@traceback 兄弟，问题解决了吗？我遇到了一样的问题，还不知怎么处理。

@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.

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.

@jugg
你是要用U盘刷机吗？最近的镜像是IMG文件，只能使用USB接口连接电脑，通过etcher刷机。

@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
