Write the image to a USB drive, then boot the system from the USB drive, format EMMC after system startup, and then enter UMS to re burn.

git checkout 6.1.75
./build-kernel.sh arm64

The deb file will be generated in the higher-level directory of the code and copied to the machine for installation.

@petersen77
The compilation of Mesa is closely related to the DRM version, so pay attention to the version.

@Momo-0
TYPEC is only related to DTS, and the main issue with the sound card is Tinymix configuration.

@Momo-0
The official default configuration of ARMBIN's loadaddr and optee conflicts and needs to be modified to 0x200000

@petersen77
Compile and install mesa24 or higher versions.

• Install the motion package

sudo apt install motion -y

• Insert USB camera and recognize video node normally

admin@cp2b:~$ ls /dev/ |grep video
video0
video1

• Modify the following configurations

framerate 60  //Change frame rate to 100
stream_maxrate 60 //Add configuration
webcontrol_localhost off  //Support remote control
stream_localhost off off //Support remote stream

• Increase services

sudo systemctl start motion
sudo systemctl enable motion
sudo reboot

• Accessing the camera, please note that HTTPS is not supported

@petersen77
The rc.local script actually only performs simple scaling operations, which can be implemented anywhere in the system, such as creating a service yourself.
Regarding GPU issues, it is necessary to compile and install the latest version of Mesa by oneself.

Installation Based on Physical Machine

sudo apt update
curl -fsSL https://deb.nodesource.com/setup_20.x | sudo -E bash - &&\
sudo apt-get install -y nodejs
sudo apt install  npm
sudo npm install -g --unsafe-perm node-red

Based on Docker

mkdir /home/iotts/node_red
cd /home/iotts/
sudo chmod 777 node_red  
sudo docker run -d --restart always -p 1880:1880/tcp -v /home/iotts/node_red:/data --name nodered nodered/node-red

Start on Boot

• Create a service

sudo nano /etc/systemd/system/node-red.service

• Paste the following content in the editor:

[Unit]
Description=Node-RED
After=network.target

[Service]
ExecStart=/usr/bin/node /usr/bin/node-red
User=sa

[Install]
WantedBy=multi-user.target

• Reload the systemd manager configuration to make the new service effective:

sudo systemctl daemon-reload

• Start the Node RED service and set it to boot up automatically:

sudo systemctl start node-red
sudo systemctl enable node-red

• Check the status of Node RED service:

sudo systemctl status node-red

Set user password

• Open the settings. js file

vim /home/admin/.node-red/settings.js

• To modify the content of CredentialSecret, you need to set a key, not a login password. Save and exit.
  

• Restart Ubuntu

sudo reboot

• Generate username and password, using admin as an example here

node-red admin hash-pw

admin@cp2b:~$ node-red admin hash-pw
Password: $2y$08$cUm1LgtBnDt.b.az4IiLeuPCNb0LFv.hbnd71OWwd94j.GMF/WVnW

• Open the settings. js file, modify the content of adminAuth, and copy the string from earlier. Save and exit.
  

• Restart Ubuntu

@petersen77
According to the following steps, theoretically all distribution versions can be launched:

1. Mount the Coolpi style image file in a Linux environment (the image file includes 2 partitions, mount the second partition), back up /etc/rc/local, and then delete all contents.
2. Copy the new file system (such as arch) directory to the mount directory.
3. Unzip modules. tar. gz（The file is in the first partition of the Coolpi image） to the /lib directory
4. Copy /etc/rc.local to the new file system/etc directory
5. Mirror flashing to machine startup.

• Install hostapd (requires internet connection)

sudo apt install hostapd

• Enable encryption mode for 2.4G hotspot
  Enter the following content, using the 11ax wireless standard, encryption method WPA-PSK, ssid as hotspot name, and wpa_passphrase as custom password, all of which can be modified

vi /etc/hostapd.conf

interface=wlan0
driver=nl80211
ctrl_interface_group=0
ctrl_interface=/var/run/hostapd
beacon_int=100
ssid=aic_ax_2.4G
country_code=CN
channel=6
hw_mode=g
ieee80211n=1
ieee80211ac=1
ieee80211ax=1
ht_capab=[HT20][SHORT-GI-20][HT40-][HT40+][SHORT-GI-40]
wmm_enabled=1
he_basic_mcs_nss_set=65534
auth_algs=3
wpa=3
wpa_passphrase=1234567890
wpa_key_mgmt=WPA-PSK
wpa_pairwise=CCMP
rsn_pairwise=CCMP

