@Momo-0 I won't be making a guide anytime soon, but you'd have to flash the image to emmc or SPI: https://danielc.dev/rk/devices/genbook/

It's not very useful yet. ACPI is the only way I've been able to get a generic UEFI image booting. And last time I tried the trackpad didn't work but the keyboard did (any idea why @george ?), along with a bunch of other hardware (USB-A port)

Device tree won't even boot at all, and I couldn't get any UART output to figure out what went wrong. But it probably wouldn't work in the first place because the genbook needs a patched kernel.

@Momo-0 any help is appreciated

After letting the Laptop rest for a few days, the cam was back shortly, went away after a few seconds though.

@berkaroad said in 分享被动散热改造:

改造后
环境温度： 20度 （室内温度计）
开机温度 ：31.5度
开机10分钟后温度：35.2度
测试chrome 浏览器播放腾讯视频1080p 1小时后温度：43.5度

Launch this test for 20 minutes please

@berkaroad That's sad.
Actually, Kernel 5.10 on the Armbian is quite okay.
But I dont know why when I tried Xonotic, it's very laggy.
I tried to install GPU support by following solution in the webboard.
But still got like 10 FPS.
So, I think updating the kernel could help.

@george 内核启动设置了ipv6.disable=1，今天发现wifi突然断开后无法重连，禁用wifi后再启用也无法恢复，重启电脑后正常。（新问题）

查看日志如下： journalctl -xeu wpa_supplicant

@george Thanks a lot, I will contact the Aliexpress seller

@george It's coming back again.
Thank you so much.

@george that did it, wireguard works now, thanks

@george Thanks for your reply. Local videos from EMMC play well. I am talking about network videos in browser like youtube. Present driver and software ubuntu 24.04 (older kernel) uses almost 50% of CPU just to play a 1080p video. I have an Orange Pi 5b, that has same processor and GPU running orange pi droid (a version of android). That plays youtube videos with much less resources and runs much faster. I am looking for an android version to run on coolpi notebook. Where can I find that? (i have already tried armabian. but did not like that on coolpi laptop. Android for COM5 does not work)

@enok71
I don't have a direct understanding of what happened to this computer, why does it seem to have so many impurities inside.
If you need any information, please send an email to george@cool-pi.com

@george 谢谢 我先试试

flatpak 更换国内仓库（上海交大）：

flatpak remote-modify flathub --url=https://mirror.sjtu.edu.cn/flathub

@berkaroad 好的，有机会我把背板拆下来看看呢

Flatpak is a good thing for Arm64 ,but may have some problem on CM5

As we know ubuntu on cm5 is using panfork for GPU by patched mesa.
but flatpak has their own mesa without panfork patched.

So some app (like video player or game) install from flatpak can not running with GPU. and Maybe toooo slow.

But for wechat its fine.

@jugg
暂时没有做其他版本的适配。

@George The latest Ubuntu image won't boot from either a usb stick nor if its imaged onto the laptop from my Macbook using ums mode,
both Debian and Arabian boot fine.

@Eel
There is currently no separate purchase link for the casing of this machine. If any part of your machine is damaged, you can send it out and I can coordinate with the factory to see if it can be shipped separately.

@George 好的晚上试下。
extlinux.conf 文件中， append 那一行 追加 “cmdline”

在x86机器上的docker环境 ubuntu:20.04 下可以构建成功。arm 笔记本上发现最后一步不形，估计是使用的工具有x86下的二进制文件.

apt install build-essential device-tree-compiler bc python2 ./build-loader.sh cm5-notebook

@prcups 我现在也改用 6.1内核，目前用下来均正常。按需再定制内核。

我会用docker构建跨平台的镜像，默认内核未开启 CONFIG_BINFMT_MISC，在使用中慢慢弄，也是很好学习的过程。 😊

@George ok. just suggest for default. I compile and well done.

@wzy
已经在处理CM5-EVB和CP4的支持。
