把SD卡从开发板上取下来，然后用读卡器插到电脑的ubuntu22.04虚拟机里面。
SD卡上有两个分区，插入后自动挂载了第二个分区（/media/oct1158/rootfs），但没有自动挂载第一个分区。

目前linux内核和根文件系统都是用的幸狐Luckfox_Nova_SDK_250430编译出来的镜像。
但uboot和设备树dts源文件还是用的rk3308-rock-pi-s开发板的。
设备树dtb二进制文件是把设备树dts源文件放到幸狐的内核目录里面（Z:\Documents\Code\C\Luckfox_Nova_SDK_250430\kernel\arch\arm64\boot\dts\rockchip）编译出来的。

这个uboot没有saveenv命令，无法永久保存bootcmd环境变量，这样的话每次开机都得手动输入命令才行。
但可以在sd卡的efi分区里面建立boot.scr文件，把bootcmd写进去，开机时就能自动读取。

板子开机后，会自动把sd卡的efi分区挂载到/mnt/sdcard目录下。

在电脑的ubuntu22.04虚拟机上创建一个文本文件“bootcmd.txt”，内容如下：
setenv bootargs root=/dev/mmcblk1p2 rootwait rw rootfstype=ext4 console=ttyS0,1500000n8
load mmc 0:1 0x00280000 Image
load mmc 0:1 0x01f00000 luckfox-rk3308b-evb-v10.dtb
booti 0x00280000 - 0x01f00000
注意必须要使用Unix (LF)换行格式。建议在vim编译器里面创建这个文件。

然后把这个文件打包成镜像格式：
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "luckfox_bootcmd" -d bootcmd.txt bootcmd.img

然后用adb push到板子上：
adb push "Z:\Documents\Code\C\test\bootcmd\bootcmd.img" /mnt/sdcard/boot.scr

板子reboot后，就能自动执行我们设定的bootcmd命令，成功开机了。

    aliases {
        mmc0 = &sdmmc;
    };
这样就能把sd卡的第二分区的名称固定为/dev/mmcblk0p2，和uboot里面保持一致。

重新编译内核和设备树：
cd ~/Documents/Code/C/Luckfox_Nova_SDK_250430
./build.sh
将编译好的设备树上传到板子上：
adb push "Z:\Documents\Code\C\Luckfox_Nova_SDK_250430\kernel\arch\arm64\boot\dts\rockchip\luckfox-rk3308b-evb-v10.dtb" /mnt/sdcard

修改bootcmd.txt，把第一行的/dev/mmcblk1p2改成/dev/mmcblk0p2：
setenv bootargs root=/dev/mmcblk0p2 rootwait rw rootfstype=ext4 console=ttyS0,1500000n8
打包成镜像：
mkimage -A arm -O linux -T script -C none -a 0 -e 0 -n "luckfox_bootcmd" -d bootcmd.txt bootcmd.img
上传到板子上：
adb push "Z:\Documents\Code\C\test\bootcmd\bootcmd.img" /mnt/sdcard/boot.scr
重启板子：
reboot

/dev/mmcblk0p1和/dev/mmcblk0p2同时都被自动挂载到了/mnt/sdcard目录下，所以最好不要用/mnt/sdcard，最好改用/media/sdcard1。