• Add Address Resolution

 vi /etc/dnsmasq.conf

# Only monitor the AP interface
interface=wlan0
bind-interfaces

# DHCP configuration
dhcp-range=192.168.11.2,192.168.11.20,255.255.255.0,24h
dhcp-option=3,192.168.11.1
dhcp-option=6,8.8.8.8,114.114.114.114
resolv-file=/etc/dnsmasq/resolv.conf

• Create /etc/dnsmasq/resol.conf

mkdir -p /etc/dnsmasq
vi /etc/dnsmasq/resolv.conf

Enter the following content

nameserver 8.8.8.8
nameserver 8.8.4.4

• Create script to enable AP mode

vi /usr/bin/start_wifi_ap.sh

Enter the following content

#!/bin/bash
#
## Search for network interfaces starting with wlan
WIFI_IFACE=wlan0

# Configure IP address
ifconfig $WIFI_IFACE 192.168.11.1 up

# Start hostapd
hostapd /etc/hostapd.conf -dd &

# Start dnsmasq
touch /var/lib/misc/udhcp.leases
dnsmasq -i $WIFI_IFACE -C /etc/dnsmasq.conf &

echo "AIC WiFi AP started on interface $WIFI_IFACE"

Modify permissions

chmod a+x /usr/bin/start_wifi_ap.sh

• Add IP forwarding rules

sudo sh -c "echo 1 > /proc/sys/net/ipv4/ip_forward"

• Edit /etc/sysctl.d/10-network-security.conf and add the following line

net.ipv4.ip_forward=1

• Effective operation

sudo sysctl -p

• Download Iptables (requires internet connection, can be skipped if installed at the top)

sudo apt update
sudo apt install iptables-persistent
sudo apt install iptables

• Add rule

sudo update-alternatives --set iptables /usr/sbin/iptables-legacy
sudo update-alternatives --set ip6tables /usr/sbin/ip6tables-legacy
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i wlan0 -o eth0 -j ACCEPT
sudo iptables -A FORWARD -i eth0 -o wlan0 -m state --state RELATED,ESTABLISHED -j ACCEPT

• Afterwards, every time the AP is turned on, it can be started through the startw_ifi_ip.sh script. If you want it to start automatically, please add a service to implement it yourself.

admin@cp2b:~$ sudo start_wifi_ap.sh 
[sudo] password for admin: 
AIC WiFi AP started on interface wlan0

确认loader升级到最新版本，然后系统镜像通过etcher刷入TF卡，默认的启动顺序是USB TF卡 EMMC。

@mainbord
Use the following command to generate a deb file and then install it.

./build-kernel.sh arm64

In the process of user development, after building their own application, it is usually necessary to back up the file system and then copy it to other machines. The following provides backup scripts and operation methods:

• list itemIt is best to use a file system with a capacity greater than twice that of a USB flash drive, for example, if the file system is 4GB, choose an 8GB capacity USB flash drive and format it in NTFS format.
  * Copy the script file to a USB drive.
  * Insert the USB drive into the USB port of the CP1B machine and turn it on.
  * Use the following command to mount a USB drive to the/mnt directory.
  sudo mount /dev/sda1 /mnt
  * Enter the/mnt directory and execute the script.
  cd /mnt sudo ./backup-cp1b.sh
  * After the script is executed, the root directory of the USB drive will generate a * * *. img file, which can be used to replace the rootfs. img file in the compressed image file.

需要mesa更新到24.0以上。可以使用百度网盘最新ubuntu24.04镜像。

@ytfycy
CM5是ARM架构的机器，不能支持X86架构的镜像文件。
如需安装ARM64架构的UBUNTU22.04镜像，请参考如下文档：

在国内使用 Docker 拉取镜像时，经常会遇到镜像源无法访问的问题，为了解决这一问题，下面将介绍如何配置 DaoCloud 镜像源，确保在国内快速稳定的下载镜像。

通过上述步骤新安装的 Docker 一般不存在文件/etc/docker/daemon.json，没关系，我们直接使用vim /etc/docker/daemon.json进行创建并编辑，输入以下内容：

{
    "registry-mirrors": [
        "https://docker.m.daocloud.io"
    ]
}

保存文件后重启 Docker 服务，新的镜像源即可生效：

systemctl daemon-reload
systemctl restart docker
