              @jack_admin 我有个疑问,我用SD卡部署的系统,做好安装盘。然后能在EMMC卡上自动安装吗?
              我理解应该不行吧?SD和EMMC的block名字不一样,还是说安装脚本会自动识别修改

                                    这里这么多镜像
                                    到底怎么用
                                    用哪个

                                    我刷了
                                    42b341fd-f64f-4ee0-876a-0cc8563a44a1-image.png

                                    打不开啊
                                    c3d9a111-3bf2-4070-8a73-6e0be7ad7bc7-image.png

                                    怎么备份?怎么还原?能不能描述清楚
                                    备份是备份emmc的所以还是只备份了文件系统

                                      最近一直在用这个方法,非常太好用太方便了。

                                      我对上面的备份安装放在同一个U盘实现的方法,做了一些改进,通过启动菜单选择 备份 还是 安装, 比每次去改 initrd.img 要方便很多。

                                      步骤1. 编辑 /extlinux/extlinux.conf 如下

                                      menu title Select the boot mode
                                      TIMEOUT 60
                                      default Linux coolpi backup
                                      
                                      label Linux coolpi backup
                                      	kernel /Image
                                      	initrd /initrd-backup.img
                                      	fdt    /rk3588s-cp4.dtb
                                      	append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0
                                      
                                      label Linux coolpi install
                                      	kernel /Image
                                      	initrd /initrd-install.img
                                      	fdt    /rk3588s-cp4.dtb
                                      	append root=LABEL=writable rw rootfstype=ext4 console=ttyS0,115200n81 quiet splash plymouth.ignore-serial-consoles vt.global_cursor_default=1 irqchip.gicv3_pseudo_nmi=0 net.ifnames=0
                                      
                                      

                                      步骤2, 把 install 中的 initrd.img 复制过来,并改名为 initrd-install.img

                                      步骤3, 把 backup 中的 initrd.img 复制过来,并改名为 initrd-backup.img

                                      U盘查到板子上,上电启动。
                                      你局可以看到菜单

                                      Found /extlinux/extlinux.conf

                                      reading /extlinux/extlinux.conf

                                      Select the boot mode
                                      1:	Linux coolpi backup
                                      2:	Linux coolpi install
                                      Enter choice:
                                      

                                      输入1 或 2 回车即可,默认是1, 60秒无输入,则自动启动backup

                                      可以参考 edwardzhou 整理的内容
