am335x的tilcdc驱动显示问题-TI中文支持网

最近使用am335x驱动友达的12寸触摸屏 auo G121XN01，出现无法正常显示图像的问题，使用的是ti-processor-sdk-linux-am335x-evm-06.01.00.08，白色字是登录输出，图片是自己编写的qt程序，图片显示不全，而且颜色（图片为蓝底）显示不对，以下是设备树的信息

panel {

compatible = "ti,tilcdc,panel";

status = "okay";

pinctrl-names = "default";

pinctrl-0 = <&lcd_pins_s0>;

panel-info {

ac-bias = <255>;

ac-bias-intrpt = <0>;

dma-burst-sz = <16>;

bpp = <32>;

fdd = <0x80>;

sync-edge = <0>;

sync-ctrl = <1>;

raster-order = <0>;

fifo-th = <0>;

};

display-timings {

800x480p62 {

clock-frequency = <60000000>;

hactive = <1024>;

vactive = <768>;

hfront-porch = <39>;

hback-porch = <39>;

hsync-len = <47>;

vback-porch = <29>;

vfront-porch = <13>;

vsync-len = <2>;

hsync-active = <1>;

vsync-active = <1>;

};

以下是启动log，出现了tilcdc 4830e000.lcdc: no encoders/connectors found 问题

请看一下下面勘误表上的3.1.1 LCD: Color Assignments of LCD_DATA Terminals，颜色显示不对是不是这个问题引起的。

颜色显示没有问题了，但图片显示不全，图片周围还是黑色边框

user6350786：

系统启动时显示 tilcdc 4830e000.lcdc: tilcdc_crtc_irq(0x00000104): Sync lost

Shine：

请问具体怎么显示不全？
