@jugg 用默认的ubuntu的源，更新下源，如果出问题，多试两次就可以，国内访问不稳定；
sudo apt-get update
sudo apt-get install cmake

亲测可用
固件采用ubuntu22.04版本（eMMC）启动

@jugg 换个源
国内换阿里或者清华的源就好了

@nickliu said in Support PI HQ camera:

PInHQ camera

PlnHQ camera needs to be debugged again. Each camera needs to be adapted. You can send me the corresponding specifications, and we will cooperate with debugging.

@george 不错

@retroman Thanks a lot.

你好，关于coolpi4b的散热是否有推荐可匹配的模块可以用的？是否有相关链接，如有的话，请帮忙推荐下，谢谢。

@tscmga 最大支持1A，如果是5个摄像头，建议外部供电，不然火鸡都烤不熟。

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

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.

请提供下具体硬件环境或者图片，以及测试的方式，预期想达到的目标。

请问编译方法跟桌面版是一样的吗？如不一样，帮忙补充下，谢谢

@大法师 请问是debian11还是Ubuntu20.04，还是Ubuntu22.04的系统镜像版本？

Ubuntu22.04 ( Cool-PI-4B）命令连接WIFI

Ubuntu用命令行连接wifi的方法：

1. 使用ifconfig命令查看当前无线对应的接口名是什么。
2. 再根据无线接口名用iwlist命令去扫描有哪些wifi。

   iwlist wlp2s0 scanning | grep -i ssid
   

3. 最后通过nmcli命令去连接wifi即可。

   nmcli device wifi connect 360WiFi-E75BA4 password 123456 ifname wlp2s0 
   

cat /sys/class/thermal/thermal_zone0/temp

@刘墨苏 还有2GB/8G/16GB版本在优化的路上

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      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
