目前ARM平台的升级工具只有rkdeveloptool，github的这个工具是很老的版本，还不支持多存储设备的升级。

• 如果是ARM64的ubuntu系统，coolpi4b机器进入UMS模式，然后双击img镜像文件，选择对应的UMS设备就可以升级。
• github有etcher的源码，也可以编译生成ARM64的版本用于系统升级。
• 也可以把ubuntu系统做到u盘，然后使用u盘启动，然后双击img镜像也可以刷到EMMC，或者TF卡。

目前还是beta版本，等后续的release版本再考虑移植。如果有兴趣可以自己尝试移植，里边最主要的步骤是X86上面的模型转换过程。需要更详细资料可以邮件索取：george@cool-pi.com

Description

RKLLM software stack can help users to quickly deploy AI models to Rockchip chips. The overall framework is as follows:

In order to use RKNPU, users need to first run the RKLLM-Toolkit tool on the computer, convert the trained model into an RKLLM format model, and then inference on the development board using the RKLLM C API.

• RKLLM-Toolkit is a software development kit for users to perform model conversionand quantization on PC.

• RKLLM Runtime provides C/C++ programming interfaces for Rockchip NPU platform to help users deploy RKLLM models and accelerate the implementation of LLM applications.

• RKNPU kernel driver is responsible for interacting with NPU hardware. It has been open source and can be found in the Rockchip kernel code.

Support Platform

• RK3588 Series
• RK3576 Series

Download

• You can also download all packages, docker image, examples, docs and platform-tools from RKLLM_SDK, fetch code: rkllm

RKNN Toolkit2

If you want to deploy additional AI model, we have introduced a new SDK called RKNN-Toolkit2. For details, please refer to:

https://github.com/airockchip/rknn-toolkit2

Notes

Due to recent updates to the Phi2 model, the current version of the RKLLM SDK does not yet support these changes.
Please ensure to download a version of the Phi2 model that is supported.

把这个有问题的源删除掉，换成coolpi的ppa源。

@Yannis
你用的哪款机器，固件版本更新到最新试试。

@阿里 said in 电源底板上电最大可以上多大需要多少安培:

有什么方法增大电源的功率吗

你换个功率更大的适配器就可以了，比如12V3A的。

@阿里
不会的！DCDC输入的电压可以到30V以上。超过12V的电源输入建议使用2PIN 2.54mm连接器，如下图所示：正常工作12V 1.5A就可以满足系统要求，如果有加其它外设比如移动硬盘 SSD之类的，根据实际情况增加电源功率。

@yfblock
At present, the Uboot section has not added support for NVME, so it cannot be supported at the moment. We will provide support steps after the Uboot driver update. Thank you for your support.

@yfblock
Test several USB drives and find a USB 2.0 interface drive. There may be compatibility issues with USB3.0.

@yfblock
The partition format of Armbian is different from Ubuntu, so it is recommended to format EMMC before upgrading the image when switching between the two systems.

@yfblock
Is your machine currently unable to enter UMS mode? It is possible that the file system of EMMC is damaged. You can find a USB drive and create an image of Ubuntu to it. Then, start the system from the USB drive and format EMMC in the system. Use the following command:

sudo mkfs.ext4 /dev/mmcblk0

Machine Introduction

COOLPI CM5 open-source notebook is a product that combines high performance, portability, and open-source spirit. It not only meets the basic computing needs of users, but also provides an ideal platform for those who enjoy free exploration and technological creation.

Installing the system

The machine is installed with Ubuntu 22.04 system by default at the factory. If users need other versions, they can update them according to the following tutorial.
The default username for the machine is: coolpi Password: 123

Download image

As shown in the following figure: System images can be downloaded through 百度网盘 or Onedrive.

Select the image that needs to be updated, and the image type will continue to be updated.

Download tools

Coolpi defaults to using Etcher to update system images, which can be obtained through Baidu Cloud, Onedrive, or the official website.

Machine enters UMS mode

The Type-C port of the machine is connected to the computer. When the Coolpi laptop is turned off, it can quickly press the power button multiple times, usually no less than 8 times, and the machine will enter MUS mode. The computer will recognize an icon for a USB drive. As shown in the following figure:

The X86 computer will recognize a UMS device.

Load image and flash

Follow the three steps shown in the figure to burn the image file. After the burning is completed, a forced restart is required. The method of forced power down is to continue holding down the power button for 10 seconds.

After downloading, restart the machine as shown in the following figure.

Update kernel

The kernel of Coolpi will continue to be updated, and users can also compile the mainline kernel themselves to upgrade the machine, following the steps below. The compilation of the kernel part in the following figure is completed on the Coolpi laptop, and users can also cross compile on the X86 computer. The method and steps are the same.

Synchronize kernel

sudo apt-get update
sudo apt-get upgrade
sudo apt-get install git 
git clone https://github.com/yanyitech/coolpi-kernel.git

Compile kernel

First, install the git toolkit, and it is best to update the system to the latest version before installation. Install some kernel dependent packages, then run the compilation script, enter numbers to select the corresponding machine model, and the compilation can proceed normally.

sudo apt-get install flex bison libssl-dev
sudo ln -s /usr/bin/python3.10 /usr/bin/python
cd coolpi-kernel 
./build-kernel.sh

8. cm5-8uart
9. cpnano
10. exit

Enter option number: 7

Upgrade machine kernel

After the normal compilation of the kernel, an out folder will be generated with the directory, which contains all the files required by the kernel. You can update the newly compiled kernel to the machine by using the following command.

Use the following command to update the kernel.

sudo cp ./out/* /boot/firmware -R
sudo rm /lib/modules/* -R
sudo tar -zxvf ./out/modules.tar.gz -C /lib/
sync
sudo reboot

If the kernel was cross compiled using X86 machines, the kernel can be updated using the following methods:

• Use the Samba shared folder to copy the compiled files to the Coolpi machine.
• Use mobile storage devices such as USB drives to copy.
• The coolpi machine enters UMS mode, connects to the X86 computer, enters the USM mobile disk, deletes all files, and copies all files in the generated out directory to the UMS mobile disk. Then force a restart of the Coolpi laptop.

Change the startup logo

Users can update the startup logo of the machine by copying files, using the following command.

sudo cp ./logo.bmp /boot/firmware
sync
sudo reboot

Below is a standard format for a logo file that users can download and modify. Please note that the pixel size, name, and format of the file should not be changed.
logo.zip

Frequently asked questions

The machine cannot enter UMS mode

Due to incomplete image updates, the partition table of EMMC is damaged, and the machine cannot enter UMS burning mode. The following methods can be used to repair the EMMC partition table.

• A USB interface mobile storage device with a capacity of no less than 16GB, and an X86 computer can burn any image to the USB device through ETCHER software.

• Insert USB storage device into the USB interface of the Coolpi laptop
  
• The machine will first start from the USB storage device when turned on. Then enter the system. Format EMMC using the following command.

sudo mkfs.ext4 /dev/mmcblk0

@kaicn13 理论上是可以的，前提是需要结构资料和连接器PIN定义。

@清客
有没有串口工具，提供一下启动日志。或者找个U盘，镜像做到U盘里边测试。TF卡制作之前最好格式化一下。

@Momo-0
The structure is the same and can be directly replaced, then upgrade to the latest V20 software.
