hi,
On the software 4.9.88 software, I have configured the ldb node, and the corresponding configuration is as follows:
#############################################################
#include "fsl-imx8qxp-mek.dts"

model = "Freescale i.MX8QXP MEK";
compatible = "fsl,imx8qxp-mek", "fsl,imx8qxp";
lvds0_panel {
compatible = "boe,av123z7m-n11";
port {
panel_lvds0_in: endpoint {
remote-endpoint = <&lvds0_out>;
};
};
port1{
panel_lvds2_in: endpoint {
remote-endpoint = <&lvds2_out>;
};
};
};
};
&ldb1_phy {
status = "okay";
};
&ldb1 {
split-mode;
/*fsl,dual-channel;*/
status = "okay";
lvds-channel@0 {
fsl,data-mapping = "spwg";
fsl,data-width = <24>;
status = "okay";
primary;
port@1 {

};
};
};
};
&ldb2_phy {

};
&ldb2 {
status = "disabled";
};

But can't drive my screen 1920x720p (the timing I have added to panel-simple.c), the error is reported during initialization, the corresponding error message is as follows:
How can I modify if there is an error in configuring the device tree? I hope to get your help, thank you!
LCD screen manual see attachment。
The above is my configured for single can display properly when an LVDS - 1280 x480, when I change into a double an LVDS screen, don't know how to configure lvds_configure (int lvds_id) function, switch to dual channel an LVDS (SPLIT MODE), how do I configure? In detail how to modify???????????
Before this I know, because I drive screen is single way an LVDS, already all ok.So also add;Now we use double channel an LVDS driver we screen is there is a problem, can't drive.Is more than the TXT attachment tip error.You said the display of the logo I am an LVDS has shown correctly in a single road, but change the dual channel after an LVDS Gao Qingbing cannot display, driver error...
