楼主，我们也碰到同样问题了，断电重启有概率会卡在kernel，进不去系统，现在知道的问题是kernel的文件好像坏了，但是不知道为什么，比如断电上电10次可能出现2-3次
kernel的zImage和dtb一般都是只读的 如果是kerenl损坏了可以检查一下是不是你的mtd分区没有设置只读 和 bootargs 是不是ro 而不是rw
如果设置了 可能就不是kernel损坏 可以试试只重新烧录buildroot可不可以恢复 可以的话 那就是跟我的问题一样 建议是再加一个data分区 rootfs设置只读
这样如果损坏了也不会导致无法开机
但是经过我的后续测试 data分区也有概率损坏 然后好像是因为dropbear的原因 把dropbear关了 就没怎么遇到过了
在尝试使用modetest测试图层显示时，只有最后一个图层能够正常显示，如果将分辨率改变，也只有最后一个图层能够显示，并且显示错乱
系统中能够找到/dev/dri/card0设备
并且fb0能够正常显示
将drm log打开后 内核开机log如下

感谢@4610大佬的解答
目前进度 成功将rootfs分区挂载成只读 新建立一个可读写分区用于修改和存放文件。
目前测试wifi、dropbear都没有问题
由于根目录只读，dropbear无法创建密钥，需要链接一个路径到/etc/dropbear才能正常使用
再看看是否还会出现异常掉电系统损坏情况
再次感谢@4610大佬的解答
@4610
感谢大佬
想问一下第二个分区是否也是挂载成ubi卷呢？如果是两个分区都挂载成ubi卷，那第二个分区如果损坏了 是否也会影响到开机。
我的理解是弄两个ubi卷 然后第二个分区是data，我尝试了一下 ，如果把第二个分区也以ubi卷的方式去挂载，我没有烧录那个分区的数据 他也是启动不起来
不知道我理解的对不对 大佬可以详细讲一下嘛
划两个ubifs分区，root只读，会改动的放另外一个里
感谢大佬的建议
具体是将整个根目录只读嘛？这样会不会影响wifi或者一些别的操作？
基本没啥好办法，只能重刷
没办法解决嘛，他好频繁出现，也不知道有没有什么补丁
虽然ubifs系统本身对掉电容忍度很差，但这也太差了
每次重刷buildroot又要个五六分钟
如标题环境，在使用spi nand flash存储时，如果系统在运行时 发送异常掉电情况，有概率会出现ubifs根目录损坏导致无法开机的情况

[ 5.206801] Rebooting in 5 seconds..内核的bootargs：
bootargs = "console=ttyS0,115200 earlyprintk panic=5 rootwait mtdparts=spi0.0:1M(uboot)ro,128k(dtb)ro,5M(kernel)ro,-(rootfs) ubi.mtd=3 root=ubi0:rootfs rw rootflags=sync rootfstype=ubifs";之前没有加入rootflags=sync ，尝试以sync挂载ubifs还是会出现这种情况，一般在异常掉电时才有概率出现，必须重新烧录才能恢复
可以通过修改kconfig文件该选项对V3S的的依赖项，使得选择V3S的时候“Enable graphical uboot console on HDMI, LCD or VGA“选项显示。原依赖项MACH_SUN8I_V3S中的取反符号去掉即可。
楼主问题解决了吗？
尝试过这种方法，这样操作没有任何效果，编译可以通过，但是跑起来的时候屏幕还是点不亮
现在用别的办法解决了，根据 https://github.com/u-boot/u-boot/compare/master...mcerveny:u-boot:simplefb_v3s_v2 打差异补丁点亮了屏幕，不过这种方法可以将屏幕参数传递给kernel，但是uboot本身启动时无法点亮屏幕，不是一个特别完美的方法。
因为要使用spi nand flash启动系统 用了2022.04版本的uboot，但是因为ARM architecture里没有Enable graphical uboot console on HDMI, LCD or VGA 选项，经过一顿折腾 发现kconfig中 当选用v3s就会关闭Enable graphical uboot console on HDMI, LCD or VGA 选项 修改kconfig后，勾选 配置后，只能点亮背光，现在开机白屏，该怎么驱动LCD
