默认Ubuntu22预装python3.10，暂时与RKNN 本机开发环境不一致，需要单独安装python3.9版本。

step1：增加源

sudo add-apt-repository ppa:deadsnakes/ppa

sudo apt update

sudo apt-mark unhold libexpat1

sudo apt install python3.9* -y

#sudo update-alternatives --list python

#sudo update-alternatives --install /usr/bin/python3 python3  /usr/bin/python3.9 1

#sudo update-alternatives --config python3

setp 2：安装pip3

sudo apt-mark unhold libcurl4

sudo apt install curl -y

curl https://bootstrap.pypa.io/get-pip.py -o get-pip.py

python3.9 get-pip.py

export PATH=/home/ubuntu/.local/bin:$PATH

pip3 -V

pip3 install numpy --upgrade

pip3 install opencv-python

#check opencv
python3.9 -c "import cv2; print(cv2.__version__)"

get-pip.py

step 3：安装rknn toolkit lite2

git clone https://gitee.com/yanyitech/rknpu2.git

sudo cp -arf rknpu2/runtime/RK3588/Linux/librknn_api/aarch64/* /usr/lib/

git clone https://gitee.com/yanyitech/rknn-toolkit2.git

pip3 install rknn-toolkit2/rknn_toolkit_lite2/packages/rknn_toolkit_lite2-1.4.0-cp39-cp39-linux_aarch64.whl

step 4：验证运行环境

cd rknn-toolkit2/rknn_toolkit_lite2/examples/inference_with_lite

ubuntu@coolpi:~/rknn-toolkit2/rknn_toolkit_lite2/examples/inference_with_lite$ python3.9 test.py

Thank you for installing GitLab!
GitLab was unable to detect a valid hostname for your instance.
Please configure a URL for your GitLab instance by setting `external_url`
configuration in /etc/gitlab/gitlab.rb file.
Then, you can start your GitLab instance by running the following command:
  sudo gitlab-ctl reconfigure

For a comprehensive list of configuration options please see the Omnibus GitLab 
readme
https://gitlab.com/gitlab-org/omnibus-gitlab/blob/master/README.md

Notes:
Default admin account has been configured with following details:
Username: root
Password: You didn't opt-in to print initial root password to STDOUT.
Password stored to /etc/gitlab/initial_root_password. This file will be cleaned up in first reconfigure run after 24 hours.

NOTE: Because these credentials might be present in your log files in plain text, it is highly recommended to reset the password following https://docs.gitlab.com/ee/security/reset_user_password.html#reset-your-root-password.

#          1. If provided manually (either via `GITLAB_ROOT_PASSWORD` environment variable or via `gitlab_rails['initial_root_password']` setting in `gitlab.rb`, it was provided before database was seeded for the first time (usually, the first reconfigure run).
#          2. Password hasn't been changed manually, either via UI or via command line.

Check your linux system whether installed docker, if done skip this step.

curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpg

echo   "deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \
    $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

apt update

apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin

Non-root users need to add sudo prefix. This operation is complicated. Now use the following operation to remove it.

sudo groupadd docker
sudo gpasswd -a ${USER} docker
sudo systemctl restart docker
exit or open a new terminal shell

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (arm64v8)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

请同步更新源码

参考如下

sudo apt-mask unhold python3* python3-* libpython3* libexpat1
sudo apt install python3-dev

Debian或Ubuntu镜像使用离线刷机方法，镜像写入完成后，在system-boot分区根目录，新建文件wifi.txt，内容参考如下：

ssid="你要连接的wifi名"
passwd="wifi密码"

插上TF到CoolPi主板，自动连接Wifi

用户基于我们发布是镜像系统，安装软件或进行其他配置之后，如果想备份系统，有很多方法可以实现，我这里提供一个比较简单的思路供大家参考。

前置条件：

假如您手边有一张已经做好系统的TF卡
各种改动后的EMMC系统

核心操作步骤：

从EMMC启动系统，登陆桌面并打开终端命令行更改卷标

sudo su
fatlabel /dev/mmcblk0p1 emmc-boot
e2label /dev/mmcblk0p2 emmc-rootfs

vim /boot/firmware/cmdline.txt
将writable替换为emmc-rootfs  然后保存退出

vim /etc/fstab
将writable替换为emmc-rootfs  然后保存退出

sync;

插入TF卡，重启系统
默认优先从TF卡引导系统，进入系统之后，可以挂载EMMC分区进行备份压缩

RK3588 的VOP (video output process)分为4个Port

port	分辨率
VP0	4K
VP1	4K
VP2	4K
VP3	1080P

支持8个图层,每个图层可以灵活分配到每个Video Port上。

RK3588 支持的显示接口

2个DP
2个HDMI/eDP 共用接口
2个MIPI DSI
