Ubuntu22.04挂载扩容Cool-PI-4B（eMMC 32GB）

Ubuntu22.04 默认更新系统后，只有8GB空间，以下进行扩容，使用100%空间

• 更新前的容量如下：

ubuntu@coolpi:~$ df -h
Filesystem      Size  Used Avail Use% Mounted on
tmpfs           372M  4.0M  368M   2% /run
/dev/mmcblk0p2  6.4G  5.4G  704M  89% /
tmpfs           1.9G     0  1.9G   0% /dev/shm
tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           372M  124K  372M   1% /run/user/1000

ubuntu@coolpi:~$ sudo fdisk -l
[sudo] password for ubuntu:

/dev/mmcblk0p2      616448 14335999 13719552  6.5G 83 Linux

• 采用parted命令进行扩容

ubuntu@coolpi:~$ sudo parted /dev/mmcblk0 
GNU Parted 3.4
Using /dev/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.

• 输入resizepart进行重新分配空间，并退出

(parted) resizepart                                                       
Partition number? 2                                                       
Warning: Partition /dev/mmcblk0p2 is being used. Are you sure you want to continue?
Yes/No? YES                                                               
End?  [7340MB]? 100% 
(parted) quit 

• 重启系统

ubuntu@coolpi:~$ sudo reboot

• 查看更新后的容量

ubuntu@coolpi:~$ df -h

Pi 5 Compute Module

CM5 Datasheet.pdf

The SOM of RK3588 (CM5) takes the form of core board and bottom board. The core board is connected to the bottom board through the standard interface of SODIMM 314P MXM3.0, which can form a complete industrial motherboard. With abundant expansion interfaces, it supports the expansion of multiple types of peripheral devices, greatly showing the high performance advantages of RK3588-ultralow power consumption and super performance. It can be directly used in a variety of intelligent product development, accelerating the product landing.

Carrier board（MiniPC Product）

CP-3588BX0 Datasheet.pdf

CM5 can be customized with the bottom board, which has some rich interfaces, supporting multiple hard disk, gigabit network, WiFi6, 5G/4G expansion and a variety of video input and output; Meanwhile, it can provide many power supply modes and support for multiple operating systems; It can be applied to MINI PC, ARM PC, edge computing, cloud server, intelligent NVR and other fields as well.

@Wario Except that the miniDP port is different from the micro HDMI of raspberry pi4b, the others are the same, including PoE
