@(none):[/]:板子采用Quantum，换过H3的其他板子（NanoPi Duo2），结果是一样的（直接将SD卡插入NanoPi Duo2中）一直卡在 Waiting for root device /dev/mmcblk0p2...中
设备树目前是用的sun8i-h3-nanopi-neo-core.dtb。
内核和uboot都是根据友善官方教程Building U-boot and Linux for H5/H3/H2+/zh重新编译的（未修改源码，直接编译），编译器用的Ubuntu2004中apt中的arm-linux-gnueabihf-gcc（尝试过友善提供的，结果一样）
现在一直卡在这里好久了 求大佬帮个忙看看哪里出问题了 感激不尽
推荐还是用原本的这个 https://github.com/CURTLab/LVGLBuilder 貌似还在更新中
这个是修改后的设备树文件sun8i-v3s-blueberrypi-480x272LCD.zip
如题，使用的是荔枝派zero，内核用的蓝莓派的4.18的内核，uboot为荔枝派github上的u-boot-3s-current分支。在uboot中可以正常的显示，证明硬件和连接没有问题。进入linux后整个LCD慢慢就会变白，最后白屏。目前尝试过两种方法，但是找不到问题在哪里：
用framebuffer往fb0里边写数据，但是屏幕什么反应也没有。（这里采用的代码是这里的：https://blog.csdn.net/Bruno_Mars/article/details/94404842）
修改uboot启动参数bootarg为
console=ttyS0,115200 panic=5 rootwait root=/dev/mmcblk0p2 earlyprintk rw vt.global_cursor_default=0 尝试直接从屏幕上输出启动信息，但是仍然没有反映。
示例列表项三。
然后蓝莓派中的设备树中自己根据荔枝派加了framebuffer节点：
chosen {
stdout-path = "serial0:115200n8";
fb0: framebuffer@0 {
compatible = "allwinner,simple-framebuffer", "simple-framebuffer";
allwinner,pipeline = "de0-lcd0";
// clocks = <0x2 0x21 0x2 0x23 0x2 0x3f 0x2 0x40>;
clocks = <&ccu CLK_BUS_TCON0>, <&display_clocks 0>, <&display_clocks 6>, <&ccu CLK_TCON0>;
status = "disabled";
};
};下面是启动的log
