通过emmc启动boot，U盘启动rootfs

[lanlanpy]

大佬你好，我修改了dts的usb模式默认为host，以及修改了cmdline，root参数用的partuuid，内核启动后成功识别了U盘，，但是挂载上rootfs内核就panic了。问了ai也没说具体啥原因导致的。是不是还需要修改initrd呢，还是说dts不是单单改host模式就好

日志晚点上传 好像得移植u-boot引导才能从usb的sd卡启动，开发棒子linux系统的这个大佬之前好像在哪里提到过

这是红米2的u-boot实验分支会玩可以自己想办法移植到棒子上。 https://github.com/joelselvaraj/U-Boot-Redmi2-WT88047

找到原因了。。。是因为之前我在U盘手动创建的rootfs分区，然后挂载的rootfs的img ，把文件复制过去的原因，当时复制文件的时候提示sbin软链文件复制出错，导致init软链到systemd的软链文件丢失了，systemd没法启动。现在启动成功了。。。

重新创建分区后把rootfs dd到U盘的分区后，e2fsck -f /dev/sdb1 后，启动成功了。 lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS sda 8:0 1 14.6G 0 disk └─sda1 8:1 1 14.6G 0 part / sdb 8:16 1 29.3G 0 disk └─sdb1 8:17 1 29.3G 0 part mmcblk0 179:0 0 3.6G 0 disk ├─mmcblk0p1 179:1 0 2K 0 part ├─mmcblk0p2 179:2 0 512K 0 part ├─mmcblk0p3 179:3 0 512K 0 part ├─mmcblk0p4 179:4 0 1M 0 part ├─mmcblk0p5 179:5 0 512K 0 part ├─mmcblk0p6 179:6 0 16K 0 part ├─mmcblk0p7 179:7 0 2M 0 part ├─mmcblk0p8 179:8 0 2M 0 part ├─mmcblk0p9 179:9 0 1K 0 part ├─mmcblk0p10 179:10 0 2M 0 part ├─mmcblk0p11 179:11 0 1M 0 part ├─mmcblk0p12 179:12 0 64M 0 part ├─mmcblk0p13 179:13 0 1M 0 part └─mmcblk0p14 179:14 0 3.3G 0 part mmcblk0boot0 179:32 0 2M 1 disk mmcblk0boot1 179:64 0 2M 1 disk uname -a Linux openstick 5.18.0-handsomehack+ #1 SMP PREEMPT_DYNAMIC Sat Sep 10 15:49:44 UTC 2022 aarch64 GNU/Linux df -TH Filesystem Type Size Used Avail Use% Mounted on udev devtmpfs 179M 0 179M 0% /dev tmpfs tmpfs 41M 1.3M 39M 4% /run /dev/sda1 ext4 16G 828M 14G 6% / tmpfs tmpfs 201M 0 201M 0% /dev/shm tmpfs tmpfs 5.3M 0 5.3M 0% /run/lock tmpfs tmpfs 41M 0 41M 0% /run/user/0
