      V2.0版本SDK编译打包启动后输出下面日志(只截取了LCD初始化部分):

      由于这段日志

      [    0.225433] [DISP] Fb_copy_boot_fb,line:1510:
      [    0.225439] src_height(1280) > dst_height(480),please cut the height
      

      初始化代码出现异常就没有加载st7701s驱动,出现异常的原因是:(文件是:lichee/linux-5.4/drivers/video/fbdev/sunxi/disp2/disp/dev_fb.c,那几行日志是我加的,上面截取的日志里也能看到)

      099c2168-a0c4-4900-9704-60f1b45f0d7b-image.png

      从设备树中 disp@5000000 节点获取到了 boot_fb0 节点,boot_fb0 节点内容是 boot_fb0 = 000000005eb13000,320,500,20,c80,0,0,320,500,320和500都是16进制,转换为10进制分别为800和1280,我在设备树中lcd设置的宽高都是480,这个地方有个判断:
      1a04c734-cd02-4cf4-bf33-fbdd99450fb1-image.png
      所以出现了 src_height(1280) > dst_height(480),please cut the height

      想请教下各位大佬这个 boot_fb0 是在哪配置的(我的设备树里找不到这个节点),应该怎么修改呀?

        @dyd2022 这是开机logo的大小,你替换一张开机logo和你lcd匹配的分辨率即可

          @anruliu 在 请教关于D1-H_Tina_open V2.0的LCD驱动未加载问题 中说:

          @dyd2022 这是开机logo的大小,你替换一张开机logo和你lcd匹配的分辨率即可

          感谢大佬

          原因找到了,问题有四个:
          1、这个 boot_fb0 其实是u-boot的设备树 lcd 节点,我只改了内核的设备树,需要把u-boot的设备树 disp和lcd节点设置的和内核的一样
          kernel 板级配置:device/config/chips/d1-h/configs/nezha/linux-5.4/board.dts
          uboot 板级配置:device/config/chips/d1-h/configs/nezha/uboot-board.dts
          2、u-boot需要配置支持st7701s驱动:
          228ac2f4-3365-448d-a41f-608b71318821-image.png
          配置文件路径:lichee/brandy-2.0/u-boot-2018/configs/sun20iw1p1_defconfig
          3、修改bootlogo.bmp图片文件,源文件是一个800x1280的图片,需要替换成我的480x480文件(图片尺寸太大内核日志会显示错误信息),文件路径:device/config/chips/d1-h/configs/nezha/configs
          4、修改st7701s的驱动初始化设置,一般买屏幕卖家会提供初始化代码,修改成自己屏幕的初始化设置
          fbee78a9-0210-4449-ae84-09d2ea1149ed-image.png

          我开始在内核中加了很多屏幕初始化日志,但是一大部分没打印,我以为是内核的驱动没加载,后来发现好像是u-boot做了初始化内核就不做初始化了,内核直接把u-boot的framebuffer复制了一份就接着显示了,系统起来之后输入 cat /dev/random > /dev/fb0 会出现雪花屏,不知道我的理解对不对,要是不对欢迎大佬指正😀

          还有点小问题就是启动过程中屏幕会闪一下,看另一个大佬说的是因为内核复制完u-boot的framebuffer后还没来得及显示,u-boot就把显示关了,所以会闪一下,还请大佬们指点下这个咋改。

            @dyd2022 请问一下,您uboot可以显示logo吗? 我内核可以驱动lcd 并显示了,移植到uboot,设备树设置了跟内核一样,图片也换了相同分辨率的,但是uboot还是没有显示logo,大概是什么问题呢?大佬可以贴下您uboot 的设备树文件吗?
