@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。

• Two HDMI2.1 interfaces with a maximum resolution of 8K.

• Stereo headphone stand with MIC input function.

• Two native USB2.0 interfaces.

• One TYPEC power supply interface, consistent with CP4.

• The external power interface of 2PIN can support DC power input.

• 1 standard PCIE 4X connector, currently only supports PCIE3.0 2X/1X mode.

• SSD interface, only PCIE-M2-2242 size hard disk is supported.

• Standard 7PIN SATA3.0 interface, 4PIN power interface.

• M.2 WIFI module interface, supporting multiple general WIFI modules.

• Dual MIPI LCD interfaces support simultaneous output of two MIPI interface LCDs. The resolution of a single LCD is up to 1920 * 1200. It supports the MIPI DSC function.

• Four independent MIPI camera interfaces support four camera inputs at the same time. It can be configured as 2X4LINE or 4X2LINE mode.

Bot-level interface

• One 30PIN EDP interface can directly drive LCD output.

• MXM 314PIN core board connector.

Welcome to put forward good suggestions. We can consider revising them.

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
  ![5594e1d4-3a7b-46fc-a7b5-2a9fe418dfc0-image.png]
  

• 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
  

@emtohere
使用TF卡的话不需要进入UMS模式，直接用读卡器通过etcher软件写就好了。不要用RKD工具。

@emtohere
机器默认刷机是使用etcher来刷。不是用RK官方工具，上电多次按开机按键，机器就会进入UMS模式，然后使用etcher软件加载固件，选择设备刷机即可。

@emtohere 你是使用的EMMC还是TF卡？能否提供开机日志信息。

@zehui
The image package we released has already installed the GPU driver by default. Regarding the issue of video playback lag, it has nothing to do with the GPU driver, mainly the VPU. Our image has integrated ffmpeg hardware decoding driver, which can support local video hardware decoding. If it is a network video, due to the system's default browser using snap mode, the hardware decoder cannot be called and can only be decoded through CPU software, resulting in lower smoothness and power consumption.

@emtohere
4b的机器按照这个文档操作即可。

Using the kernel at the following address, after compilation, headers. tar. gz will be generated, and then decompressed to the/usr directory.

@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

@reukiodo
Hardware versions after V20 can support TYPEC PD charging, but it can only be used when turned on, and only supports adapter charging when turned off.

@berkaroad
Thank you very much
