    • 早期版本 Ubuntu22.04 rknn toolkit lite2环境部署

      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

    • Ubuntu docker user guide

      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
      
      Share images, automate workflows, and more with a free Docker ID:
       https://hub.docker.com/

    • Coolpi 4b EMMC镜像备份导出方法

      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;
      
      1. 插入TF卡,重启系统

      2. 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

      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

    • Coolpi 4b bootloader命令行升级方法

      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,
        针对串口输出信息如下的主板

      A) 如果是从U盘导入文件升级步骤
      usb reset
      load usb 0:1 0x800000 uboot.img
      mtd erase nor0 0x200000 0x500000
      mtd write nor0 0x800000 0x200000 0x500000
      擦除与写入过程请勿断电或重启
      
      B) 如果是从TF卡导入文件升级步骤
      mmc dev 1
      load mmc 1:1 0x800000 uboot.img
      mtd erase nor0 0x200000 0x500000
      mtd write nor0 0x800000 0x200000 0x500000
      擦除与写入过程请勿断电或重启
      
      1. 等待执行完毕,确认无异常后,断电或reset即可。

      2. 升级完成后,串口输出信息如下
