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.

@winger
找个U盘，先把镜像制作到U盘，插入电脑启动以后，使用如下命令格式化EMMC

sudo mkfs.ext4 /dev/mmcblk0

@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

@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。

@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

@Momo-0
The 3.5mm headphone jack has output and MIC functions.

@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.

@mez62 可以插上试试

@george Is there a possibility for /boot/ on the FLASH and then the root partition being on the nvme drive with the uboot?

@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?

@28717885
发规格书看看，具体是什么东西？

貌似是arch带的编译器版本太高了
用老编译器编的内核可以正常使用panthor

@mainbord
At present, the mainline kernel EDP interface is not supported. The CM5-LAPTOP configuration has been submitted for mainline review and should be released soon.

just use flatpak

there are many app on flathub with arch64 support.
