    • Cool Pi Cm5-Laptop Linux Quick Start Guide

      mian.png

      Machine Introduction

      COOLPI CM5 open-source notebook is a product that combines high performance, portability, and open-source spirit. It not only meets the basic computing needs of users, but also provides an ideal platform for those who enjoy free exploration and technological creation.
      接口.png

      Installing the system

      The machine is installed with Ubuntu 22.04 system by default at the factory. If users need other versions, they can update them according to the following tutorial.
      The default username for the machine is: coolpi Password: 123

      Download image

      As shown in the following figure: System images can be downloaded through 百度网盘 or Onedrive.

      download.png

      Select the image that needs to be updated, and the image type will continue to be updated.

      image.png

      Download tools

      Coolpi defaults to using Etcher to update system images, which can be obtained through Baidu Cloud, Onedrive, or the official website.
      etcher.png

      Machine enters UMS mode

      The Type-C port of the machine is connected to the computer. When the Coolpi laptop is turned off, it can quickly press the power button multiple times, usually no less than 8 times, and the machine will enter MUS mode. The computer will recognize an icon for a USB drive. As shown in the following figure:
      键盘3.png
      The X86 computer will recognize a UMS device.
      ums.png

      Load image and flash

      Follow the three steps shown in the figure to burn the image file. After the burning is completed, a forced restart is required. The method of forced power down is to continue holding down the power button for 10 seconds.
      download2.png
      After downloading, restart the machine as shown in the following figure.
      键盘4.jpg

      Update kernel

      The kernel of Coolpi will continue to be updated, and users can also compile the mainline kernel themselves to upgrade the machine, following the steps below. The compilation of the kernel part in the following figure is completed on the Coolpi laptop, and users can also cross compile on the X86 computer. The method and steps are the same.

      Synchronize kernel

      sudo apt-get update
      sudo apt-get upgrade
      sudo apt-get install git 
      git clone https://github.com/yanyitech/coolpi-kernel.git
      

      Compile kernel

      First, install the git toolkit, and it is best to update the system to the latest version before installation. Install some kernel dependent packages, then run the compilation script, enter numbers to select the corresponding machine model, and the compilation can proceed normally.

      sudo apt-get install flex bison libssl-dev
      sudo ln -s /usr/bin/python3.10 /usr/bin/python
      cd coolpi-kernel 
      ./build-kernel.sh
      Welcome to using Coolpi Development Board!

      Please enter a number to select your machine

      9. cpnano
      10. exit
      
      Enter option number: 7
      

      Upgrade machine kernel

      After the normal compilation of the kernel, an out folder will be generated with the directory, which contains all the files required by the kernel. You can update the newly compiled kernel to the machine by using the following command.
      build1.png
      Use the following command to update the kernel.

      sudo cp ./out/* /boot/firmware -R
      sudo rm /lib/modules/* -R
      sudo tar -zxvf ./out/modules.tar.gz -C /lib/
      sync
      sudo reboot
      

      If the kernel was cross compiled using X86 machines, the kernel can be updated using the following methods:

      • Use the Samba shared folder to copy the compiled files to the Coolpi machine.
      • Use mobile storage devices such as USB drives to copy.
      • The coolpi machine enters UMS mode, connects to the X86 computer, enters the USM mobile disk, deletes all files, and copies all files in the generated out directory to the UMS mobile disk. Then force a restart of the Coolpi laptop.

      Change the startup logo

      Users can update the startup logo of the machine by copying files, using the following command.

      sudo cp ./logo.bmp /boot/firmware
      sync
      sudo reboot
      

      Below is a standard format for a logo file that users can download and modify. Please note that the pixel size, name, and format of the file should not be changed.
      logo.zip

      Frequently asked questions

      The machine cannot enter UMS mode

      Due to incomplete image updates, the partition table of EMMC is damaged, and the machine cannot enter UMS burning mode. The following methods can be used to repair the EMMC partition table.

      • A USB interface mobile storage device with a capacity of no less than 16GB, and an X86 computer can burn any image to the USB device through ETCHER software.

      2e526794-d324-4f9b-9056-c401d70cc231-image.png

      • Insert USB storage device into the USB interface of the Coolpi laptop
        2db87eee-899d-411b-a168-6477c236e138-image.png
      • The machine will first start from the USB storage device when turned on. Then enter the system. Format EMMC using the following command.
      sudo mkfs.ext4 /dev/mmcblk0

      @Momo-0 said in Cool Pi ARM Notebook Preview:

      is there a Possibility to buy the bare v2 board if we already have the Laptop?

      V2 bare boards can be purchased separately. You can communicate with customer service through the following link.
      https://www.aliexpress.com/item/1005006690709030.html?gatewayAdapt=4itemAdapt
      The bottom plate of V2 has been modified in four main ways:

      1. As shown in the figure below, replace the WIFI module with a PCIE-M2 connector, which defaults to the RTL8852BE module and can be replaced by the user. Standard PCIE+USB interface.
        dc36c980-54b9-482a-9c31-138fd6c34e46-image.png
      2. The USB3.0 interface adds a redriver circuit to improve the compatibility of USB3.0.
      3. Modify and add TYPEC PD charging support. Currently, it only supports PD charging when turned on, and does not currently support charging when turned off.
      4. The LCD connector adds touch signals, allowing the machine to expand the touch screen.

      Currently, V2.0 machines can support TYPCE PD charging. You need to use an adapter that supports the PD protocol.

    • RE: Power diagram and sequence

      @alfek
      Sorry, CM5-EVB is currently unable to directly test the VCC5V0_USB current. If you have some hands-on ability, you can try adding a 100 milliohm sampling resistor at the position shown in the diagram to determine the current by testing the voltage at both ends of the resistor.

      You can try booting with a USB drive, formatting the EMMC, and burning the image again.

    • RE: cool pi 4b & CM5 linux system support compile u-boot

      @jugg 默认boot_merger这个二进制是x86架构的,需要更换为aarch64架构。你可以先再X86上面编译。或者使用下面的文件:
      uboot.rar

      @jugg
      配置完以后要保存然后复制到对应的defconfig文件上。

      make ARCH=arm64 menuconfig
      make ARCH=arm64 savedefconfig
      cp defconfig  ./arch/arm64/configs/rk3588_cpcm5_evb_defconfig
      ./build-kernel.sh cm5-evb-v11

      Please note that the updated USB port is the USB 3.0 interface located on the upper layer near the power connector.

      @etrin
      Can the machine enter UMS mode normally? If it can enter UMS mode, you can try formatting the UMS disk using Windows tools and then burning the Ubuntu system again. Generally, if the system can be burned normally, it indicates that there is no hardware problem.
