d1-h的lcd显示问题

[lbuque]

sdk: tina v2.0
board: Lichee 86 Panel
lcd: st7701s spi+rgb 408*960

这是要显示的图片

这个是使用 echo /tmp/filename.bmp > /sys/class/disp/disp/attr/capture_dum p 截图出来的图片

ps: 因为截图出来的图像无法上传，所以使用截图代替

这个lcd显示的图片，显示了两张一样的图片

屏幕的初始化代码，使用的是屏厂提供的。

以下是lcd部分的dts

lcd的dts上面还有一个disp的dts，调整fb大小

[lbuque]

@yteraa 以下是我的disp部分dts

&disp {
	disp_init_enable         = <1>;
	disp_mode                = <0>;

	screen0_output_type      = <1>;

	screen1_output_type      = <3>;
	screen1_output_mode      = <10>;

	screen1_output_format    = <0>;
	screen1_output_bits      = <0>;
	screen1_output_eotf      = <4>;
	screen1_output_cs        = <257>;
	screen1_output_dvi_hdmi  = <2>;
	screen1_output_range     = <2>;
	screen1_output_scan      = <0>;
	screen1_output_aspect_ratio = <8>;

	dev0_output_type         = <1>;
	dev0_output_mode         = <4>;
	dev0_screen_id           = <0>;
	dev0_do_hpd              = <0>;

	dev1_output_type         = <4>;
	dev1_output_mode         = <10>;
	dev1_screen_id           = <1>;
	dev1_do_hpd              = <1>;

	def_output_dev           = <0>;
	hdmi_mode_check          = <1>;

	fb0_format               = <0>;
	fb0_width                = <0>;
	fb0_height               = <0>;

	fb1_format               = <0>;
	fb1_width                = <0>;
	fb1_height               = <0>;
	chn_cfg_mode             = <1>;

	disp_para_zone           = <1>;
	/*VCC-LCD*/
/*	dc1sw-supply = <&reg_dc1sw>;*/
	/*VCC-DSI*/
/*	eldo3-supply = <&reg_eldo3>;*/
	/*VCC-PD*/
/*	dcdc1-supply = <&reg_dcdc1>;*/
};

我没有找到这部分dts的相关详细说明

@lbuque 在 d1-h的lcd显示问题 中说：

fb0_width = <0>;
fb0_height = <0>;

如果你需要framebuffer是全屏显示，把fb0的长宽参数填写成你的屏幕分辨率。uboot-dts里面也改一下试试。
