Cool Pi Cm5-Laptop Linux Quick Start Guide

I followed the kernel update instructions (git clone, compile, copy, reboot) and now I have no network interfaces and no bluetooth. I don't have time to dig into it right now, just wanted to warn that something may be missing in the instruction.

@george Thanks that solved my problem.

I lost the PD charging after flashing to the Ubuntu system. Then I flash the Armbian system, but it couldn't boot up or enter the UMS mode.

@yfblock
Is your machine currently unable to enter UMS mode? It is possible that the file system of EMMC is damaged. You can find a USB drive and create an image of Ubuntu to it. Then, start the system from the USB drive and format EMMC in the system. Use the following command:

sudo mkfs.ext4 /dev/mmcblk0

I Download the image form onedrive(path: CoolPi CM5 NOTEBOOK/ubuntu/20231027...), but it couldn't start.

george

@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.

george

@yfblock
Test several USB drives and find a USB 2.0 interface drive. There may be compatibility issues with USB3.0.

yfblock

@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).

george

@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.

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?

george

@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

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?
