背景

我在做 aosp14 移植，目前用 uboot2025.01-rc1,linux 5.10 现在能运行内核，内核能调用 android 的第一阶段 init （ bl 把 init_boot+vendor_boot 的 ramdisk 读取到内存后传递给内核，内核把 initramfs unpack 到 rootfs ），metadata 分区 16MB ，刷入了生成的空白 ext4 文件系统镜像。

问题

第一阶段 init 可以运行，但是只能运行一部分，大概运行到

if (!fsm) {
            fsm = CreateFirstStageMount(cmdline);
        }

设备就会自动重启，cmdline 加了 init_fatal_panic=true 但是没任何 panic 还是 reboot 到 bootloader 。如果 fstab 里不写 metadata 会跳过 metadata ，此时串口日志显示创建了几个逻辑分区给 system 、vendor 等，但是也会突然自动重启。

所有串口日志最后一条的下一条就是设备重启的日志：rk860-regulator 1-0042: rk860..... reset等，无参考价值。串口日志（ fstab 有 metadata ）：
