用的是800x1280的mipi屏,驱动用的是tft08006,用示波器测信号,发现数据线都有正常信号,时钟线却没有正常信号,用打印信息看初始化代码,也有正常使能时钟,请问这到底是哪里的问题?

回复: ubifs卷挂载问题
@y97788 在 ubifs卷挂载问题 中说:
ubiupdatevol /dev/ubi0_1 boot-resource.fex
这样可以修改整个卷的数据,但是如何修改boot-resource.fex里bootlogo.bmp,或者如何将新的bootlogo.bmp打包生成boot-resource.fex文件,然后再用上面命令来更新卷数据你好,我也碰到了这个问题,请问你解决了吗

100ask-t113-pro lvds调试问题
RGB屏是可以正常显示的,但是配置lvds设备树时,却显示异常,用fbshow写图片也无法显示
设备树lvds配置如下:
&lcd0 {
lcd_used = <1>;lcd_driver_name = "default_lcd"; lcd_backlight = <50>; lcd_if = <3>; lcd_x = <800>; lcd_y = <600>; lcd_width = <108>; lcd_height = <94>; lcd_dclk_freq = <39>; lcd_pwm_used = <1>; lcd_pwm_ch = <7>; lcd_pwm_freq = <50000>; lcd_pwm_pol = <0>; lcd_hbp = <88>; lcd_ht = <1024>; lcd_hspw = <64>; lcd_vbp = <15>; lcd_vt = <625>; lcd_vspw = <6>; lcd_lvds_if = <0>; lcd_lvds_colordepth = <0>; lcd_lvds_mode = <1>; lcd_frm = <0>; lcd_io_phase = <0x0000>; lcd_gamma_en = <0>; lcd_bright_curve_en = <0>; lcd_cmap_en = <0>; deu_mode = <0>; lcdgamma4iep = <22>; smart_color = <90>; pinctrl-0 = <&lvds0_pins_a>; pinctrl-1 = <&lvds0_pins_b>;
};
请问是设备树配置出错了吗?
显示异常的现象:
用fbshow显示显示png图片不能显示,但过会儿屏幕有蓝色
使用接口自带 colorbar
