在emmc上安装系统后无限循环开机图片

[planktonzp]

设备: 斐讯n1 原系统: ophub发布的Armbian_24.5.0_amlogic_s905d_noble_6.1.87_server_2024.04.20

安装方式:

1. u盘烧录最新img并创建了data分区存储rootfs.tar.gz
2. mkfs.ext4 -m 0 /dev/mmcblk2p2 作为root分区 挂载到/mnt
3. mkfs.vfat -F 32 /dev/mmcblk2p1 作为boot分区 挂载到/mnt/boot
4. fdisk /dev/mmcblk2p1 修改分区type为EFI
5. 解压rootfs到/mnt下
6. 拷贝uboot+修改uEnv.txt+修改exlinux/exlinux.conf
7. arch-chroot切换根目录后更新系统

解除挂载后重启，拔掉u盘，无限卡在开机图片上，不知道是那一步的问题

串口看日志

我可以用u盘正常进入archlinuxarm 也可以安装armbian到emmc 这个是uboot的问题吗 还没用串口方式查看过.... 是否有相关的资料我先学一下

[planktonzp]

重装armbian到emmc可以正常启动 从u盘启动archlinuxarm也是正常的 仍然不能确认是哪一步骤的问题 armbian更新时选择了使用主线uboot armbian-install -m yes 从启动流程文章里看n1的引导应该是没有被破坏的 我是否需要提供其他内容来方便你确认问题？

希望得到回应 感谢

发串口日志

No log, no problem

我手边并没有焊接工具 因此无法进行拆机并焊接串口查看日志 但是我重装我的系统到armbian 并且使用ampart查看了我的emmc分区内容如下

这些信息是否能够作为参考 我在另一个问题中看到类似的内容#6

[planktonzp]

armbian在n1的emmc中运行正常 看起来是整个引导的流程存在问题 是否是某个autoscript脚本的偏移位需要调整或者确认 我看到了你的文章 但是其中只有一个我看不太懂的Bootloader引导顺序 我无法和我本地的n1进行比对 如何确认我的n1是原厂u-boot还是主线u-boot？

日志不是有报告问题以及怎么修？

拷贝uboot+修改uEnv.txt+修改exlinux/exlinux.conf
