@night 机器TYPEC前端电源芯片耐压可以达到28V，极限可以到34V，所以你的适配器规格没有任何问题。
开发板的电源部分一直是我们设计最优先考虑的方向，所以前端第一级电源花了很多功夫，考虑到用户各种各样适配器的规格，最终选择目前国内少数几家真正能做车规级别电源方案的厂家。尽量保证前端电源稳定可靠。

If you need to boot armbian normally, you need to update the loader file to version 0104.

Follow the steps below to update the loader:

• Download the latest loader file One Drive

• Short the 2 pins shown by the arrow.
  

• The USB interface and computer connection.
  

• Plug in the power supply and open the upgrade software. The machine enters the maskrom upgrade mode.
  

• choose to write by address
  

• Click Execute to complete the loader update.
  

• If the computer prompts that the USB driver cannot be found, please download and install the driver software first.One Drive
  

CPU

测试方法：

sudo apt install sysbench

RK3588S单核心每秒事件数2598，8核每秒事件数13846；同步对比 i7-7700 ，单核每秒事件数1438，8核每秒事件数8469。可见ARM在CPU方面并不比X86弱。

GPU

测试方法：

sudo apt-get install glmark2* -y

X11 gl

X11 gles 3.1

WAYLAND gl

WAYLAND gles 3.1

@zensation The radiator can be matched with raspberry pi. A separate fan is OK. Normally, it is not necessary to add aluminum alloy fins on the CPU.

Recently, I have been working hard to push CM5 NOTEBOOK to the ARMBIAN mainline. Further information will be released as soon as possible. Thank you for your support.

Coolpi supports UMS to update emmc firmware, as follows:

1. Update the latest versions of loader and uboot images. You can also synchronize uboot code and compile it yourself.

git clone https://github.com/yanyitech/coolpi-loader
cd coolpi-loader
./build-uboot.sh cp4b

2. Connect a dual A port USB cable to the computer and the upper USB 3.0 interface. Plug in the power and press the power button three times, and the machine will enter UMS mode.
   
3. Use Etcher software to update the software.
   

内核已经更新，同步develop代码到最新，编译替换内核，KO文件解压到/lib/modules目录，重启机器会看到两个WIFI节点。

使用其中一个连接外网

另外一个可以作为热点

@jugg 升级uboot需要进入loader模式或者maskrom模式，不是UMS

@veryy 把内核更新到最新版本。提供一下dmesg信息。

@mtiqbal 123

@qys2022 没有反。

@jugg 这个应该是系统自带的，网上找一下如何关闭。

Refer to the following documents：

@maxpol I2C3 I2C5 cannot be changed to other pinsOf course, you can try opening other I2C channels.

@etrin

1. troubleshoot the power issue and try playing a network video to observe if there is a restart phenomenon.

2. If you have a debug serial port board on hand, you can try monitoring the log information. And submit it to the community for our analysis.

@qys2022 不使用PCIE3.0可以不用。
