请教关于D1-H_Tina_open V2.0的LCD驱动未加载问题
-
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）：

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：
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？
这个是我的设备树文件：

@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：
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
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？
