脚本具体镜像大小要修改一下，28G的数据DD的镜像尺寸至少要30G.默认脚本的8G镜像大小不合适。

@Twsuts-0
你不能工作的启动信息有没有，发一下。

@Twsuts-0
参考如下附件backupimg.sh

@rtmtree
As shown in the figure below, this control chip only supports the SATA3.0 protocol.

@rtmtree
Confirm the specific model of this chip and send it out for me to check the specification sheet.

@Momo-0
Confirm that the USB camera device has not been recognized, and verify if other images are functioning properly or if all images are no longer recognized properly. If so, there may be hardware abnormalities.
When the machine is powered off, unplug the LCD cable again. The USB signal of the camera is connected to the LCD cable.

@rtmtree

1. Confirm that SSD supports NVME protocol, SATA machines cannot support it
2. ls /dev confirm if any nvme devices have been found
3. Use commands to format the hard drive

sudo mkfs.ext4 /dev/nvme0*

@Momo-0
Please confirm which image you are using, and you can also use the following command to view the USB device:

lsusb

@rtmtree
The 8MB is SPI-NOR memory, which stores bootloader and UBOOT internally. If the disk is formatted, it will not start properly. Don't worry, just update the image again. Provide an update method later.

Refer to the following document：

Add the configuration as shown in the following figure, and then compile and update the kernel.

Please provide detailed error message.

@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

@traceback
从log信息看固件的分区有问题导致，先把SD卡格式化一下，然后重新制作启动盘。

@plumlis
Thank you very much for your recommendation, there are many very good applications.

暂时没有做其他版本的适配。

If the firmware of Ubuntu is created on a USB drive and then inserted into a computer, can it boot up？

@Momo-0
Can the machine enter UMS mode? If it can enter UMS mode, you can first try formatting the UMS disk, and then use Ethcer to load the latest image and flash the machine.Refer to the following document.

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。
