Cool Pi Cm5-Laptop Linux Quick Start Guide

@yfblock
The partition format of Armbian is different from Ubuntu, so it is recommended to format EMMC before upgrading the image when switching between the two systems. -
@george i can't enter any system. Even through USB drive.
-
@yfblock
Test several USB drives and find a USB 2.0 interface drive. There may be compatibility issues with USB3.0. -
@george Thank you, I have solved this problem using usb2.0 drive. I have another question. What should I do to install the system on NVME? (This message was sent by coolpi notebook).
-
@yfblock
At present, the Uboot section has not added support for NVME, so it cannot be supported at the moment. We will provide support steps after the Uboot driver update. Thank you for your support. -
I replaced the board in my laptop with the newer one and compiled the firmware, but now i have two wlan adapters showing and no bluetooth available.

Run the following command and send the result.lsusb -

@Momo-0
From the log information, it appears that the USB Bluetooth network card was not recognized. It is recommended to remove the core board, remove the WIFI module, clean the gold finger with an eraser, and then install and retest. -
@george i cleaned the contacts on the wlan card and the main processor card, still the usb bluetooth card doesnt show up maybe the board is faulty?
-
@Momo-0
I'm really sorry, this board was tested before it was shipped, and it could also be caused by an abnormality during transportation. I will arrange to send you a new one. Because it is currently the May Day holiday, it may need to be processed after the holiday. I deeply apologize for the trouble I have caused you. -
@george i also have ubuntu showing two realtek wlan devices, maybe thats a clue to something?
Also i compiled for V20 since i replaced the motherboard -
@Momo-0
Two WLAN nodes are normal, and the default configuration for drivers is to generate two nodes, even one node can be used. -
I want to try the Kylin system in Baidu Pan, but unfortunately, I can't start it. Now the problem is that I can't enter MUS mode by quickly pressing the power button 8 times. No matter how I start or try, it keeps showing the logo and then rebooting repeatedly. Is there any other way for me to reflash the system?

From the phenomenon you described, it appears that the onboard EMMC partition table has been damaged. Try formatting the onboard EMMC memory according to the following operation method. After successful completion, you can enter UMS mode normally.- Find a USB drive and use an etcher to create an image of Ubuntu on it. Remember to back up important data from the USB drive before creating it.
- Insert the USB drive into the USB port of the laptop and start the machine. If everything goes smoothly, the machine will successfully boot from the USB drive.
- Use commands to format onboard EMMC memory
sudo mkfs.ext4 /dev/mmcblk0- Remove the USB flash drive and press and hold the power button for 10 seconds to forcibly shut down the machine.
- Connect the TypeC port to the X86 computer and press the power button multiple times to enter UMS mode.
-
@guyii
Firstly, create a system image to a USB drive or a portable hard drive using the etcher. Then, insert the computer and start it up. The machine will first start from the USB drive. After entering the system, format the EMMC using the following command to enter UMS mode again.sudo mkfs.ext4 /dev/mmcblk0 -

I received the V20 mainboard and installed it. I followed these instructions including pulling, compiling and installing the latest kernel source, and the system boots fine, however it does not recognize the NVMe card.
-
@george would you mind taking a look at this issue. I have not been able to find the instructions specific to the V20 board upgrade, so I may have missed something. I've pulled the notebook apart again and reseated the NVMe stick. I installed Ubuntu 24.04, but maybe I should have used 22.04?
-
@george Never mind. It just started working. No clue why, but I'll monitor it and let you know if it starts to get flaky.

@george 一开始 进入 UMS模式，用另一台电脑用 balenaEtcher 刷最新的Ubuntu镜像，中途另一台电脑故障死机，刷机失败。
之后coolpi笔记本无法进入UMS模式，用64GB USB2.0的sandisk U盘刷了最新的Ubuntu镜像后，插上coolpi笔记本后开机，能看到Ubuntu启动logo，之后就是一直黑屏状态，也无法用 Ctrl + Alt + F1（到F12） 切换到控制台模式。U盘刷Ubuntu的内核5.10版本的那个，也是最终黑屏状态。这个如何恢复？
制作启动U盘的，是用linux 的 dd命令写入img镜像文件的
