使用uEnv.txt配置文件和extlinux/extlinux.conf配置文件的区别是什么？

[KryptonLee]

E900V22C使用您发布的s905l3a镜像，内核5.15，不经修改的话，已经被多人试验证实过无法直接从tf卡启动，启动过程卡在了u-boot无法读取tf卡上。相关日志链接：E900V22C boot from tf

在BOOT分区中创建配置文件extlinux/extlinux.conf，内容如下：

LABEL Armbian
KERNEL /zImage
FDTDIR /dtb
APPEND initrd=/uInitrd root=UUID=ad6b1cca-97d6-47df-9b45-6bf6946cad98 rootflags=data=writeback rw rootfstype=ext4 console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory swapaccount=1

从tf卡启动后可以达到内核启动的步骤，日志如下：

试试这个，指定dtb

[ophub]

extlinux.conf只适合纯主线uboot，例如rockchip或allwinner这些，例如我家云，贝壳云这几个就不需要额外的这个u-boot也可以使用。

只有晶晨是走闭源uboot路线的，所以才会这样，5.10以后的内核不能启动也是晶晨的锅，所以才需要uboot.ext。如果以后5.4停更了，又破解不了u-boot，这真成使用壁垒了，还有锁bl的问题。或许以后有高手能提供其他启动方案。

[KryptonLee]

试过了，结果一样，上面的日志里也显示了加载的dtb是u200的。

append: initrd=/uInitrd root=UUID=ad6b1cca-97d6-47df-9b45-6bf6946cad98 rootflags=data=writeback rw rootfstype=ext4 console=ttyAML0,115200n8 console=tty0 no_console_suspend consoleblank=0 fsck.fix=yes fsck.repair=yes net.ifnames=0 cgroup_enable=cpuset cgroup_memory=1 cgroup_enable=memory swapaccount=1

另一方面，我将ROOTFS分区里的所有文件提换成Arch Linux Arm的ROOTFS文件，将BOOT分区的zImage和uInitrd提换成Arch Linux Arm的kernel和initramfs后，则能够启动Arch Linux Arm并正常使用

[KryptonLee]

忘了说一下我用的Arch Linux Arm内核是5.16.13版本的

[ophub]

启动分几个过程：先是BL1，这是cpu内置的，不依赖外部，然后是BL2，BL31，最后是BL33，BL33是真正编译出来的主线uboot，其它几个都是安卓原厂的。
BL2主要完成内存初始化，也就是acs.bin这个要做的，是从现在的安卓系统里提取的4千字节的内容，只有这个搞定了才能启动。f大上个月在群里指导过Calmact怎么提取测试，不知道目前测试的怎么样了。目前用的这个是通版的，不是这个盒子专用的。
目前推荐你使用usb吧，tf/sd卡有时会有电波干扰和驱动没加载的问题。

[KryptonLee]

谢谢，我也在群里看到F大教的方法了，不过那天之后Calmact好像有其他事，没怎么折腾。我去尝试按照F大的方法提取acs.bin吧，看看能不能搞好。先在这谢谢O大了
