按照如下文档操作，机器先进入UMS模式，然后用etcher烧录脚本生成的镜像即可完成升级。

@jugg
这个5G模组还在设计中。

@jugg
这个是RTL的驱动注册有问题，你可以加LOG信息在rtk的驱动里边跟踪一下，定位到具体哪里报异常。然后再想办法解决。

@jugg
这个要看具体的log信息，是驱动有冲突还是什么问题，你可以使用PCIE的网卡暂时规避这种问题，CM5的机器可以支持多种型号的PCIE+USB网卡。
这个模组目前是针对CM5的笔记本设计的，CM5-EVB暂时用不了。

Module selection

• RM500Q-GL is a 5G NR/LTE-A/UMTS/HSPA+ wireless communication module with receive diversity. It
  provides data connectivity on 5G NR SA and NSA, LTE-FDD, LTE-TDD, DC-HSDPA, HSPA+, HSDPA,
  HSUPA and WCDMA networks with standard PCI Express M.2 interface.

  It supports embedded operating systems such as Windows, Linux and Android, and also provides GNSS
  and voice functionality to meet specific application demands.

• The following table shows the frequency bands and GNSS type of RM500Q-GL module.

Schematic design

Module Pin Definition

• Module pin layout,It can support PCIE interface or USB3.0 interface. We chose USB3.0 interface design, which is relatively easy to handle for compatibility and driver.

Signal connection

• Schematic encapsulation definition, based on the PIN definition of the module.When connecting USB3.0 or PCIE signals, they should be crossed, with TX connected to processor RX and RX connected to processor TX.

• Select the minimum GPIO method because the Coolpi CM5 laptop completely loses power during sleep, so it does not support module wake-up system. The GPIO connection is as follows:
  

• The following table describes the signal list, which is mainly divided into power supply, USB3.0, SIM card, and control signal.

Power supply

The following figure shows a reference design for +5 V input power source based on an DC-DC
TMI3253SH. The typical output of the power supply is about 3.7 V and the maximum load current is 3A.

Power sequence

The turn-on scenario is illustrated in the following figure.

• tpower-on is time the interval between VCC and RESET_N HIGH level, which is a typically 33 ms. It is
  measured when RESET_N is not pulled down by the host device.
• tturn-on is the time interval between FULL_CARD_POWER_OFF# HIGH level and RFFE_VIO_1V8(an internal LDO output) HIGH level, which is typically 68 ms.
• tbooting is the time interval between RFFE_VIO_1V8 HIGH level and the USIM_VDD power-on.
  

Turn on the Module

It is recommended to use a host GPIO to control FULL_CARD_POWER_OFF#. A simple reference circuit
is illustrated in the following figure.

Turn off the Module

Pulling down the FULL_CARD_POWER_OFF# pin will turn off the module. The turn off
scenario is illustrated in the following figure.

@jugg
如果是TI的库仑计，而且内核有驱动，正常DTS配置一下就可以了。如果是linux内核没有的库仑计型号，就需要自己加驱动，相对麻烦一点。

@jugg
笔记本用的是CW2015的库仑计。这颗会比较麻烦，使用前必须要测试充放电曲线，而且只能厂家帮忙测试。

@jugg
你电池是自带库仑计的吗，如果是这样需要知道库仑计的型号，然后DTS增加驱动即可。单纯升级notebook的系统大概率用不了。一般笔记本电池内置的库仑计TI的型号会比较多。

@ytfycy
是从现有的CM5备份，操作完以后会生成一个img文件，再用etcher升级到其它CM5机器即可。

@ytfycy
保存下面代码为sh脚本，然后放到U盘或者移动硬盘里边执行，执行前先增加一下权限。然后以root权限运行脚本。

!# /bin/sh

IMAGE_NAME="$(date "+%Y%m%d")-rootfs.img"
IMAGE_SIZE=8192
LOOP_NUMBER=$(losetup -f)

echo "01:remove firstrun"
rm /var/lib/misc/firstrun
echo "02:Establishing a mount directory"
mkdir ./mnt
echo "03:dd image file"
dd if=/dev/zero of=./$IMAGE_NAME bs=1M count=$IMAGE_SIZE
echo "04:Mirror Partition"
printf 'n\np\n1\n32768\n1081343\nn\np\n2\n1081344\n16777215\nw\n' | fdisk ./$IMAGE_NAME

losetup -d $LOOP_NUMBER
echo "09:backimg ok"
fdisk -l ./$IMAGE_NAME

@davidm

1. It is recommended to use a USB 2.0 interface driver as the boot disk.
2. You can also put the system into single user mode and set the ROOT password, which will involve modifying CMDLINE.

@george

• Update GPU driver to Panfrost
• Update RKMPP video hardware decoding
• Update default language to English
• Install an MPV video player that supports RKMPP hardware video decoding
• Install Chromium browser to solve firefox network video freeze issue
• Install Cheese camera preview software
  
  

@airobot机器人开发
你手上有完整的SDK吗，我邮件发一份给你，里边有比较详细的文档。

@jugg
可以提供一下异常时候的log信息。

@zehui
1.目前硬件是强制SPI启动的，如下图硬件配置，如果要改为扫描启动方式，可以去掉R18的电阻。

2.目前使用的是rockchip的loader和uboot。github的uboot源码有包括SPL部分。用户可以自行修改，DDRBIN目前没有开放源码只有二进制文件。

@zehui
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.

CHANGELOG

v1.0.0-beta

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
