燒錄鏡像
首先獲取原始鏡像下載站 - Sipeed，解壓后使用PhoenixCard 燒錄到tf卡中。
然后將tf卡插入linux操作系統電腦中。
導出鏡像：sudo dd if=/dev/sdb of=dd.img status=progress
導出dd鏡像后，使用fdisk修改分區信息。
~ fdisk dd.img
Welcome to fdisk (util-linux 2.36.1).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.
#刪除分區5
Command (m for help): d
Partition number (1-5, default 5):
Partition 5 has been deleted.
#刪除分區4
Command (m for help): d
Partition number (1-4, default 4): 4
Partition 4 has been deleted.
#新增分區4
Command (m for help): n
Partition number (4-8, default 4):
#設置起始扇區
First sector (225792-983036, default 227328): 225792
#設置大小300M
Last sector, +/-sectors or +/-size{K,M,G,T,P} (225792-983036, default 983036): +300M
Created a new partition 4 of type 'Linux filesystem' and of size 299.8 MiB.
刪除分區文件系統簽名
Partition #4 contains a ext4 signature.
Do you want to remove the signature? [Y]es/[N]o: y
The signature will be removed by a write command.
#保存文件
Command (m for help): w
The partition table has been altered.
Syncing disks.
制作dd鏡像，將reseze_root.sh,dd.img 放到同一個文件夾中，使用./resize_root.sh ./dd.img ./ v831.img將dd.img轉化為v831.img.xz
(base) ~ ❯ ./resize_root.sh ./dd.img ./ v831.img
input_addr=./dd.img,output_addr=./, name is v831.img
you can run xx.sh <intputaddr> <outputaddr> <name> to specify them or use defult
Such as
dd.sh ./dd.img /root test.img
or
dd.sh ./dd.img

Resizing the filesystem on /dev/loop404p4 to 76736 (4k) blocks.
The filesystem on /dev/loop404p4 is now 76736 (4k) blocks long.
Compressing the mirror takes some time, and you can use <progress -m> at other terminals to see progress
all ok,use xz -dc v831.img.xz |sudo dd of=/dev/sdb bs=1M status=progress oflag=direct to create a tf Startup Disk
(base) ~ ❯
現在得到了v831.img.xz，將該文件移動到windows操作系統電腦上，通過balenaEtcher燒錄到另外一張大一些的卡里。
擴容磁盤大小
將resize.sh導入到Maix Ⅱ dock的根目錄中。
執行resize.sh
擴容root
root@sipeed:/# chmod 777 ./resize.sh
root@sipeed:/# ./resize.sh
your input begin
choose you want do:
1):UDISK
2):root
If you want to view your disks on different platforms,you should do 1
IF you just want expand your root filesystem,do 2
maybe you all want,then do 2 before do 1
You will can't change the size of your root filesystem after you get UDISK
#選擇2，擴容ROOT分區
defult 1):2
You choose 2;
#增加1G
