flatpak 更换国内仓库（上海交大）：

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

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.

@wzy
已经在处理CM5-EVB和CP4的支持。

@george
Many thanks for your reply. Is there any guide about how to compile mpp/rknpu module with cool pi kernel?

And is it possible to compile cool pi kernel 6.1 with panfork?

@yfblock intel ax201
但前提是你需要编译内核，启用intel的驱动模块，并且把官方intel的固件拷贝进去就行了。

coolpi默认屏蔽了intel

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

@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.

How to update to 6.x kernel?
I tried to compile this
https://github.com/yanyitech/coolpi-kernel/tree/linux-6.1-stan-rkr1
Next I install kernel according to the instructions
https://forum.cool-pi.com/topic/514/cool-pi-cm5-laptop-linux-quick-start-guide

5.10 installed successfully but after install 6.1 it's does not booted

BuildRoot 也要跟上呀

@anernest
This product is designed for enthusiasts and is very suitable for DIY users to develop, assemble, and build their own. Currently, after dismantling the machine, they do not enjoy after-sales policies. However, various accessories of the machine, including motherboards, core board and shell materials, can be sold separately for secondary sales. And we have a dedicated team to assist users in solving various problems in use and design. Notebook products are an extension of the CM5 core board, and currently there is no separate theme in the community. If you have any questions, you can directly post them under the CM5 theme. Thank you for your support.

The latest laptop motherboard design has changed the WiFi section to a standard M2 interface, making it easy for users to replace according to different needs. Early machines can also be upgraded by replacing the motherboard.

@jugg 这个只需要替换内核就可以了。跟之前其它FS的方法是一样的。

also support RTL8188EUS module
