = <1>;
vactive = <800>;
vback-porch = <20>;
vfront-porch = <18>;
vsync-active = <0>;
vsync-len = <9>;
};
port {
panel_lvds_in: endpoint {
remote-endpoint = <&lvds1b_out>;
};
};
};
The colors on the LCD appear as follows:
Can you help me to solve this problem?
Best regards,
sjjin
