RGB LCD does not display

[ZLiu.3]

My rgb lcd screen does not display。

​

My board is based on the STM32MP153AAA3 design, using a separate power supply.

​

This is my schematic diagram

​This is the timing of the LCD

​ This is the LCD device tree

 

​This is some panel-simple driver code

​Here are some boot logs

 

Looking forward to your response!

i have solved it.

​

The ltdc node has a problem：

&ltdc {
 pinctrl-names = "default", "sleep";
 status = "okay";
 pinctrl-0 = <&ltdc_pins_b>;
 pinctrl-1 = <&ltdc_pins_sleep_b>;
 port {
 #address-cells = <1>;
 #size-cells = <0>;
 
 ltdc_ep0_out: endpoint@0 {
 reg = <0>;
 remote-endpoint = <&rgb_8_panel_in>;
 };
 };
};
