cp defconfig arch/arm64/configs/rk3588s_cp4b_defconfig

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

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：

1. 假如您手边有一张已经做好系统的TF卡
2. 各种改动后的EMMC系统

核心操作步骤：

1. 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;

2. 插入TF卡，重启系统

3. 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

@ccjjww1222
新的SDK已经支持单任务多核处理，最新的SDK 支持的多核情况如下图

@ccjjww1222 谢谢提供的宝贵意见！我们一起努力！

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
• BT656/BT1120

如下链接文章写的比较好，值得研究。

摘一部分：

简单的理解
drm里有crtc，plane，connector这三个东西，可以理解

connector就是屏幕，比如一个hdmi一个connector num， 一个dsi一个connector num
crtc表示vop， 一个屏幕一般对应一个crtc
plane就是图层，比如视频层在plane2，UI在plane1， 视频在UI上面

@harry-huang 上面的操作是基于ubuntu22系统。其他系统可以参考

宝塔是什么，可以查看demo页面

针对Cool Pi 4B主板，如需更新u-boot操作如下：

0823版本请升级到0904

1. 下载0904版本bin文件
   uboot.zip

2. 解压zip，将bin文件拷贝到U盘或Tf卡根目录

3. 将U盘或Tf卡插入主板，连接Debug串口到PC电脑，打开串口终端工具，主板通电，连续输入大写CP中止u-boot自动启动

   备注：请注意U盘启动或升级仅支持插入USB3 下层端口

4. 在u-boot shell命令行窗口，
